From: Greg Kroah-Hartman <[email protected]> Description =========== In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: pcm512x: fix null-ptr dereference in pcm512x_overclock_xxx_put() In the pcm512x chipset driver, pcm512x_overclock_xxx_put() is defined as a general mixer kcontrol instead of a DAPM kcontrol, so struct snd_soc_dapm_context must not be accessed via snd_soc_dapm_kcontrol_to_dapm(). This causes a NULL pointer dereference, so it must be modified to use snd_soc_component_to_dapm(). The Linux kernel CVE team has assigned CVE-2026-64107 to this issue. Affected and fixed versions =========================== Issue introduced in 6.19 with commit 02dbbb7e982a6873f81e69e4fef59a42decb7b1a and fixed in 7.0.11 with commit 285159ca199cbbe424223d4b14db227b279b5767 Issue introduced in 6.19 with commit 02dbbb7e982a6873f81e69e4fef59a42decb7b1a and fixed in 7.1 with commit 09e8f9a9aa19aa8c1b0cc7a0ebc68f6ecf86a660 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-2026-64107 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/soc/codecs/pcm512x.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/285159ca199cbbe424223d4b14db227b279b5767 https://git.kernel.org/stable/c/09e8f9a9aa19aa8c1b0cc7a0ebc68f6ecf86a660
