Astra Linux – vulnerability in linux, linux-5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Return CQE error if invalid lkey was supplied RXE fails to update the WQE status in cases where LOCALWRITE fails. This resulted in the following kernel panic when an atomic operation was performed using an explicitly...

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...

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-2026-46325

Summary (details from sources): CVE-2026-46325 affects the Linux kernel RDMA/rxe code, where iova-to-va conversion fails when MR page_size differs from system PAGE_SIZE. The bug arises because rxe_set_page() uses mr->page_size steps while the page_list holds PAGE_SIZE pages, and ib_sg_to_page(...
