06 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/vas: Add close() callback in vas_vm_ops struct The mapping VMA address is saved in VAS window struct when the paste address is mapped. This VMA address is used during migration to unmap the paste address if the window is active. The paste address mapping will be removed when the window is closed or with the munmap(). But the VMA address in the VAS window is not updated with munmap() which is causing invalid access during mig... • https://git.kernel.org/stable/c/37e6764895ef7431f45ff603a548549d409993d2 •
CVE-2024-56764 – ublk: detach gendisk from ublk device if add_disk() fails
https://notcve.org/view.php?id=CVE-2024-56764
06 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: ublk: detach gendisk from ublk device if add_disk() fails Inside ublk_abort_requests(), gendisk is grabbed for aborting all inflight requests. And ublk_abort_requests() is called when exiting the uring context or handling timeout. If add_disk() fails, the gendisk may have been freed when calling ublk_abort_requests(), so use-after-free can be caused when getting disk's reference in ublk_abort_requests(). Fixes the bug by detaching gendisk f... • https://git.kernel.org/stable/c/bd23f6c2c2d00518e2f27f2d25cef795de9bee56 •

06 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: x86/fred: Clear WFE in missing-ENDBRANCH #CPs An indirect branch instruction sets the CPU indirect branch tracker (IBT) into WAIT_FOR_ENDBRANCH (WFE) state and WFE stays asserted across the instruction boundary. When the decoder finds an inappropriate instruction while WFE is set ENDBR, the CPU raises a #CP fault. For the "kernel IBT no ENDBR" selftest where #CPs are deliberately triggered, the WFE state of the interrupted context needs to ... • https://git.kernel.org/stable/c/a5f6c2ace9974adf92ce65dacca8126d90adabfe •

CVE-2024-56758 – btrfs: check folio mapping after unlock in relocate_one_folio()

06 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: btrfs: check folio mapping after unlock in relocate_one_folio() When we call btrfs_read_folio() to bring a folio uptodate, we unlock the folio. The result of that is that a different thread can modify the mapping (like remove it with invalidate) before we call folio_lock(). This results in an invalid page and we need to try again. In particular, if we are relocating concurrently with aborting a transaction, this can result in a crash like t... • https://git.kernel.org/stable/c/e7f1326cc24e22b38afc3acd328480a1183f9e79 •

CVE-2024-56756 – nvme-pci: fix freeing of the HMB descriptor table

29 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix freeing of the HMB descriptor table The HMB descriptor table is sized to the maximum number of descriptors that could be used for a given device, but __nvme_alloc_host_mem could break out of the loop earlier on memory allocation failure and end up using less descriptors than planned for, which leads to an incorrect size passed to dma_free_coherent.
