CVE-2026-23259

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> io_uring/rw: free potentially allocated iovec on cache put failure<br /> <br /> If a read/write request goes through io_req_rw_cleanup() and has an<br /> allocated iovec attached and fails to put to the rw_cache, then it may<br /> end up with an unaccounted iovec pointer. Have io_rw_recycle() return<br /> whether it recycled the request or not, and use that to gauge whether to<br /> free a potential iovec or not.
