"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxsk: Use a 32-bit compare in xsk_map_gen_lookup\n\nxsk_map_gen_lookup() loads a u32 key and compares it with max_entries\nusing BPF_JMP_IMM. BPF immediates are sign-extended to 64 bits, so a\nmax_entries value of 0x80000000 or higher becomes a threshold larger\nthan every zero-extended 32-bit key. An out-of-range index then skips\nthe bounds check and the generated lookup reads past xsk_map[].\n\nCompare with BPF_JMP32_IMM so the check stays in 32-bit unsigned range."
