CVE-2026-45910

The CVE-2026-45910 issue affects the Linux kernel RDMA/rxe driver, caused by a race between retransmit_timer() and rxe_destroy_qp that can drop a Queue Pair (QP) reference count to zero during timer handling. Public documents describe a use-after-free risk and refcount underflow in affected flows...

CVE-2025-39955

The CVE-2025-39955 entry concerns the Linux kernel TCP Fast Open path. The root cause is that tcp_disconnect() failed to clear tcp_sk(sk)->fastopen_rsk, allowing the retransmit timer to trigger while a TFO socket is being reused, potentially delaying or missing a retransmission. The fix implem...

kernel: tcp: avoid too many retransmit packets

A vulnerability was found in the tcpretransmittimer function in the Linux kernel's TCP implementation. This issue occurs when a TCP socket uses TCPUSERTIMEOUT and the peer's window retracts to zero, leading to excessive retransmission of packets every two milliseconds for up to four minutes after...
