CVE-2023-52898 – xhci: Fix null pointer dereference when host dies
https://notcve.org/view.php?id=CVE-2023-52898
21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: xhci: Fix null pointer dereference when host dies Make sure xhci_free_dev() and xhci_kill_endpoint_urbs() do not race and cause null pointer dereference when host suddenly dies. Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id] virt device at the same time that xhci_kill_endpoint_urbs() tries to loop through all the device's endpoints, checking if there are any cancelled urbs left to give back. hold the xhci spinlock whi... • https://git.kernel.org/stable/c/6fac4b5cecb3928a0a81069aaa815a2edc8dd5a1 •

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Cleanup partial engine discovery failures If we abort driver initialisation in the middle of gt/engine discovery, some engines will be fully setup and some not. Those incompletely setup engines only have 'engine->release == NULL' and so will leak any of the common objects allocated. v2: - Drop the destroy_pinned_context() helper for now.

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: regulator: da9211: Use irq handler when ready If the system does not come from reset (like when it is kexec()), the regulator might have an IRQ waiting for us. If we enable the IRQ handler before its structures are ready, we crash.

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 •

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') •
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 •
