{"id":"CVE-2023-54235","summary":"PCI/DOE: Fix destroy_work_on_stack() race","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nPCI/DOE: Fix destroy_work_on_stack() race\n\nThe following debug object splat was observed in testing:\n\n  ODEBUG: free active (active state 0) object: 0000000097d23782 object type: work_struct hint: doe_statemachine_work+0x0/0x510\n  WARNING: CPU: 1 PID: 71 at lib/debugobjects.c:514 debug_print_object+0x7d/0xb0\n  ...\n  Workqueue: pci 0000:36:00.0 DOE [1 doe_statemachine_work\n  RIP: 0010:debug_print_object+0x7d/0xb0\n  ...\n  Call Trace:\n   ? debug_print_object+0x7d/0xb0\n   ? __pfx_doe_statemachine_work+0x10/0x10\n   debug_object_free.part.0+0x11b/0x150\n   doe_statemachine_work+0x45e/0x510\n   process_one_work+0x1d4/0x3c0\n\nThis occurs because destroy_work_on_stack() was called after signaling\nthe completion in the calling thread.  This creates a race between\ndestroy_work_on_stack() and the task-\u003ework struct going out of scope in\npci_doe().\n\nSignal the work complete after destroying the work struct.  This is safe\nbecause signal_task_complete() is the final thing the work item does and\nthe workqueue code is careful not to access the work struct after.","modified":"2026-04-02T09:45:42.240529Z","published":"2025-12-30T12:11:25.688Z","related":["SUSE-SU-2026:0278-1","SUSE-SU-2026:0281-1","SUSE-SU-2026:0293-1","SUSE-SU-2026:0315-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/54xxx/CVE-2023-54235.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/19cf3ba16dcc2ef059dcf010072d4f96d76486e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4f9c0a3a6df143f2e1092823b7fa9e07d6ab57f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d96799ee3b78962c80e4b6653734f488f999ca09"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e3a3a097eaebaf234a482b4d2f9f18fe989208c1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/54xxx/CVE-2023-54235.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-54235"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2a0e0f4773fe8032fb17e56f897bee32ce3cdc2b"},{"fixed":"d96799ee3b78962c80e4b6653734f488f999ca09"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"abf04be0e7071f2bcd39bf97ba407e7d4439785e"},{"fixed":"c4f9c0a3a6df143f2e1092823b7fa9e07d6ab57f"},{"fixed":"19cf3ba16dcc2ef059dcf010072d4f96d76486e0"},{"fixed":"e3a3a097eaebaf234a482b4d2f9f18fe989208c1"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"95628b830952943631d3d74f73f431f501c5d6f5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-54235.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.4.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.5.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-54235.json"}}],"schema_version":"1.7.5"}
