CVE-2023-52682

CVE-2023-52682 is a Linux kernel vulnerability affecting the f2fs file system. The issue occurs when an inode is compressed but not encrypted, where the code misses calling f2fs_wait_on_block_writeback() to wait for GCed page writeback in the IPU write path, allowing out-of-order GC and IO to cau...

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...
