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.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2

This CVE is not in the KEV list.

The EPSS score is 0.00177.
