CVE-2026-31482 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:6.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
s390/entry: Scrub r12 register on kernel entry
Before commit f33f2d4c7c80 ("s390/bp: remove TIF_ISOLATE_BP"), all entry handlers loaded r12 with the current task pointer (lg %r12,__LC_CURRENT) for use by the BPENTER/BPEXIT macros. That commit removed TIF_ISOLATE_BP, dropping both the branch prediction macros and the r12 load, but did not add r12 to the register clearing sequence.
Add the missing xgr %r12,%r12 to make the register scrub consistent across all entry points.
