CVE-2026-68198

The CVE-2026-68198 issue affects the Linux kernel’s ath6kl Wi‑Fi driver, specifically aggr_reset_state(). The non-synchronous timer deletion (timer_delete) can race with timer callbacks (aggr_timeout) that access aggr_conn fields, potentially freeing memory used by the callback, leading to a use‑...

CVE-2026-68129

CVE-2026-68129 concerns the Linux kernel gve driver. Under extreme memory pressure, Rx buffer allocations can fail during the receive (Rx) buffer refill loop, causing the number of buffers posted to hardware to drop below a critical threshold and leading to a permanent queue stall. Consequences d...
