Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: UDF symlink pathComponent header OOB read udf_symlink_filler() can enter udf_pc_to_char() with a partial pathComponent header. Validate that enough input remains for a complete pathComponent header before accessing it. Reject malformed symlink data that would otherwise make udf_pc_to_char() perform an out-of-bounds read.
