This crash is caused by a NULL pointer\ndereference of dev->raw 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->raw\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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/media/rc/streamzap.c"],"versions":[{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"e11652a6514ec805440c1bb3739e6c6236fffcc7","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"f1d518c0bad01abe83c2df880274cb6a39f4a457","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"30ef7cfee752ca318d5902cb67b60d9797ccd378","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"15483afb930fc2f883702dc96f80efbe4055235e","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"adf0ddb914c9e5b3e50da4c97959e82de2df75c3","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"4db62b60af2ccdea6ac5452fd20e29587ed85f57","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"8760da4b9d44c36b93b6e4cf401ec7fe520015bd","status":"affected","versionType":"git"},{"version":"8e9e60640067858e8036d4d43bbf725c60613359","lessThan":"f656cfbc7a293a039d6a0c7100e1c846845148c1","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/media/rc/streamzap.c"],"versions":[{"version":"2.6.36","status":"affected"},{"version":"0","lessThan":"2.6.36","status":"unaffected","versionType":"semver"},{"version":"5.10.237","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.181","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.134","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.87","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.23","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13.11","lessThanOrEqual":"6.13.*","status":"unaffected","versionType":"semver"},{"version":"6.14.2","lessThanOrEqual":"6.14.*","status":"unaffected","versionType":"semver"},{"version":"6.15","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.10.237"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.15.181"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.1.134"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.6.87"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.12.23"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.13.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.14.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.15"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/e11652a6514ec805440c1bb3739e6c6236fffcc7"},{"url":"https://git.kernel.org/stable/c/f1d518c0bad01abe83c2df880274cb6a39f4a457"},{"url":"https://git.kernel.org/stable/c/30ef7cfee752ca318d5902cb67b60d9797ccd378"},{"url":"https://git.kernel.org/stable/c/15483afb930fc2f883702dc96f80efbe4055235e"},{"url":"https://git.kernel.org/stable/c/adf0ddb914c9e5b3e50da4c97959e82de2df75c3"},{"url":"https://git.kernel.org/stable/c/4db62b60af2ccdea6ac5452fd20e29587ed85f57"},{"url":"https://git.kernel.org/stable/c/8760da4b9d44c36b93b6e4cf401ec7fe520015bd"},{"url":"https://git.kernel.org/stable/c/f656cfbc7a293a039d6a0c7100e1c846845148c1"}],"title":"media:
