CVE-2026-80946

In the Linux kernel, the following vulnerability has been resolved: fuse: copy request headers via a stack buffer for io-uring The fuse-io-uring transport copies req-in.h out to the ring in fuseuringcopytoring and req-out.h back in fuseuringcommit. Both headers live inside the fuserequest slab...

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-2025-68791

A reference count leak flaw was found in the Linux kernel's FUSE filesystem when using iouring for argument copies. The copyfinish function is not called in error paths, causing page reference counts to leak. This can lead to memory being pinned indefinitely and potential resource exhaustion...

In the Linux kernel, the following vulnerability has been resolved: fuse: missing copyfinish in fuse-over-io-uring argument copies Fix a possible reference count leak of payload pages during fuse argument copies. Joanne: simplified error cleanup...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the lack of copyfinish in the copy of fuse-over-io-uring parameter, which could lead to a reference count le...
