CVE-2026-98374 tcp: fix use-after-free of retransmit_skb_hint in tcp_send_synack()

In the Linux kernel, the following vulnerability has been resolved: tcp: fix use-after-free of retransmitskbhint in tcpsendsynack When tcpsendsynack replaces the cloned SYN skb at the head of the retransmit queue with a copy, it frees the original with tcprtxqueueunlinkandfree and only repairs...

CVE-2026-98374

The Linux kernel is vulnerable to a use-after-free flaw in the tcp_send_synack() function. The issue occurs because the function frees the original cloned SYN skb using tcp_rtx_queue_unlink_and_free() but fails to update tp->retransmit_skb_hint, which continues to point at the freed skbuff_fcl...

kernel: vsock/vmci: fix UAF when peer resets connection during handshake

A flaw was found in the vsock/vmci component of the Linux kernel. A remote attacker could exploit a Use-After-Free UAF vulnerability when a peer resets a connection during the handshake process. This occurs because the system incorrectly handles reset packets, leading to a pending socket being le...

CVE-2026-98360

A flaw was found in the Linux kernel's Remote Direct Memory Access over Converged Ethernet RDMA/rxe driver. A local user can trigger a Denial of Service DoS or system crash by attempting to attach to a multicast group when network device operations fail. In this scenario, improper error handling...

kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...

kernel: RDMA/rxe: Fix a use-after-free problem in rxe_mmap

A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...

An update for kernel is now available for Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions and Red Hat Enterprise Linux 8.8 Telecommunications Update Service. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring Syst...

kernel: smc: Fix use-after-free in tcp_write_timer_handler()

In the Linux kernel, the following vulnerability has been resolved: smc: Fix use-after-free in tcpwritetimerhandler. With Eric's ref tracker, syzbot finally found a repro for use-after-free in tcpwritetimerhandler by kernel TCP sockets. 0 If SMC creates a kernel socket in smccreate, the kernel...

kernel: sctp: purge outqueue on stale COOKIE-ECHO handling

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability, a use-after-free, occurs when the system processes a Stale Cookie ERROR during the setup or reconfiguration of an SCTP association. A remote attacker could exploit this by sending...

kernel: xfrm: policy: fix use-after-free on inexact bin in xfrm_policy_bysel_ctx()

A flaw was found in the Linux kernel. A race condition exists in the xfrm policy handling, specifically within the xfrmpolicybyselctx function. This flaw allows for a use-after-free vulnerability, where memory is accessed after it has been released. This can lead to system instability or a denial...

kernel: xfrm: input: hold netns during deferred transport reinjection

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...

kernel: RDMA/rxe: Fix responder UAF on IB_QP_MAX_DEST_RD_ATOMIC modify_qp

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe component. A local, unprivileged user could exploit a race condition during a queue pair modification operation. This could lead to a use-after-free vulnerability, allowing the attacker ...

kernel: netfilter: flowtable: publish GC-visible tuple last

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

CVE-2026-98357
