Severity: important

Hi,
The following vulnerability was published for glibc.
CVE-2025-5745[0]:
| The strncmp implementation optimized for the Power10 processor in
| the GNU C Library version 2.40 and later writes to vector registers
| v20 to v31 without saving contents from the caller (those registers
| are defined as non-volatile registers by the powerpc64le ABI),
| resulting in overwriting of its contents and potentially altering
| control flow of the caller, or leaking the input strings to the
| function to other parts of the program.
