{"id":"CVE-2025-22027","summary":"media: streamzap: fix race between device disconnection and urb callback","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: streamzap: fix race between device disconnection and urb callback\n\nSyzkaller has reported a general protection fault at function\nir_raw_event_store_with_filter(). This crash is caused by a NULL pointer\ndereference of dev-\u003eraw pointer, even though it is checked for NULL in\nthe same function, which means there is a race condition. It occurs due\nto the incorrect order of actions in the streamzap_disconnect() function:\nrc_unregister_device() is called before usb_kill_urb(). The dev-\u003eraw\npointer is freed and set to NULL in rc_unregister_device(), and only\nafter that usb_kill_urb() waits for in-progress requests to finish.\n\nIf rc_unregister_device() is called while streamzap_callback() handler is\nnot finished, this can lead to accessing freed resources. Thus\nrc_unregister_device() should be called after usb_kill_urb().\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller.","modified":"2026-05-18T05:58:04.743485826Z","published":"2025-04-16T14:11:48.210Z","related":["SUSE-SU-2025:01614-1","SUSE-SU-2025:01707-1","SUSE-SU-2025:01919-1","SUSE-SU-2025:01951-1","SUSE-SU-2025:01964-1","SUSE-SU-2025:01967-1","SUSE-SU-2025:01972-1","SUSE-SU-2025:01983-1","SUSE-SU-2025:20343-1","SUSE-SU-2025:20344-1","SUSE-SU-2025:20354-1","SUSE-SU-2025:20355-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22027.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/15483afb930fc2f883702dc96f80efbe4055235e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/30ef7cfee752ca318d5902cb67b60d9797ccd378"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4db62b60af2ccdea6ac5452fd20e29587ed85f57"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8760da4b9d44c36b93b6e4cf401ec7fe520015bd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/adf0ddb914c9e5b3e50da4c97959e82de2df75c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e11652a6514ec805440c1bb3739e6c6236fffcc7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1d518c0bad01abe83c2df880274cb6a39f4a457"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f656cfbc7a293a039d6a0c7100e1c846845148c1"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22027.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22027"},{"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":"8e9e60640067858e8036d4d43bbf725c60613359"},{"fixed":"e11652a6514ec805440c1bb3739e6c6236fffcc7"},{"fixed":"f1d518c0bad01abe83c2df880274cb6a39f4a457"},{"fixed":"30ef7cfee752ca318d5902cb67b60d9797ccd378"},{"fixed":"15483afb930fc2f883702dc96f80efbe4055235e"},{"fixed":"adf0ddb914c9e5b3e50da4c97959e82de2df75c3"},{"fixed":"4db62b60af2ccdea6ac5452fd20e29587ed85f57"},{"fixed":"8760da4b9d44c36b93b6e4cf401ec7fe520015bd"},{"fixed":"f656cfbc7a293a039d6a0c7100e1c846845148c1"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-22027.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.36"},{"fixed":"5.10.237"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.181"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.134"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.87"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.23"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.13.11"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.14.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-22027.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
