CVE-2024-42082 is a Linux kernel XDP issue in __xdp_reg_mem_model() in net/core/xdp.c. The function used WARN() when __mem_id_init_hash_table() returned an error during XDP memory-model registration. The error condition is reachable when memory allocation fails; the alternative rhashtable initialization error path is not expected because the code uses valid static rhashtable parameters. The kernel fix removes the unnecessary WARN() handling.
