A vulnerability in the Linux kernel's mlx5e driver related to XDP redirect to AF_XDP sockets could cause stale buffer pointers to be freed twice, leading to double publication of UMEM frames. This occurs when the RX ring is full and a refill retry partially succeeds, leaving some WQEs with stale buffer pointers. The issue was detected with high packet rates and causes silent failures without kernel warnings. A fix has been implemented to mark WQEs as released immediately after freeing buffers, preventing double free and stale pointer use.
