CVE-2022-50066

Kernel crash via atlantic loop overrun

Published Jun 18, 2025 · Updated May 11, 2026

An out-of-bounds access in the Linux kernel allows local users to crash the system during atlantic network-driver suspension. The aq_nic_stop loop advances its index and dereferences self->aq_vec[i] after the final valid array element, reaching index 8 in an eight-entry array. Reachability requires local low-privileged access, the atlantic driver, and its suspension path; the reported consequence is an availability-only kernel crash.
