CVE-2026-53211

In the Linux kernel fix for CVE-2026-53211, the vulnerability stems from netfilter nft_meta_bridge where NFT_META_BRI_IIFHWADDR declares a 6-byte destination register, which is rounded up to two 32-bit registers (8 bytes). nft_meta_bridge_get_eval() performs memcpy(dest, br_dev->dev_addr, ETH_...

CVE-2026-53148

In the Linux kernel Thunderbolt code, tb_xdp_properties_request derives per-packet copy length from the response header and may exceed the previously allocated data buffer, allowing memcpy to write past the kcalloc allocation. The fix clamps the per-packet copy length so that the cumulative offse...
