In the Linux kernel, the following vulnerability has been resolved: xfrm: move policy_bydst RCU sync from per-netns .exit to .pre_exit The struct… (CVE-2026-64525)CVE-2026-64525 0 A vulnerability in the Linux kernel's xfrm subsystem related to improper handling of RCU synchronization during network namespace cleanup has been resolved. The issue involved calling synchronize_rcu() in the .exit handler of pernet_operations, which can cause excessive blocking and resource accumulation during cleanup of multiple network namespaces. The fix moves the RCU synchronization to the .pre_exit handler, improving cleanup efficiency and preventing memory exhaustion under heavy workload. No known exploits are reported.
