CVE-2026-80946

This Linux kernel vulnerability affects the FUSE-io-uring transport. The fuse_request slab cache (fuse_req_cachep) is created without a usercopy whitelist , so directly copying req->in.h to the ring or req->out.h back from the ring trips CONFIG_HARDENED_USERCOPY , triggering a kernel panic ...

CVE-2026-80939

CVE-2026-80939 affects the Linux kernel rtw89 PCI WiFi driver on arm64 platforms. The root cause is a missing .shutdown callback: during warm reboot the kernel invokes device_shutdown() but not .remove(), so the rfkill polling workqueue continues issuing MMIO reads to the PCI device after the PCI...
