This could lead to a kernel crash when the invalid pointers are later dereferenced by clock core functions. Fix this by: 1. Changing clk_get() to the device-managed devm_clk_get(). 2. Adding IS_ERR() checks immediately after each clock acquisition. The Linux kernel CVE team has assigned CVE-2026-43443 to this issue. Affected and fixed versions =========================== Issue introduced in 5.16 with commit d4c750f2c7d44b5b39e197308bc3f510205bba4b and fixed in 6.19.9 with commit 0cee68fb7f4cf1562e067c5a82d25062a973b0d0 Issue introduced in 5.16 with commit d4c750f2c7d44b5b39e197308bc3f510205bba4b and fixed in 7.0 with commit 30c64fb9839949f085c8eb55b979cbd8a4c51f00 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-2026-43443 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/amd/acp/acp-mach-common.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/0cee68fb7f4cf1562e067c5a82d25062a973b0d0 https://git.kernel.org/stable/c/30c64fb9839949f085c8eb55b979cbd8a4c51f00
