The Linux kernel CVE team has assigned CVE-2025-22008 to this issue. Affected and fixed versions =========================== Fixed in 6.1.132 with commit 270fe5c090f62dfce1cad0f5053e4827a6f50df4 Fixed in 6.6.85 with commit 998b1aae22dca87da392ea35f089406cbef6032d Fixed in 6.12.21 with commit a99f1254b11eaadd0794b74a8178bad92ab01cae Fixed in 6.13.9 with commit 21e3fdf3146f9c63888d6bfabbd553434a5fb93f Fixed in 6.14 with commit 2c7a50bec4958f1d1c84d19cde518d0e96a676fd 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-2025-22008 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: drivers/regulator/core.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/270fe5c090f62dfce1cad0f5053e4827a6f50df4 https://git.kernel.org/stable/c/998b1aae22dca87da392ea35f089406cbef6032d https://git.kernel.org/stable/c/a99f1254b11eaadd0794b74a8178bad92ab01cae https://git.kernel.org/stable/c/21e3fdf3146f9c63888d6bfabbd553434a5fb93f https://git.kernel.org/stable/c/2c7a50bec4958f1d1c84d19cde518d0e96a676fd
