CVE-2026-25068  (opens in a new tab)
CWE-129  (opens in a new tab)

How to fix?

There is no fixed version for libalsa.

Overview

Affected versions of this package are vulnerable to Improper Validation of Array Index in the tplg_decode_control_mixer1() function when the num_channels field from untrusted .tplg data is used as a loop bound without validation against the fixed-size channel array. An attacker can cause out-of-bounds heap writes and potentially crash the application by supplying a crafted topology file with an excessive num_channels value.
