CVE-2026-53216

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the mvpp2 driver where the XDP path initializes every xdp buff with PAGE SIZE as the frame size, regardless of whether the buffer is from a short or long BM pool. Because short pool buffers can be smaller than PAGE SIZE, the bpf xdp adjust tail() function may allow a packet to grow beyond the actual memory allocation. This can lead to memory corruption or cause failures during subsequent skb tailroom checks. XDP (eXpress Data Path) is a programmable hook in the Linux kernel that allows for high-performance packet processing.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
