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() ...
