In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix out-of-bounds write in irdmacopyuserpgaddrs The irdmacopyuserpgaddrs function loops through all of the umem DMA blocks to populate the PBLEs and will stop when either the last DMA block is reached or palloc-totalc...

CVE-2026-74390

CVE-2026-74390 affects the Linux kernel’s RDMA/irdma path. The vulnerability stems from an out-of-bounds write in irdma_copy_user_pgaddrs, which iterates over umem DMA blocks to fill PBLEs. When irdma_setup_pbles is called with lvl==0, the loop may not exit properly if palloc->total_cnt == 0, ...

CVE-2026-74346

CVE-2026-74346 pertains to the Linux kernel RDMA/irdma subsystem, fixing an OOB read during CQ MR registration. The root cause was that the cqmr->split field, which indicates IRDMA_FEATURE_CQ_RESIZE, was not reliably set at MR registration time. The fix eliminates the cqmr->split field and ...

CVE-2026-72494

CVE-2026-72494 : In the Linux kernel RDMA/irdma driver, a synchronization issue was resolved by replacing a waitqueue plus request_done flag (lacked proper memory barriers) with a completion primitive designed for this purpose. The change removes the explicit flag and barriers, relying on the com...

EUVD-2026-55605

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent reregmr for non-mem regions When a QP/CQ/SRQ is created, a two step process is used where the buffer is allocated in userspace and explicitly registered with the normal regmr mechanism prior to creating the...

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...

Astra Linux – Vulnerability in Linux 5.10

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. This process will attempt to wait for the freeqp completion, but freeqp has not yet been...
