CVE-2026-68183

System crash via resource leaks and list corruption

Published Aug 10, 2026 · Updated Aug 10, 2026

Resource-management flaws in the Linux kernel allow local users to crash systems using Intel Stratix 10 service firmware. Failed gen_pool_alloc() paths leak pmem, devm-managed allocation outlives list-managed objects, and an invalid list_del() corrupts the service-memory list on failed lookups. Reachability requires local low-privileged access and an Intel Stratix 10 system using the service driver; the bounded impact is system instability or a crash.
