CVE-2025-23154
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
io_uring/net: fix io_req_post_cqe abuse by send bundle
As the comment states, io_req_post_cqe() should only be used by multishot requests, i.e. REQ_F_APOLL_MULTISHOT, which bundled sends are not. Add a flag signifying whether a request wants to post multiple CQEs. Eventually REQ_F_APOLL_MULTISHOT should imply the new flag, but that's left out for simplicity.
