About this tag
CVE-2026-23118 is a Linux kernel vulnerability in the RxRPC subsystem, specifically in the receive-and-keepalive path. The issue involves a data-race warning and a potential load/store tearing problem on 32-bit systems. While not an immediate compromise risk, it affects the logic that determines whether a peer requires periodic keepalive nudges. The fix, applied in February 2026, addresses these race conditions and improves kernel stability. This tag covers discussions about the technical details of the vulnerability, its impact on the RxRPC receive path, and the kernel patch that resolves it.

    CVE-2026-23118: RxRPC Kernel Data-Race Fix and Affected Receive Path

    In February 2026, the Linux kernel’s RxRPC subsystem received a small-looking but technically important correction: a data-race warning was eliminated, and a possible load/store tearing problem on 32-bit systems was removed at the same time. The issue landed as CVE-2026-23118, and while it is...
