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-2023-53002

CVE-2023-53002 concerns the Linux kernel DRM/I915 memory leak when mmap_offset is reused. The root cause is that drm_vma_node_allow() and drm_vma_node_revoke() were not called in balanced pairs: allow is invoked once per-file per mmap_offset, while revoke was only called per-file per mmap_offset,...

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 ...
