CVE-2026-31493 1 Linux 1 Linux Kernel 2026-11-05 7.8 High
In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix use of completion ctx after free On admin queue completion handling, if the admin command completed with error we print data from the completion context. The issue is that we already freed the completion context in polling/interrupts handler which means we print data from context in an unknown state (it might be already used again). Change the admin submission flow so alloc/dealloc of the context will be symmetric and dealloc will be called after any potential use of the context.
CVE-2026-31485 1 Linux 1 Linux Kernel 2026-11-05 7.8 High
In the Linux kernel, the following vulnerability has been resolved: spi: spi-fsl-lpspi: fix teardown order issue (UAF) There is a teardown order issue in the driver. The SPI controller is registered using devm_spi_register_controller(), which delays unregistration of the SPI controller until after the fsl_lpspi_remove() function returns. As the fsl_lpspi_remove() function synchronously tears down the DMA channels, a running SPI transfer triggers the following NULL pointer dereference due to use after free: | fsl_lpspi 42550000.spi: I/O Error in DMA RX | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [...] | Call trace: | fsl_lpspi_dma_transfer+0x260/0x340 [spi_fsl_lpspi] | fsl_lpspi_transfer_one+0x198/0x448 [spi_fsl_lpspi] | spi_transfer_one_message+0x49c/0x7c8 | __spi_pump_transfer_message+0x120/0x420 | __spi_sync+0x2c4/0x520 | spi_sync+0x34/0x60 | spidev_message+0x20c/0x378 [spidev] | spidev_ioctl+0x398/0x750 [spidev] [...] Switch from devm_spi_register_controller() to spi_register_controller() in fsl_lpspi_probe() and add the corresponding spi_unregister_controller() in fsl_lpspi_remove().
CVE-2026-23454 1 Linux 1 Linux Kernel 2026-11-05 7.0 High
In the Linux kernel, the following vulnerability has been resolved: net: mana: fix use-after-free in mana_hwc_destroy_channel() by reordering teardown A potential race condition exists in mana_hwc_destroy_channel() where hwc->caller_ctx is freed before the HWC's Completion Queue (CQ) and Event Queue (EQ) are destroyed. This allows an in-flight CQ interrupt handler to dereference freed memory, leading to a use-after-free or NULL pointer dereference in mana_hwc_handle_resp(). mana_smc_teardown_hwc() signals the hardware to stop but does not synchronize against IRQ handlers already executing on other CPUs. The IRQ synchronization only happens in mana_hwc_destroy_cq() via mana_gd_destroy_eq() -> mana_gd_deregister_irq(). Since this runs after kfree(hwc->caller_ctx), a concurrent mana_hwc_rx_event_handler() can dereference freed caller_ctx (and rxq->msg_buf) in mana_hwc_handle_resp(). Fix this by reordering teardown to reverse-of-creation order: destroy the TX/RX work queues and CQ/EQ before freeing hwc->caller_ctx. This ensures all in-flight interrupt handlers complete before the memory they access is freed.
CVE-2026-42014 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-05 6.6 Medium
A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.
CVE-2026-5165 1 Redhat 2 Enterprise Linux, Virtio-win 2026-11-05 6.7 Medium
A flaw was found in virtio-win, specifically within the VirtIO Block (BLK) device. When the device undergoes a reset, it fails to properly manage memory, resulting in a use-after-free vulnerability. This issue could allow a local attacker to corrupt system memory, potentially leading to system instability or unexpected behavior.
CVE-2026-121963 1 Freerdp 1 Freerdp 2026-11-05 5.9 Medium
FreeRDP before 3.32.2 contains a use-after-free vulnerability in the asynchronous dynamic rdpsnd channel that allows malicious RDP servers to trigger freed callback access by closing the channel with queued audio PDUs. Attackers can send a training PDU then close the channel so the playback thread reads the freed callback in rdpsnd_virtual_channel_write, crashing the client.
CVE-2026-117997 1 Mozilla 1 Firefox 2026-11-05 9.6 Critical
Sandbox escape due to use-after-free in the Widget component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6.
CVE-2026-118014 1 Mozilla 1 Firefox 2026-11-05 8.8 High
Use-after-free in the JavaScript Engine: JIT component. This vulnerability was fixed in Firefox 159 and Thunderbird 159.
CVE-2026-2436 3 Gnome, Libsoup, Redhat 4 Libsoup, Libsoup, Enterprise Linux and 1 more 2026-11-05 6.5 Medium
A flaw was found in libsoup's SoupServer. A remote attacker could exploit a use-after-free vulnerability where the `soup_server_disconnect()` function frees connection objects prematurely, even if a TLS handshake is still pending. If the handshake completes after the connection object has been freed, a dangling pointer is accessed, leading to a server crash and a Denial of Service.
CVE-2026-121955 1 Freerdp 1 Freerdp 2026-11-05 7.5 High
FreeRDP before 3.32.2 contains a use-after-free vulnerability in Emulate_SCardReleaseContext that frees the emulated SCardContext before its worker thread is cancelled and joined. A malicious server can send ESTABLISHCONTEXT, a long-timeout GETSTATUSCHANGE, then RELEASECONTEXT smartcard IRPs to corrupt heap memory or crash clients using smartcard emulation.
CVE-2026-121957 1 Freerdp 1 Freerdp 2026-11-05 7.5 High
FreeRDP before 3.32.2 contains a use-after-free vulnerability that allows malicious RDP servers to corrupt client memory by racing the RDPGFX ResetGraphics handler against the planar bitmap decoder. Attackers can send ResetGraphics while concurrently sending compressed bitmaps of 32 bpp or more to trigger heap use-after-free or out-of-bounds read/write on shared planar buffers.
CVE-2026-121961 1 Freerdp 1 Freerdp 2026-11-05 5.9 Medium
FreeRDP before 3.32.2 contains a use-after-free vulnerability in the freerdp-proxy DRDYNVC tracker when intercepting the drdynvc channel. A malicious target server can repeatedly send CREATE_REQUEST_PDU for an active channel id, racing front DATA handling to free a borrowed context and crash the proxy process.
