Description

This security bulletin contains information about 1 vulnerability.


1) Memory corruption (CVE-ID: CVE-2026-98272)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to corrupt memory.

The vulnerability exists due to a buffer overflow in the mvpp2 driver's page_pool array during mvpp2_bm_init() when changing the network interface MTU triggers a switch to per-CPU buffering without checking the pool count. A local user can trigger this buffering switch with a receive-queue configuration that exceeds the array capacity to corrupt memory.

The per-CPU buffering scheme requires two pools per receive queue and supports a maximum of eight pools.
