How to fix?

Upgrade SLES:15.6 glibc-devel to version 2.38-150600.14.58.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-devel package and not the glibc-devel package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Passing an effectively empty string to the ,ccs= syntax extension of the mode argument in the fopen function in the GNU C Library version 2.45 or earlier may result in a heap buffer overflow when the mode string input to the function is attacker controlled.

This usage pattern is not seen in applications in common GNU/Linux distributions and applications that process user-supplied values for ccs should not pass them through without validation.
