9c356fc32a4480a2c0e537a05f2a8617633ddad0 is the first bad commit commit 9c356fc32a4480a2c0e537a05f2a8617633ddad0 Author: Artem Sadovnikov Date: Sat Oct 5 10:06:57 2024 +0000 jfs: xattr: check invalid xattr size more strictly commit d9f9d96136cba8fedd647d2c024342ce090133c2 upstream. Commit 7c55b78818cf ("jfs: xattr: fix buffer overflow for invalid xattr") also addresses this issue but it only fixes it for positive values, while ea_size is an integer type and can take negative values, e.g. in case of a corrupted filesystem. This still breaks validation and would overflow because of implicit conversion from int to size_t in print_hex_dump(). Fix this issue by clamping the ea_size value instead.
