https://notcve.org/view.php?id=CVE-2024-43863
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 deletes the fence and removes it from the list of pending fences, for which it holds a lock. dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called. Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock. • https://git.kernel.org/stable/c/2298e804e96eb3635c39519c8287befd92460303 https://git.kernel.org/stable/c/9e20d028d8d1deb1e7fed18f22ffc01669cf3237 https://git.kernel.org/stable/c/3b933b16c996af8adb6bc1b5748a63dfb41a82bc https://git.kernel.org/stable/c/a8943969f9ead2fd3044fc826140a21622ef830e https://git.kernel.org/stable/c/c98ab18b9f315ff977c2c65d7c71298ef98be8e3 https://git.kernel.org/stable/c/e58337100721f3cc0c7424a18730e4f39844934f •

https://notcve.org/view.php?id=CVE-2024-43860
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. Found by Linux Verification Center (linuxtesting.org) with SVACE.

CVSS: 4.4EPSS: 0%CPEs: 8EXPL: 0CVE-2024-43856 – dma: fix call order in dmam_free_coherent
https://notcve.org/view.php?id=CVE-2024-43856
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 vaddr and devres_destroy() can free the wrong entry, triggering the WARN_ON() in dmam_match. Fix by destroying the devres entry before freeing the DMA allocation. kokonut //net/encryption http://sponge2/b9145fe6-0f72-4325-ac2f-a84d81075b03 • https://git.kernel.org/stable/c/9ac7849e35f705830f7b016ff272b0ff1f7ff759 https://git.kernel.org/stable/c/fe2d246080f035e0af5793cb79067ba125e4fb63 https://git.kernel.org/stable/c/2f7bbdc744f2e7051d1cb47c8e082162df1923c9 https://git.kernel.org/stable/c/257193083e8f43907e99ea633820fc2b3bcd24c7 https://git.kernel.org/stable/c/87b34c8c94e29fa01d744e5147697f592998d954 https://git.kernel.org/stable/c/f993a4baf6b622232e4c190d34c220179e5d61eb https://git.kernel.org/stable/c/1fe97f68fce1ba24bf823bfb0eb0956003473130 https://git.kernel.org/stable/c/22094f5f52e7bc16c5bf9613365049383 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
