CVE-2025-37741

CVE-2025-37741 affects the Linux kernel JFS, where a race/locking path can lead to a deadlock in diFree when nlink is incorrectly derived as 0. Root cause: during inode handling for iag creation, a corrupted metapage can cause dinode’s nlink to be copied as 0, triggering diFree and a deadlock seq...

CVE-2024-56548

CVE-2024-56548 affects the Linux kernel’s hfsplus handling. The root cause is changing device logical block sizes (e.g., via LOOP_SET_BLOCK_SIZE) that can cause a write of out-of-bounds data when hfsplus_read_wrapper calls hfsplus_submit_bio. The fix introduces a new min_io_size, set to the max o...
