"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipv4: stop exception dump when nexthop group shrinks\n\nCommit 4ce5dc9316de (\"inet: switch inet_dump_fib() to RCU\nprotection\") allowed IPv4 FIB dumps to run concurrently with nexthop\nreplacement.\n\nfib_dump_info_fnhe() uses fib_info_num_path() as the loop bound,\nthen fib_info_nhc() independently reloads nh->nh_grp. If\nRTM_NEWNEXTHOP replaces a group with fewer paths between those loads,\nfib_info_nhc() returns NULL and the dump dereferences it through\nnhc_flags.\n\nStop the walk when the indexed path is absent. Nexthop groups are\ndense, so the current snapshot has no later path."
