CVE-2026-74563
A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS TCP module. The rdstcpladdrcheck function fails to hold the Read-Copy-Update RCU lock across an IPv6 address check. This allows a race condition where a network device can be freed while still being referenced, leading to a...
CVE-2026-74563 rds: tcp: hold the RCU lock across ipv6_chk_addr() in rds_tcp_laddr_check()
In the Linux kernel, the following vulnerability has been resolved: rds: tcp: hold the RCU lock across ipv6chkaddr in rdstcpladdrcheck rdstcpladdrcheck looks up a scoped IPv6 interface with devgetbyindexrcu, drops the RCU read-side lock, and only then passes the bare struct netdevice into...

CVE-2026-68290
A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS TCP implementation. A race condition can occur during network namespace teardown, where a concurrent system control sysctl write operation attempts to access a socket that has already been freed. This use-after-free vulnerabilit...

CVE-2026-68290
CVE-2026-68290 concerns the Linux kernel RDS TCP implementation. A race condition during network namespace teardown can occur when a concurrent sysctl write dereferences a freed per-netns listen socket, due to rds_tcp_exit_net() freeing the socket before the per-netns sysctl table is unregistered...
