{"id":"DEBIAN-CVE-2023-54235","details":"In the Linux kernel, the following vulnerability has been resolved:  PCI/DOE: Fix destroy_work_on_stack() race  The following debug object splat was observed in testing:    ODEBUG: free active (active state 0) object: 0000000097d23782 object type: work_struct hint: doe_statemachine_work+0x0/0x510   WARNING: CPU: 1 PID: 71 at lib/debugobjects.c:514 debug_print_object+0x7d/0xb0   ...   Workqueue: pci 0000:36:00.0 DOE [1 doe_statemachine_work   RIP: 0010:debug_print_object+0x7d/0xb0   ...   Call Trace:    ? debug_print_object+0x7d/0xb0    ? __pfx_doe_statemachine_work+0x10/0x10    debug_object_free.part.0+0x11b/0x150    doe_statemachine_work+0x45e/0x510    process_one_work+0x1d4/0x3c0  This occurs because destroy_work_on_stack() was called after signaling the completion in the calling thread.  This creates a race between destroy_work_on_stack() and the task-\u003ework struct going out of scope in pci_doe().  Signal the work complete after destroying the work struct.  This is safe because signal_task_complete() is the final thing the work item does and the workqueue code is careful not to access the work struct after.","modified":"2026-09-15T08:47:52.402532366Z","published":"2025-12-30T13:16:11.953Z","upstream":["CVE-2023-54235"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54235"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.55-1"}]}],"versions":["6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1","6.1.52-1","6.1.55-1~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54235.json"}},{"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-2023-54235.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-2023-54235.json"}}],"schema_version":"1.9.0"}
