CVE-2024-43864 – net/mlx5e: Fix CT entry update leaks of modify header context
https://notcve.org/view.php?id=CVE-2024-43864
20 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix CT entry update leaks of modify header context The cited commit allocates a new modify header to replace the old one when updating CT entry. But if failed to allocate a new one, eg. exceed the max number firmware can support, modify header will be an error pointer that will trigger a panic when deallocating it. And the old modify header point is copied to old attr. When the old attr is freed, the old modify header is lost. Fi... • https://git.kernel.org/stable/c/94ceffb48eac7692677d8093dcde6965b70c4b35 •
CVE-2024-43863 – drm/vmwgfx: Fix a deadlock in dma buf fence polling

20 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix a deadlock in dma buf fence polling Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks. vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both... • https://git.kernel.org/stable/c/2298e804e96eb3635c39519c8287befd92460303 •
CVE-2024-43862 – net: wan: fsl_qmc_hdlc: Convert carrier_lock spinlock to a mutex

CVE-2024-43860 – remoteproc: imx_rproc: Skip over memory region when node value is NULL
https://notcve.org/view.php?id=CVE-2024-43860
17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Skip over memory region when node value is NULL In imx_rproc_addr_init() "nph = of_count_phandle_with_args()" just counts number of phandles. But phandles may be empty. So of_parse_phandle() in the parsing loop (0 < a < nph) may return NULL which is later dereferenced. Adjust this issue by adding NULL-return check.

17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: dma: fix call order in dmam_free_coherent dmam_free_coherent() frees a DMA allocation, which makes the freed vaddr available for reuse, then calls devres_destroy() to remove and free the data structure used to track the DMA allocation. Between the two calls, it is possible for a concurrent task to make an allocation with the same vaddr and add it to the devres list. If this happens, there will be two entries in the devres list with the same... • https://git.kernel.org/stable/c/9ac7849e35f705830f7b016ff272b0ff1f7ff759 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: md: fix deadlock between mddev_suspend and flush bio Deadlock occurs when mddev is being suspended while some flush bio is in progress. It is a complex issue. T1. the first flush is at the ending stage, it clears 'mddev->flush_bio' and tries to submit data, but is blocked because mddev is suspended by T4. T2. the second flush sets 'mddev->flush_bio', and attempts to queue md_submit_flush_data(), which is already running (T1) and won't execu... • https://git.kernel.org/stable/c/f9f2d957a8ea93c73182aebf7de30935a58c027d •
