Linux Distros Unpatched Vulnerability : CVE-2026-80910

critical Nessus Plugin ID 342968

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - ASoC: codecs: lpass-wsa-macro: Fix enum kcontrol accesses EAR SPKR PA Gain and the four WSA RX* Mux controls are enumerated, but their get and put callbacks access the value through ucontrol->value.integer.value[0] (a long) instead of ucontrol->value.enumerated.item[0] (an unsigned int).
 This same pattern was fixed in the sibling drivers by commit bcfe5f76cc40 (ASoC: codecs: rx-macro: fix accessing array out of bounds for enum type) and commit 0ea5eff7c606 (ASoC: codecs: va-macro: fix accessing array out of bounds for enum type), but wsa-macro was missed. On 64-bit kernels with CONFIG_SND_CTL_DEBUG this trips the elem value sanity check and every read of these controls fails with
 -EINVAL. (CVE-2026-80910)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
