CVE-2026-53216
Description
A flaw was found in the Linux kernel's mvpp2 network driver. This vulnerability arises from improper handling of the eXpress Data Path (XDP) frame size, where the system advertises a larger frame size than the actual allocated buffer for short buffer pools. This can allow the bpf_xdp_adjust_tail() function to write data beyond the intended memory boundary, leading to memory corruption. Such corruption could potentially result in system instability or denial of service.
Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
