Add an internal consistency check before any such domains descriptors accesses. The Linux kernel CVE team has assigned CVE-2022-48655 to this issue. Affected and fixed versions =========================== Fixed in 5.15.71 with commit 1f08a1b26cfc Fixed in 5.19.12 with commit 8e65edf0d376 Fixed in 6.0 with commit e9076ffbcaed 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-2022-48655 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/firmware/arm_scmi/reset.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/1f08a1b26cfc53b7715abc46857c6023bb1b87de https://git.kernel.org/stable/c/8e65edf0d37698f7a6cb174608d3ec7976baf49e https://git.kernel.org/stable/c/e9076ffbcaed5da6c182b144ef9f6e24554af268
