Fix this by: 1. Changing clk_get() to the device-managed devm_clk_get(). 2. Adding proper IS_ERR() checks for both clock acquisitions. The Linux kernel CVE team has assigned CVE-2026-43480 to this issue.

Affected files ============== The file(s) affected by this issue are: sound/soc/amd/acp3x-rt5682-max9836.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/2dc43ac8da7b2bebc5a51a3d86a6275d78f27cff https://git.kernel.org/stable/c/4d802f23fcbfec05134653fd001f6c7c3fd55196 https://git.kernel.org/stable/c/2b0c4a399c8d27f20ecf17dda76751141d6dbb59 https://git.kernel.org/stable/c/35c7624d30cb45ec336cd16ce072acc32ae351cb https://git.kernel.org/stable/c/33de168afdd57265a0e0c20dbd3648a2d8f7cdc4 https://git.kernel.org/stable/c/790851ecc983c719fa2e6adb17b02f3acc1d217d https://git.kernel.org/stable/c/092522621901b5e6af61db04a53f5b313903c6d0 https://git.kernel.org/stable/c/53f3a900e9a383d47af7253076e19f510c5708d0
