CVE-2026-90292

CVE-2026-90292 is a use-after-free in the Linux kernel's RDMA/siw subsystem, specifically in siw_accept() . When a QP supplied by userspace is already in the RTS state, the error cleanup path incorrectly drops a reference from the incoming CEP rather than the existing qp->cep, potentially free...

CVE-2026-90292 RDMA/siw: Fix use-after-free in siw_accept()

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fix use-after-free in siwaccept siwaccept looks up the QP supplied by userspace. If that QP is already in RTS, the function jumps to error cleanup before associating the incoming CEP with it. The cleanup tests whether...

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...
