Linux Kernel Memory Leak Vulnerability in IDPF VPort Release Function

A memory leak vulnerability has been identified in the Linux kernel's Intel IDPF driver. The issue arises in the 'idpf_vport_rel' function, where the 'rx_ptype_lkup' pointer is not properly freed during a reset, leading to unreferenced memory. This vulnerability affects the Linux kernel stable tree.

Impact

Exploitation of this vulnerability leads to a memory leak, where allocated memory is not properly released, potentially causing increased memory usage and degradation of system performance over time.

Remediation

Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit fixing this issue is available in the Linux kernel stable tree.
