CVE-2026-64258

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fuse-uring: remove request-less entries from ent_w_req_queue to fix NULL deref<br /> <br /> If a copy into the userspace ring buffer fails, a request will be<br /> terminated and fuse_uring_req_end() will set ent-&gt;fuse_req to NULL but<br /> it will leave the entry on ent_w_req_queue in FRRS_FUSE_REQ state. This<br /> can lead to a NULL deref if the request expiration logic scans<br /> ent_w_req_queue in the window before the entry is moved off it.<br /> <br /> Fix this by taking the entry off ent_w_req_queue and changing its state<br /> from FRRS_FUSE_REQ to FRRS_INVALID before terminating the request.
