{"id":"DEBIAN-CVE-2025-23154","details":"In the Linux kernel, the following vulnerability has been resolved:  io_uring/net: fix io_req_post_cqe abuse by send bundle  [  114.987980][ T5313] WARNING: CPU: 6 PID: 5313 at io_uring/io_uring.c:872 io_req_post_cqe+0x12e/0x4f0 [  114.991597][ T5313] RIP: 0010:io_req_post_cqe+0x12e/0x4f0 [  115.001880][ T5313] Call Trace: [  115.002222][ T5313]  \u003cTASK\u003e [  115.007813][ T5313]  io_send+0x4fe/0x10f0 [  115.009317][ T5313]  io_issue_sqe+0x1a6/0x1740 [  115.012094][ T5313]  io_wq_submit_work+0x38b/0xed0 [  115.013223][ T5313]  io_worker_handle_work+0x62a/0x1600 [  115.013876][ T5313]  io_wq_worker+0x34f/0xdf0  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.","modified":"2026-08-27T23:05:27.439138491Z","published":"2025-05-01T13:15:51.310Z","upstream":["CVE-2025-23154"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-23154"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.25-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-23154.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.25-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-23154.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
