CVE-2024-43882 – exec: Fix ToCToU between perm check and set-uid/gid usage
https://notcve.org/view.php?id=CVE-2024-43882
21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: exec: Fix ToCToU between perm check and set-uid/gid usage When opening a file for exec via do_filp_open(), permission checking is done against the file's metadata at that moment, and on success, a file pointer is passed back. Much later in the execve() code path, the file metadata (specifically mode, uid, and gid) is used to determine if/how to set the uid and gid. However, those values may have changed since the permissions check, meaning ... • https://git.kernel.org/stable/c/d5c3c7e26275a2d83b894d30f7582a42853a958f • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

CVE-2024-43867 – drm/nouveau: prime: fix refcount underflow
https://notcve.org/view.php?id=CVE-2024-43867
20 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: prime: fix refcount underflow Calling nouveau_bo_ref() on a nouveau_bo without initializing it (and hence the backing ttm_bo) leads to a refcount underflow. Instead of calling nouveau_bo_ref() in the unwind path of drm_gem_object_init(), clean things up manually. (cherry picked from commit 1b93f3e89d03cfc576636e195466a0d728ad8de5) In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: prime: fix refcou... • https://git.kernel.org/stable/c/ab9ccb96a6e6f95bcde6b8b2a524370efdbfdcd6 •

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.

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.

CVE-2024-43854 – block: initialize integrity buffer to zero before writing it to media
https://notcve.org/view.php?id=CVE-2024-43854
17 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: block: initialize integrity buffer to zero before writing it to media Metadata added by bio_integrity_prep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory. Fix this by adding the __GFP_ZERO flag to allocations for writes. In the Linux kernel, the following... • https://git.kernel.org/stable/c/7ba1ba12eeef0aa7113beb16410ef8b7c748e18b • CWE-401: Missing Release of Memory after Effective Lifetime •
