An update for alsa-lib is now available for HCE 3.0 Security Advisory hws_security@huawei.com Huawei Cloud HCE3-SA-2026-0001 Final 1.0 1.0 2026-03-02T12:28:38:00Z current version 2026-03-02T12:28:38:00Z 2026-03-02T12:28:38:00Z HCE SA Engine 1.0.0 An update for alsa-lib is now available for HCE 3.0 HCE Security has rated this update as having a security impact of Moderate.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section. Security Fix(es): alsa-lib versions 1.2.2 up to and including 1.2.15.2, prior to commit 5f7fe33, contain a heap-based buffer overflow in the topology mixer control decoder. The tplg_decode_control_mixer1() function reads the num_channels field from untrusted .tplg data and uses it as a loop bound without validating it against the fixed-size channel array (SND_TPLG_MAX_CHAN). A crafted topology file with an excessive num_channels value can cause out-of-bounds heap writes, leading to a crash.
