| CVE-2026-97512 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: spi: spi-qcom-qspi: Fix incomplete error handling in runtime PM The runtime PM functions had incomplete error handling that could leave the system in an inconsistent state. If any operation failed midway through suspend or resume, some resources would be left in the wrong state while others were already changed, leading to potential clock/power imbalances. Reorder the suspend/resume sequences to avoid brownout risk by ensuring the performance state is set appropriately before clocks are enabled and clocks are disabled before dropping the performance state. Fix by adding proper error checking for all operations and using goto-based cleanup to ensure all successfully acquired resources are properly released on any error. | ||||
| CVE-2026-97510 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Release request if tb_cfg_request() fails in __tb_xdomain_response() If tb_cfg_request() fails setting up the request (for example the control channel is shut down already) it returns an error without calling the callback. To avoid leaking that memory, call tb_cfg_request_put() if tb_cfg_request() fails. | ||||
| CVE-2026-97509 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Keep XDomain reference during the lifetime of a service This is needed because we release the service ID in tb_service_release() and the ID array is owned by the parent XDomain. | ||||
| CVE-2026-97508 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Set tb->root_switch to NULL when domain is stopped Similarly what we do with the firmware connection manager. This makes tb_xdp_handle_request() return error to the remote host. However, we need to make sure we keep the uuid alive so that we can reply until the whole domain is released. | ||||
| CVE-2026-97507 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: media: dm1105: fix missing error check for dma_alloc_coherent The return value of dm1105_dma_map(), which handles DMA memory allocation, is ignored in dm1105_hw_init(). If dma_alloc_coherent() fails, the driver will proceed using a NULL pointer for DMA transfers, leading to a kernel oops or invalid hardware access. Fix this by checking the return value and propagating -ENOMEM on failure. | ||||
| CVE-2026-97506 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: crypto: ixp4xx - fix buffer chain unwind on allocation failure chainup_buffers() builds a linked list of buffer descriptors for a scatterlist. If dma_pool_alloc() fails while constructing the list, the current code sets buf to NULL and later dereferences it unconditionally at the end of the function: buf->next = NULL; buf->phys_next = 0; This can lead to a null-pointer dereference on allocation failure. If the failure happens after part of the descriptor chain has already been allocated and DMA-mapped, the partially constructed chain also needs to be released. Fix this by terminating the partially constructed chain on allocation failure and letting the callers unwind it via their existing cleanup paths. Also fix ablk_perform() to preserve the hook pointers before checking for failure, so partially built chains can be freed correctly. | ||||
| CVE-2026-97502 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mmc: davinci: avoid NULL deref of host->data in IRQ handler mmc_davinci_irq() returns early only when both host->cmd and host->data are NULL: if (host->cmd == NULL && host->data == NULL) { ... return IRQ_NONE; } So we may legitimately reach the rest of the handler with host->data == NULL (and therefore data == NULL). The DATDNE branch already guards against this with an explicit "if (data != NULL)" check, but the subsequent TOUTRD ("read data timeout") and CRCWR/CRCRD ("data CRC error") branches dereference data unconditionally: if (qstatus & MMCST0_TOUTRD) { data->error = -ETIMEDOUT; <-- NULL deref ... davinci_abort_data(host, data); } if (qstatus & (MMCST0_CRCWR | MMCST0_CRCRD)) { data->error = -EILSEQ; <-- NULL deref ... } If either bit is set in qstatus while host->data is NULL, the kernel will crash inside the IRQ handler. smatch flags this: drivers/mmc/host/davinci_mmc.c:933 mmc_davinci_irq() error: we previously assumed 'data' could be null (see line 914) Gate both branches on a non-NULL data, matching the existing pattern used by the DATDNE branch. No functional change for callers where data is non-NULL, which is the only case in which these branches did meaningful work before this change. | ||||
| CVE-2026-97500 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: phy: check length before parsing PHY status IE Hardware might report PHY status IE with unexpected length, and parser might access out of range. Check the length ahead. | ||||
| CVE-2026-97499 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: coresight: perf: Retrieve path and source from event data ETM perf callbacks currently use the per-CPU csdev_src pointer, which can race with updates during device registration and unregistration. The AUX setup already builds and stores the path in the event data. Use this path to retrieve the source instead of csdev_src to avoid the race. Export coresight_get_source() and add etm_event_get_ctxt_path() to retrieve the context's path and its source with READ_ONCE() / WRITE_ONCE() accessors. Give the comments to explain why this approach is safe when pause or resume callbacks preempt the disable callback (e.g. via NMI). | ||||
| CVE-2026-97498 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction mqd and fw objects are queue core objects which should remain valid and never be unmapped and evicted for user queues to work properly. During eviction if these buffers are evicted the hw continue to use the invalid addresses and caused page faults and system hung. | ||||
| CVE-2026-97494 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate and share PSP fw_pri_buf copies via psp_copy_fw Change psp_copy_fw from void to int: return -ENODEV when drm_dev_enter fails, and -EINVAL when the image size is zero or larger than the 1 MiB PSP private buffer. Replace open-coded memset/memcpy into fw_pri_buf with psp_copy_fw. | ||||
| CVE-2026-97489 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bfs: handle set_blocksize failures bfs uses buffer_heads, which don't handle block size > PAGE_SIZE well. Without this, mounting will hit the BUG_ON(offset >= folio_size(folio)); in folio_set_bh on the first __bread_gfp call. | ||||
| CVE-2026-97487 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: jfs: handle set_blocksize failures jfs uses buffer_heads, which don't handle block size > PAGE_SIZE well. Without this, mounting we will hit the BUG_ON(offset >= folio_size(folio)); in folio_set_bh on the first __bread_gfp call. | ||||
| CVE-2026-97485 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: omfs: handle set_blocksize failures omfs uses buffer_heads, which don't handle block size > PAGE_SIZE well. Without this, mounting we will hit the BUG_ON(offset >= folio_size(folio)); in folio_set_bh on the first __bread_gfp call. | ||||
| CVE-2026-97484 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usbip: vhci_hcd: fix NULL deref in status_show_vhci platform_get_drvdata() can return NULL if a VHCI host controller's probe failed (e.g. due to USB bus number exhaustion). status_show_vhci() checked for a NULL pdev but not for a NULL hcd returned by platform_get_drvdata(). Passing NULL to hcd_to_vhci_hcd() does not return NULL - it returns a pointer offset of 0x260, causing a NULL pointer dereference when that value is subsequently dereferenced. Add a NULL check on hcd before calling hcd_to_vhci_hcd(). Move status_show_not_ready() above status_show_vhci() to make it callable from the new error path without a forward declaration. | ||||
| CVE-2026-97482 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usb: gadget: goku_udc: avoid NULL deref of dev->driver in INT_USBRESET log goku_irq() handles a number of bus events under a single ep0 path. It already guards the gadget driver suspend/resume callbacks against a NULL ->driver: if (dev->gadget.speed != USB_SPEED_UNKNOWN && dev->driver && dev->driver->resume) { spin_unlock(&dev->lock); dev->driver->resume(&dev->gadget); ... } but the very next branch unconditionally dereferences dev->driver when an INT_USBRESET arrives: if (stat & INT_USBRESET) { ACK(INT_USBRESET); INFO(dev, "USB reset done, gadget %s\n", dev->driver->driver.name); } If the controller raises INT_USBRESET before any gadget driver has been bound (or after one has been unbound), dev->driver is NULL and the printk dereferences NULL. smatch flags the inconsistency: drivers/usb/gadget/udc/goku_udc.c:1618 goku_irq() error: we previously assumed 'dev->driver' could be null (see line 1607) Fall back to a placeholder when the gadget driver is not bound. No functional change while a gadget driver is bound. | ||||
| CVE-2026-97480 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: tty: serial: 8250: protect against NULL uart->port.dev in register serial8250_register_8250_port() conditionally copies uart->port.dev from up->port.dev only when up->port.dev is non-NULL: if (up->port.dev) { uart->port.dev = up->port.dev; ... } So if both the existing uart slot and up have a NULL ->dev, uart->port.dev remains NULL. The very next ACPI companion check then dereferences it unconditionally: if (!has_acpi_companion(uart->port.dev)) { has_acpi_companion() reads dev->fwnode without a NULL guard (include/linux/acpi.h), so this NULL-derefs the kernel for the remaining no-dev case rather than just skipping the mctrl_gpio_init() initialisation as intended. smatch flags the inconsistency: drivers/tty/serial/8250/8250_core.c:767 serial8250_register_8250_port() error: 'uart->port.dev' could be null (see line 719) Guard the call with a NULL check so register continues to work for callers that legitimately have no parent device (legacy non-OF/non-ACPI registrations). No functional change for callers that pass a non-NULL ->dev. | ||||
| CVE-2026-97478 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: virt: acrn: Fix irqfd use-after-free during eventfd shutdown acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup can race and free the same struct hsm_irqfd: CPU0 CPU1 ---- ---- eventfd_release() wake_up_poll(EPOLLHUP) hsm_irqfd_wakeup() queue_work(&irqfd->shutdown) acrn_irqfd_deassign() hsm_irqfd_shutdown() list_del_init() eventfd_ctx_remove_wait_queue() eventfd_ctx_put() kfree(irqfd) hsm_irqfd_shutdown_work() container_of(work, ..., shutdown) irqfd->vm <-- use-after-free The deassign path freed the irqfd while a shutdown work item was already queued by EPOLLHUP (or vice versa), so the work item could resurrect a dangling pointer through container_of(). Switch to the lifetime model used by KVM irqfds: - Deassign/deinit only deactivate the irqfd: remove it from vm->irqfds under irqfds_lock and queue the cleanup work. - hsm_irqfd_shutdown_work() becomes the sole owner that unhooks the eventfd waitqueue entry, drops the eventfd reference and frees the irqfd. - A new HSM_IRQFD_FLAG_SHUTDOWN bit guarded by test_and_set_bit() ensures the cleanup work is queued at most once, no matter how many of {EPOLLHUP, deassign, deinit} fire concurrently. This is safe to call from the waitqueue callback, which runs with wqh->lock held and IRQs disabled and therefore cannot take irqfds_lock. - acrn_irqfd_deassign() flushes vm->irqfd_wq before returning so the eventfd is fully detached on return. acrn_irqfd_deinit() deactivates every irqfd, flushes the workqueue and only then destroys it, so no path can queue_work() onto a torn-down workqueue. - acrn_irqfd_assign() now installs the eventfd waitqueue entry and publishes the irqfd to vm->irqfds under irqfds_lock, so the irqfd is never visible to deassign/deinit before its waitqueue entry is in place, and any EPOLLHUP that fires in the assign window queues cleanup work that blocks on irqfds_lock until publication is done. | ||||
| CVE-2026-97475 | 1 Linux | 1 Linux Kernel | 2026-09-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/tegra/soctherma: Switch to devm cooling device registration Use devm_thermal_of_cooling_device_register() to simplify resource management and avoid manual cleanup in error paths. As a side effect this change has the benefit of solving an existing issue. Before, the function tegra_soctherm_remove() only called debugfs_remove_recursive() and never called thermal_cooling_device_unregister() for any of the cooling devices registered here. After the driver removal, the thermal framework's cdev list would still hold references to thermal_cooling_device objects whose devdata pointer (ts) pointed to memory already freed by the platform device's devm cleanup. With this change, the cooling device is unregistered when the driver is removed, thus fixing the issue above. | ||||
