The core of _gaccess_shadow_fault() has been split into ___gaccess_shadow_fault() in order to simplify locking. The Linux kernel CVE team has assigned CVE-2026-72293 to this issue. Affected and fixed versions =========================== Issue introduced in 7.0 with commit e38c884df92119d96f652d51f82661dd2fc0b885 and fixed in 7.1.5 with commit 0c3d4ca328e661cb4eda3bb344ea17e4b6a63171 Issue introduced in 7.0 with commit e38c884df92119d96f652d51f82661dd2fc0b885 and fixed in 7.2-rc1 with commit 668e70cc545e2659f3c4adad20a0883533042473 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-72293 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: arch/s390/kvm/gaccess.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/0c3d4ca328e661cb4eda3bb344ea17e4b6a63171 https://git.kernel.org/stable/c/668e70cc545e2659f3c4adad20a0883533042473
