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...

CVE-2026-72023

A flaw was found in the Linux kernel's octeontx2-pf driver. During the initialization of hardware resources, a memory leak occurs where certain pointer arrays are not properly freed upon failure. This issue could lead to resource exhaustion, potentially resulting in a Denial of Service DoS for th...
