If all entries are initialised, the loop reads past the end of the array. Pass the allocated entry count to create_sdw_dailinks() and stop before reading past the array. The Linux kernel CVE team has assigned CVE-2026-74332 to this issue.

Affected files ============== The file(s) affected by this issue are: sound/soc/amd/acp/acp-sdw-sof-mach.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/0a5ff4000dd7a390139dd7823fef1de4963e490a https://git.kernel.org/stable/c/9e82497138abea7d5c6e65015663d907fbcbf6b4 https://git.kernel.org/stable/c/86a64c049873fe4d4a6a378e27a333ab5631c4b2 https://git.kernel.org/stable/c/4d992e63f52d58f52b724606c60ae7b37a1c582f
