CVE-2026-93154

A flaw was found in the Linux kernel's RDMA/irdma component. This vulnerability allows a local user to deregister Memory Regions MRs that are actively backing Queue Pair QP, Completion Queue CQ, and Shared Receive Queue SRQ rings. By doing so, a malicious user could potentially disrupt network...

Astra Linux – vulnerability in linux-6.1, linux-6.12

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Initialize freeqp completion before using it In irdmacreateqp, if ibcopytoudata fails, it will call irdmadestroyqp to clean up which will attempt to wait on the freeqp completion, which is not initialized yet. Fix thi...

Astra Linux – vulnerability in linux-5.10, linux-5.15, linux

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix error unwind in rxecreateqp In the function rxecreateqp, rxeqpfrominit is called to initialize the qp; however, internal components such as spin locks are not set up until rxeqpinitreq is executed. If an error occur...

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Return the firmware result upon destroying QP/RQ Previously, when a QP/RQ was destroyed, the result returned by the firmware destruction function was ignored, and higher layers were not informed of the failure. This...

Astra Linux - vulnerability in linux

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Clear all QP fields if creation failed rxeqpdocleanup relies on valid pointer values in QP for properly created ones; however, if rxeqpfrominit fails, those fields are filled with garbage, leading to the following error...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/irdma: Fixed a data race on the CQP request done field. KCSAN detected a data race in the cqprequest-requestdone memory location. This location is accessed without a lock in the irdmahandlecqpop function, while it is bein...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix mlx5pollone curqp update flow When curqp is not NULL, to avoid re-fetching the QP from the radix tree, we check whether the next CQE QP matches the one we already have. However, the bug lies in the fact that we...

CVE-2026-97477

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem. An error-handling issue during counter allocation and queue pair binding neglects to decrement the active counter tally when a bind attempt fails. A local user can exploit this flaw by triggering repeated binding...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/rxe: Fixed the “kernel NULL pointer dereference” error. When the rxequeueinit function in the rxeqpinitreq function fails, both qp-req.task.func and qp-req.task.arg are not initialized. Due to the failure in creating the...

Linux Distros Unpatched Vulnerability : CVE-2026-80864

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - RDMA/rxe: Fix responder UAF on IBQPMAXDESTRDATOMIC modifyqp rxeqpfromattr handles IBQPMAXDESTRDATOMIC outside the IBQPSTATE path, so it holds no statelock and...

CVE-2026-68418

A flaw was found in the RDMA/irdma component of the Linux kernel. A local user could exploit this vulnerability by providing a zero value for userwqebufs during the creation of a Queue Pair QP. This action leads to a null pointer dereference, which can cause the system to crash, resulting in a...

CVE-2026-68417

A flaw was found in the Linux kernel's RDMA/siw component. The siwcreateqp function prematurely publishes a Queue Pair QP before its complete initialization. This allows a Queue Pair Number QPN lookup to access a QP that is still under construction, potentially leading to unexpected behavior or...

CVE-2026-68418

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp-iwpbl if the user-provided req.userwqebufs field was non-zero. The problem is that iwqp-iwpbl is...

CVE-2026-68417

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

EUVD-2026-55604

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp-iwpbl if the user-provided req.userwqebufs field was non-zero. The problem is that iwqp-iwpbl is...

CVE-2026-68418 RDMA/irdma: Prevent user-triggered null deref on QP create

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp-iwpbl if the user-provided req.userwqebufs field was non-zero. The problem is that iwqp-iwpbl is...

CVE-2026-68418

CVE-2026-68418 affects the Linux kernel RDMA/irdma path, specifically QP creation. The root cause was that iwqp->iwpbl could be dereferenced unconditionally later in irdma_setup_virt_qp if a user supplied req.user_wqe_bufs, even when it was zero. Although there was a NULL check, it only applie...

CVE-2026-68417 RDMA/siw: publish QP after initialization

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

CVE-2026-68417

The CVE-2026-68417 issue affects the Linux kernel RDMA/siw component. Root cause: siw_create_qp() calls siw_qp_add() before QP state/queues/CQs/completion/device list are fully initialized, allowing a QPN lookup to reach a QP still under construction.
