Use-after-free in Linux kernel - CVE-2026-53215

Vulnerability identifier: #VU135561

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-53215

CWE-ID: CWE-416

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to a use-after-free in the mvpp2 RX buffer handling in drivers/net/ethernet/marvell/mvpp2/mvpp2_main.c when processing received packets through XDP or skb paths. A local attacker can trigger packet processing that returns a retired buffer to the BM pool to cause a denial of service.

Hardware may DMA into memory that is no longer owned by the RX ring after the buffer has been recycled, redirected, queued for XDP_TX, or freed.
