CVE-2026-96674 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. 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.. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
