27 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: mm/khugepaged: fix ->anon_vma race If an ->anon_vma is attached to the VMA, collapse_and_free_pmd() requires it to be locked. Page table traversal is allowed under any one of the mmap lock, the anon_vma lock (if the VMA is associated with an anon_vma), and the mapping lock (if the VMA is associated with a mapping); and so to be able to remove page tables, we must hold all three of them. retract_page_tables() bails out if an ->anon_vma is at... • https://git.kernel.org/stable/c/f3f0e1d2150b2b99da2cbdfaad000089efe9bf30 • CWE-416: Use After Free •

27 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: Squashfs: fix handling and sanity checking of xattr_ids count A Sysbot [1] corrupted filesystem exposes two flaws in the handling and sanity checking of the xattr_ids count in the filesystem. Both of these flaws cause computation overflow due to incorrect typing. In the corrupted filesystem the xattr_ids value is 4294967071, which stored in a signed variable becomes the negative number -225.
