CVE-2026-31597
The CVE-2026-31597 vulnerability affects the Linux kernel OCFS2 code. A use-after-free occurs in ocfs2_fault() when VM_FAULT_RETRY triggers after filemap_fault() drops mmap_lock, allowing a concurrent munmap() to free the vm_area_struct and causing ocfs2_fault() to dereference a dangling vma. The...
