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...
