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...
