CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-43863 – drm/vmwgfx: Fix a deadlock in dma buf fence polling
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.
