{"id":"DEBIAN-CVE-2023-54089","details":"In the Linux kernel, the following vulnerability has been resolved:  virtio_pmem: add the missing REQ_OP_WRITE for flush bio  When doing mkfs.xfs on a pmem device, the following warning was   ------------[ cut here ]------------  WARNING: CPU: 2 PID: 384 at block/blk-core.c:751 submit_bio_noacct  Modules linked in:  CPU: 2 PID: 384 Comm: mkfs.xfs Not tainted 6.4.0-rc7+ #154  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)  RIP: 0010:submit_bio_noacct+0x340/0x520  ......

Simply fix it by adding the missing REQ_OP_WRITE for flush bio. And we could fix the flush order issue and do flush optimization later.","modified":"2026-09-15T08:47:26.012342035Z","published":"2025-12-24T13:16:10.767Z","upstream":["CVE-2023-54089"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54089"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.5.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54089.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.5.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54089.json"}}],"schema_version":"1.9.0"}
