CVSS 8.4 HighEPSS 0.0019 · 8th percentile

Published by the CVE Program (CNA: Linux) at 16 Sept 2026, 10:32 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. This CVE names a vendor and product rather than a package, so the lockfile check doesn’t match it.

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The ALSA harmony sound driver in the Linux kernel is affected from 2.6.12 until fixed. The interrupt handler is registered before the driver's locks are initialized, so a pending interrupt can run it with uninitialized locks; the source gives few details on attacker requirements. Upgrade to a fixed kernel such as 5.10.273, 5.15.221, 6.1.188, 6.6.157, or a later release in those series.
