CVE-2026-43090

CVE-2026-43090 concerns a Linux kernel memory-leak in the XFRM subsystem. The root cause is a double call to xfrm_pol_hold_rcu() inside xfrm_migrate_policy_find(), even though the lookup function already returns a policy with a held reference. This leads to a refcount imbalance and memory leak of...
