CVE-2026-53250

Linux kernel vulnerability CVE-2026-53250 in the xsk path (xsk_skb_metadata) allowed a race between reads of csum_start and csum_offset from shared UMEM memory, letting a malicious userspace overwrite values between validation and skb assignment. The fix caches csum_start and csum_offset in local...

CVE-2026-53229

The CVE-2026-53229 entries describe a Linux kernel issue in the mlx5e_xmit_xdp_buff() path of the net/mlx5e driver (XSK/XDP_TX). When sq->xmit_xdp_frame() returns false (e.g., XDPSQ full), the code returns without unmapping the DMA address or freeing the xdp_frame. The DMAAPI debug trace can s...
