  "details": "In the Linux kernel, the following vulnerability has been resolved:  ipv4: stop exception dump when nexthop group shrinks  Commit 4ce5dc9316de (\"inet: switch inet_dump_fib() to RCU protection\") allowed IPv4 FIB dumps to run concurrently with nexthop replacement.  fib_dump_info_fnhe() uses fib_info_num_path() as the loop bound, then fib_info_nhc() independently reloads nh-\u003enh_grp. If RTM_NEWNEXTHOP replaces a group with fewer paths between those loads, fib_info_nhc() returns NULL and the dump dereferences it through nhc_flags.  Stop the walk when the indexed path is absent. Nexthop groups are dense, so the current snapshot has no later path.",
