CVE-2024-35784

The CVE-2024-35784 entry concerns the Linux kernel: btrfs deadlock during fiemap/extent locking. Root cause: the extent lock was held for the entire fiemap traversal, risking pagefaults and deadlocks when fiemap data is copied to user space (mkwrite during mmap). Impact: potential deadlock in fil...
