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.</p> <p>Add the missing xgr %r12,%r12 to make the register scrub consistent across all entry points.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>s390/entry: Scrub r12 register on kernel entry</p> <p>Before commit f33f2d4c7c80 (&#34;s390/bp: remove TIF_ISOLATE_BP&#34;), all entry handlers loaded r12 with the current task pointer (lg %r12,__LC_CURRENT) for use by the BPENTER/BPEXIT macros.
