Hi,
The following vulnerability was published for glibc.
CVE-2025-5702[0]:
| The strcmp implementation optimized for the Power10 processor in the
| GNU C Library version 2.39 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.
