An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2026-31482)

Note that Nessus relies on the presence of the package as reported by the vendor.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux
