| CVE-2026-15579 | 1 Moxa | 1 Tn-4500b Series | 2026-09-18 | N/A |
| An out-of-bounds write vulnerability exists in some of the Ethernet switches because of improper validation of the username field length during Web login processing. This may allow a remote attacker to submit a specially crafted overly long input, triggering a buffer overflow that can cause the authentication process to crash and result in a Denial of Service (DoS) attack. | ||||
| CVE-2026-89873 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate HEVC EXT SPS RPS counts The HEVC SPS control carries the short-term and long-term RPS counts that decoder drivers use to walk the matching EXT SPS dynamic arrays. Reject SPS values that exceed the HEVC limits of 64 short-term sets and 32 long-term references so drivers cannot later index beyond those controls. Also reject EXT SPS ST RPS entries whose negative or positive picture counts exceed the 16-entry arrays, or whose combined delta-POC count exceeds the HEVC DPB maximum. | ||||
| CVE-2026-89881 | 1 Linux | 1 Linux Kernel | 2026-09-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: rtl2832_sdr: use vb2_video_unregister_device() on remove to fix DMA leak rtl2832_sdr_remove() runs on USB disconnect and clears dev->udev to NULL before any pending streaming teardown has run. When user space later closes its file descriptor, vb2 calls rtl2832_sdr_stop_streaming() which in turn calls rtl2832_sdr_free_stream_bufs(). That helper releases each coherent buffer with: usb_free_coherent(dev->udev, dev->buf_size, dev->buf_list[dev->buf_num], dev->dma_addr[dev->buf_num]); usb_free_coherent() returns immediately when its dev argument is NULL, so every DMA stream buffer that was live at disconnect is silently leaked. The URBs allocated in rtl2832_sdr_alloc_urbs() outlive the device for the same reason. The rtl2832_sdr driver uses vb2_fop_release() in its file_operations, so replace video_unregister_device(&dev->vdev) with vb2_video_unregister_device(&dev->vdev) and move it before clearing dev->udev. vb2_video_unregister_device() releases the vb2 queue, which synchronously runs rtl2832_sdr_stop_streaming() if streaming is active, so URBs and coherent DMA stream buffers are freed while dev->udev is still valid. vb2_video_unregister_device() locks vdev->queue->lock (vb_queue_lock) internally, and stop_streaming() locks v4l2_lock, so the previous outer mutex_lock(&dev->vb_queue_lock) / mutex_lock(&dev->v4l2_lock) pair around the unregister sequence would self-deadlock and has been removed. A short v4l2_lock critical section around dev->udev = NULL remains so any ioctl path that still holds the file descriptor sees coherent state.

| CVE-2026-19387 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more | 2026-09-18 | 7.6 High |
| A heap out-of-bounds write vulnerability was found in the GStreamer gst-plugins-bad adpcmdec element when decoding IMA/DVI ADPCM audio. Insufficient validation of the per-block sample count for multi-channel streams allows a crafted WAV file to cause writes beyond the allocated output buffer. This can lead to application crash, denial of service, memory corruption, or potentially arbitrary code execution when untrusted media is processed. | ||||
| CVE-2026-89905 | 1 Linux | 1 Linux Kernel | 2026-09-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Move arena register slot below TCC context Currently, the stack layout places the optional arena register slot above the tail call counter context. When arena_vm_start is dynamically enabled, it shifts the relative offset of the tcc_ptr slot within the stack frame, causing hardcoded tracking macros to mismatch and leading to memory misalignment or corruption potentially. To fix this, move the arena register save and restore sequences below the tail call counter context slots in both build_prologue() and the epilogue. Update __build_epilogue() to insert a proper offset decrement to safely skip the unneeded tcc_ptr reading block while accurately aligning with the relocated arena slot at the very bottom. With this patch, the tcc_ptr slot is always positioned at a fixed distance directly underneath the base callee-saved registers that is independent of whether the arena features are on. | ||||
| CVE-2026-89907 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Validate MSI data before routing it to EIOINTC pch_msi_set_irq() passes e->msi.data straight into eiointc_set_irq() as the irq number. The MSI data comes from userspace, that either via a KVM_IRQ_ROUTING_MSI entry set with KVM_SET_GSI_ROUTING (used by irqfd and KVM_IRQ_LINE) or directly via KVM_SIGNAL_MSI, and is never checked against EIOINTC_IRQS. eiointc_set_irq() uses the value with __set_bit()/__clear_bit() on the 256-bit isr bitmap, eiointc_update_irq() then indexes sw_coremap[] and the per-cpu coreisr/sw_coreisr bitmaps with it. Therefore a data value >= 256 reads and writes memory past the end of those arrays, i.e. any process holding a VM fd can corrupt kernel memory beyond the allocation of loongarch_eiointc. Reject MSI data that doesn't fit in the EIOINTC irq space. The DMSINTC path is unaffected as it decodes the vector from the address and masks it. | ||||
| CVE-2026-89920 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix memory corruption by not reinjecting CK machine checks Channel-subsystem damage machine checks are for the host channel subsystem. The guest channel subsystem is emulated in the userspace VMM. There is no point in forwarding such machine checks into the guest. This also simplifies the machine check reinjection and avoids kfree of a stack variable as reported by sashiko. There might be still machine checks that have the ck bit set with another bit (like instruction damage), mask out the CK bit in s390_backup_mcck_info(), like the CP and ED bits already are. | ||||
| CVE-2026-90011 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Reserve a terminator byte for the login payload iscsi_target_check_login_request() rejects a login PDU whose DataSegmentLength exceeds MAX_KEY_VALUE_PAIRS, but the test is '>' and login->req_buf is allocated with exactly MAX_KEY_VALUE_PAIRS bytes. Since iscsit_get_login_rx() receives payload_length + padding bytes, where padding = ((-payload_length) & 3); any payload_length from 8189 to 8192 fills the whole 8192 byte buffer. The write stays in bounds, but no byte is left for a NUL terminator. The buffer is subsequently consumed as a C string. In the CHAP path chap_check_algorithm() calls kstrdup(a_str), and extract_param() calls strstr(in_buf, pattern) followed by strlen_semi(), none of which take a length. convert_null_to_semi() additionally rewrites every embedded NUL to ';', so even a payload made of well formed NUL separated key=value records is left without a terminator. These walk past the end of the object into adjacent slab memory. It is reachable by an unauthenticated initiator against a portal configured for CHAP; when authentication is not required iscsi_login_zero_tsih_s2() rewrites AuthMethod to None and the CHAP path is never entered. Allocate one extra byte. kzalloc() zeroes it and nothing ever writes to it, as every writer copies to offset 0 for at most MAX_KEY_VALUE_PAIRS bytes, so the buffer is always terminated. | ||||
| CVE-2026-90000 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: HID: rmi: fix OOB access with undersized RMI reports The hid-rmi driver sizes its writeReport/readReport buffer purely from the report descriptor supplied by the device, with no minimum bound: data->input_report_size = hid_report_len(input_report); data->output_report_size = hid_report_len(output_report); alloc_size = data->output_report_size + data->input_report_size; data->writeReport = devm_kzalloc(&hdev->dev, alloc_size, GFP_KERNEL); data->readReport = data->writeReport + data->output_report_size; but then reads and writes fixed offsets into it. A device declaring a 1-byte output and a 1-byte input report makes hid_report_len() return 2 for each, so alloc_size is 4, while rmi_set_page() -- reached unconditionally at probe time through rmi_input_configured() -- stores writeReport[4] and rmi_hid_read_block() stores writeReport[0..5]. Since readReport lives at writeReport + output_report_size, those stores also corrupt the window the next reply is parsed out of. The read path is worse: the copy length comes from readReport[1], which the device fills in and can be up to 255, and the copy starts at &readReport[2] with no regard for input_report_size, so it runs past the end of the allocation into adjacent slab objects. This does not even need a lying device -- rmi_f01_probe() issues a fixed 21-byte register read, so any device declaring an input report smaller than 23 bytes reads out of bounds even when it answers truthfully. Those bytes become the register values the RMI core acts on: rmi_f01_probe() prints them to the kernel log as the product id and exports them through the mode 0444 sysfs attribute of the same name, and rmi_driver_set_irq_bits() sends them back to the device as the interrupt mask, so an undersized report descriptor leaks heap contents both to unprivileged userspace and to the device itself. The write path has no bound either: rmi_hid_write_block() copies an unbounded len to &writeReport[4], and the largest caller a device can drive at probe time is rmi_driver_set_irq_bits(), whose length is derived from the interrupt source counts the device declares in its Page Description Table. Finally, the read loop cannot terminate on a zero-length reply: such a reply copies nothing and advances neither bytes_read nor bytes_needed, and because a reply did arrive the one second wait_event_timeout() does not fire either, so a device answering 0 forever keeps the loop running inside the probe worker with page_mutex held. khungtaskd does not notice, because every reply wakes the task. Reject reports too small for what the driver builds -- 6 output bytes for the write reports and 3 input bytes for the read handshake -- at probe time, clamp the write and the read copy to the report sizes the device declared, and treat a zero-length reply as an error. A device refused this way is started as an ordinary HID device, like one that does not carry the RMI report ids at all. RMI_DEVICE must not be left set in device_flags on that path, because rmi_input_configured() would then run the RMI setup and reach rmi_set_page(), which writes the writeReport buffer the refusal just skipped allocating. The bit can arrive set: rmi_probe() copies id->driver_data into device_flags before the report checks, and a bind through the new_id sysfs attribute can supply driver_data with RMI_DEVICE (BIT(0)) set. Strip the bit where driver_data is copied, so RMI_DEVICE keeps meaning exactly "this probe validated the reports"; the three jumps to start that predate this patch are covered as well. The error path also clears RMI_READ_DATA_PENDING on its way out, because that flag is what the wait at the top of the loop tests: leaving it set would make every later wait_event_timeout() return immediately on the stale reply and kill the read path for the rest of the device's life. Clamping does not regress working hardware: the read loop already handles ---truncated--- | ||||
| CVE-2026-90017 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix OOB read in rtw_action_frame_parse() rtw_action_frame_parse() takes a frame_len parameter but never actually checks it before indexing into the frame body: const u8 *frame_body = frame + sizeof(struct ieee80211_hdr_3addr); ... c = frame_body[0]; ... a = frame_body[1]; frame_body already points 24 bytes (sizeof(struct ieee80211_hdr_3addr)) into frame, so reading frame_body[0] and frame_body[1] requires frame_len >= 26. A management action frame shorter than that (e.g. exactly 24 bytes, the minimum a malicious peer can send) causes a 1-2 byte out-of-bounds read. This is reachable from rtw_cfg80211_monitor_if_xmit_entry() and cfg80211_rtw_mgmt_tx() in ioctl_cfg80211.c, both of which pass attacker/user-influenced frame buffers and lengths straight through. Add the missing length check before frame_body is dereferenced. | ||||

| CVE-2026-85756 | 1 Sshnet | 1 Ssh.net | 2026-09-18 | 7.5 High |
| SSH.NET is a Secure Shell (SSH) library for .NET. Prior to 2026.0.0, ScpClient places caller-supplied remote paths into the command used to run scp on the server, and the default RemotePathTransformation.DoubleQuote transformation cannot safely quote every remote command interpreter. When an application passes an attacker-controlled path to a shell-based server, shell metacharacters not neutralized by the active IRemotePathTransformation can execute commands as the authenticated SSH user. Exploitation requires a shell-based server and a path crafted for that shell's parsing rules; non-shell servers and paths fully neutralized by the selected transformation are not affected. RemotePathTransformation.ShellQuote is available for POSIX shells, while SftpClient avoids a remote shell entirely. This issue is fixed in version 2026.0.0. | ||||

| CVE-2026-73639 | 2026-09-18 | N/A | ||
| Imager::File::PNG versions from 1.003 before 1.004 for Perl write past the end of the row buffer reading a PNG with a tRNS transparency chunk in read_direct8. With a tRNS chunk, read_direct8() adds an alpha channel to the image it creates but still sizes the row buffer from the original channel count. libpng expands the transparency into that extra channel, so png_read_row() fills one channel more than the buffer holds, at one byte per sample, and writes width bytes past the end of the allocation. Palette images go to read_paletted() and 16-bit images to read_direct16(), which sizes its buffer from png_get_rowbytes() and allocates enough for the expanded row. The same reader ships bundled in the Imager distribution. Reading an attacker-supplied PNG through Imager->read() corrupts the heap, which can crash the process. | ||||
