CVE-2026-96674

alsa-lib through 1.2.16.1 Integer Overflow via Topology File

Published Sep 23, 2026 CVSS 4.0 · 4.8 Medium EPSS < 1% KEV · Not listed
Description
alsa-lib through 1.2.16.1 computes combined topology element size using 32-bit arithmetic in src/topology/ctl.c, allowing integer overflow that defeats bounds checks. Attackers can supply crafted topology files that wrap size calculations, causing the decoder to read beyond the topology buffer and potentially leak sensitive data or crash the application.
