This fixes out-of-bounds slab read accesses made by memcpy() of the hdmi-codec driver. This problem is reported by KASAN. The Linux kernel CVE team has assigned CVE-2022-48739 to this issue. Affected and fixed versions =========================== Fixed in 5.15.22 with commit 10007bd96b6c Fixed in 5.16.8 with commit 1552e66be325 Fixed in 5.17 with commit 06feec6005c9 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-2022-48739 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: include/uapi/sound/asound.h sound/soc/codecs/hdmi-codec.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/10007bd96b6c4c3cfaea9e76c311b06a07a5e260 https://git.kernel.org/stable/c/1552e66be325a21d7eff49f46013fb402165a0ac https://git.kernel.org/stable/c/06feec6005c9d9500cd286ec440aabf8b2ddd94d
