UBUNTU-CVE-2023-52935

In the Linux kernel, the following vulnerability has been resolved: mm/khugepaged: fix -anonvma race If an -anonvma is attached to the VMA, collapseandfreepmd requires it to be locked. Page table traversal is allowed under any one of the mmap lock, the anonvma lock if the VMA is associated with a...

CVE-2023-52935

CVE-2023-52935 refers to a Linux kernel vulnerability in mm/khugepaged related to an ->anon_vma race when removing page tables. The issue could allow concurrent access to page tables during rmap traversal if an anon_vma is shared; the fix adds a re-check after acquiring the mmap lock so there ...

CVE-2022-49272

CVE-2022-49272 affects the Linux kernel in ALSA: pcm code. The root cause is a potential AB/BA deadlock between PCM runtime→buffer_mutex and mm→mmap_lock triggered by concurrent access via ALSA and OSS during read/write and mmap/path IOCTLs. The fix replaces the buffer_mutex protection in read/wr...

CVE-2024-46838

In the Linux kernel, the following vulnerability has been resolved: userfaultfd: don't BUGON if khugepaged yanks our page table Since khugepaged was changed to allow retracting page tables in file mappings without holding the mmap lock, these BUGONs are wrong - get rid of them. We could also remo...

UBUNTU-CVE-2023-52737

In the Linux kernel, the following vulnerability has been resolved: btrfs: lock the inode in shared mode before starting fiemap Currently fiemap does not take the inode's lock VFS lock, it only locks a file range in the inode's io tree. This however can lead to a deadlock if we have a concurrent...
