This may lead to OOB access for index[] and other parameters. Add a sanity check for the card index and warn/correct it if it's a value out of the range. The Linux kernel CVE team has assigned CVE-2026-80968 to this issue. Affected and fixed versions =========================== Fixed in 6.12.109 with commit 036e7aa793375ab16ea0f64b8de6673220416cc1 Fixed in 6.18.50 with commit a4e774eeb61aec64da5b03d3becffde26f7fe4de Fixed in 7.2.4 with commit cf3af453a48c8d905512dfc44a5a59439b70f4f0 Fixed in 7.3-rc1 with commit d18a260720f86a5f8b5fcfefc4ba2e9dd01c10f8 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-2026-80968 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: sound/drivers/mts64.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/036e7aa793375ab16ea0f64b8de6673220416cc1 https://git.kernel.org/stable/c/a4e774eeb61aec64da5b03d3becffde26f7fe4de https://git.kernel.org/stable/c/cf3af453a48c8d905512dfc44a5a59439b70f4f0 https://git.kernel.org/stable/c/d18a260720f86a5f8b5fcfefc4ba2e9dd01c10f8
