If all entries are initialised, the loop reads past the end of the array. This was reported by KASAN: BUG: KASAN: slab-out-of-bounds in mc_probe+0x26b3/0x2774 [snd_acp_sdw_legacy_mach] Read of size 1 Pass the allocated entry count to create_sdw_dailinks() and stop before reading past the array. The Linux kernel CVE team has assigned CVE-2026-74333 to this issue.

Affected files ============== The file(s) affected by this issue are: sound/soc/amd/acp/acp-sdw-legacy-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/1279bdab5fa1f28c168e54215db506e87c6fac1e https://git.kernel.org/stable/c/0230471eef5902207516851dcd47c559571dded2 https://git.kernel.org/stable/c/d49ecdf327cc91062d2f80996a163cf65fda1e60
