Linux Kernel CVE-2026-43295

Apply vendor-released kernel patch from the stable Linux tree corresponding to your kernel version: upgrade to Linux 5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, or 7.0 (or later), as appropriate for your branch. The fix is available at kernel commits referenced in https://git.kernel.org/stable/. For distributions: update the kernel package through your package manager (apt update && apt upgrade linux-image-*, yum update kernel, etc.). If immediate patching is not feasible, mitigation via configuration is possible on systems where RapidIO hardware is not in use: disable the RapidIO subsystem at compile time (CONFIG_RAPIDIO=n) or unbind the rio-scan driver at runtime. Note that this eliminates RapidIO functionality entirely, suitable only for environments without RapidIO interconnect hardware.
