In the Linux kernel, the following vulnerability has been resolved:ext4: do not BUG when INLINE_DATA_FL lacks system.data xattrA syzbot fuzzed image triggered a BUG_ON in ext4_update_inline_data()when an inode had the INLINE_DATA_FL flag set but was missing thesystem.data extended attribute.Since this can happen due to a maiciouly fuzzed file system, weshouldn't BUG, but rather, report it as a corrupted file system.Add similar replacements of BUG_ON with EXT4_ERROR_INODE() iiext4_create_inline_data() and ext4_inline_data_truncate().
No PoCs from references.
