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: 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...
