CVE-2026-23419

CVE-2026-23419 affects the Linux kernel’ s RDS implementation. The issue is a circular locking dependency in net/rds: a memory allocation performed inside the socket lock during the call to sk_net_refcnt_upgrade() creates a deadlock with fs_reclaim. The root cause is that sk_net_refcnt_upgrade() ...

kernel: Linux kernel: Use-after-free in BPF sockmap can lead to denial of service and privilege escalation

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap subsystem. A race condition exists where the sksocket is not properly locked or referenced during the skbsendsock function call, allowing for a use-after-free vulnerability. This can be exploited by a local attacker, leadin...
