CVE-2026-64352

CVE-2026-64352 concerns the Linux kernel’s BPF LPM trie: sleepable BPF programs can access LPM map data due to incorrect rcu dereference checks in trie_lookup_elem/trie_update_elem/trie_delete_elem. The issue arises because trie_lookup_elem() uses rcu_dereference_check() with a condition that pas...
