CVE-2026-98367

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA Soft-iWARP siw driver. A race condition occurs during connection handling if modifying a queue pair fails, releasing an internal lock before error cleanup completes. A local attacker could exploit this timing window through...

CVE-2026-98366

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA software driver. A local user can exploit this vulnerability to cause a Denial of Service DoS or potentially gain elevated privileges by triggering a use-after-free memory flaw. This issue occurs because the driver updates...

CVE-2026-98365

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA software driver. An unauthenticated remote attacker can cause a Denial of Service DoS or out-of-bounds memory access by sending specially crafted network requests that trigger an integer overflow during memory range validatio...

kernel: RDMA/rxe: Reject non-8-byte ATOMIC_WRITE payloads

A flaw was found in the Linux kernel's RDMA Remote Direct Memory Access subsystem, specifically within the rxe driver. A remote attacker could exploit this vulnerability by sending a specially crafted ATOMICWRITE request with a zero-byte payload. This improper handling of non-8-byte ATOMICWRITE...

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: 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: 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...

kernel: RDMA/rxe: Fix race condition in QP timer handlers

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA RXE component. A race condition exists between the retransmittimer and rxedestroyqp functions. This can cause a Queue Pair QP reference count to underflow, leading to a use-after-free vulnerability. A local attacker could...

kernel: RDMA/rxe: Reject unknown opcodes before ICRC processing

A flaw was found in the Linux kernel's Soft RoCE RDMA/rxe driver. An unauthenticated remote attacker can send a specially crafted UDP packet with an unknown opcode to trigger an out-of-bounds read. This vulnerability can lead to a kernel panic, effectively causing a Denial of Service DoS on the...

kernel: RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv

A flaw was found in the Linux kernel's RDMA/rxe component. The rxercv function does not adequately validate the BTH pad and ICRC fields of incoming packets before calculating the payload size. A remote attacker could exploit this by sending a specially crafted short packet or a packet with a forg...
