Tested on v6.18. The Linux kernel CVE team has assigned CVE-2026-52960 to this issue. Affected and fixed versions =========================== Fixed in 7.0.10 with commit 86921e890fe1dea9791fb70bec552516fd47716a Fixed in 7.1 with commit 544576f0f05c4a759806acddfaaeb686f14fb4b0 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-2026-52960 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: fs/ceph/addr.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/86921e890fe1dea9791fb70bec552516fd47716a https://git.kernel.org/stable/c/544576f0f05c4a759806acddfaaeb686f14fb4b0
