CVE-2026-74698

A flaw was found in the Linux kernel's net/mlx5e driver. When a Send Queue SQ is re-activated, the Byte Queue Limits BQL counters are incorrectly reset even if there are still network transmissions in progress. This can lead to an inconsistent state, causing the kernel to trigger an error and...

CVE-2026-72448

A flaw was found in the octeontx2-pf driver in the Linux kernel. When a network interface utilizing this driver is shut down or the device is removed, a memory leak occurs because the send-queue timestamp buffer is not properly deallocated. This continuous memory accumulation can lead to system...
