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...

kernel: svcrdma: Reject inline replies that overflow the pull-up buffer

A flaw was found in the Linux kernel's svcrdma component, which handles network communication using Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted network reply that is larger than expected. This can cause the system to write data beyond the intended memory area,...

kernel: packet: use consistent hard_header_len in non-ring send paths

An out-of-bounds write problem was observed in packetsendmsgspkt in net/packet/afpacket.c in the Linux Kernel. In this flaw, AFPACKET hardheaderlen race may allow local privilege escalation...

CVE-2026-98361

A flaw was found in the Linux kernel's RDMA over Converged Ethernet rxe driver. This flaw allows a local attacker to achieve privilege escalation by overwriting arbitrary read-only files. Missing write permission checks during On-Demand Paging ODP operations allow an unprivileged user to map memo...

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...

CVE-2026-98172

A flaw was found in the Linux kernel's Server Message Block SMB client subsystem. When establishing a Remote Direct Memory Access RDMA session, an error during session initialization can cause the cleanup routine to release the session structure without first terminating the active RDMA connectio...

CVE-2026-98359

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem. When an asynchronous RDMA port query retrieves link speed settings, the kernel fails to verify whether the associated network device is being unregistered before invoking its operations. A local user could exploit...

CVE-2026-98358

A flaw was found in the Linux kernel's iSCSI Extensions for Remote Direct Memory Access iSER driver. A remote storage target can trigger a Denial of Service DoS by sending an unexpected remote invalidation response for write operations transmitted as immediate data. In this scenario, the initiato...

kernel: RDMA/rxe: Fix OOB in free_rd_atomic_resources()

A flaw was found in the Linux kernel's RDMA/rxe component. A local user could exploit a memory corruption vulnerability in the freerdatomicresources function by updating the maxdestrdatomic value before the old array is properly freed, leading to an out-of-bounds write. This issue can cause a...

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.
