CVE-2026-64222

A flaw was found in the Linux kernel's octeontx2-pf driver. This vulnerability involves a double free of memory during the initialization of the Accelerated Queue AQ when an error occurs. Specifically, the pool-stack memory is freed twice, which can lead to memory corruption. A local attacker cou...
