the Linux kernel, the following vulnerability has been resolved:\n\nstaging: most: video: avoid double free on video register failure\n\ncomp_register_videodev() allocates a video_device with\nvideo_device_alloc() and releases it if video_register_device() fails.\n\nThis can double free the video_device when __video_register_device()\nreaches device_register() and that call fails:\n\n  video_register_device()\n    -> __video_register_device()\n       -> device_register() fails\n          -> put_device(&vdev->dev)\n             -> v4l2_device_release()\n                -> vdev->release(vdev)\n                   -> video_device_release(vdev)\n\n  comp_register_videodev()\n    -> video_device_release(mdev->vdev)\n\nUse video_device_release_empty() while registering the device so that\nregistration failure paths do not free mdev->vdev through vdev->release().\ncomp_register_videodev() then releases mdev->vdev exactly once on failure.\nRestore video_device_release() after successful registration so the\nregistered device keeps its normal lifetime handling.\n\nThis issue was found by a static analysis tool I am developing."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/staging/most/video/video.c"],"versions":[{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"009d58b73500d0b49f6ae3833f8afcb0ebd9ddbb","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"430ad4ea06a0767fb44a08e2212ceb3a996607ee","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"46ea51f5b2ee1a3b40c05b7c750cbc5cabe94062","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"4928096212b78262dbbeab3b3abf2352278ce22d","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"80ed79787da3311f76b4d71d0ce7ab992a9e134d","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"43078449ad6236d839e4d707954d2e36b10a6706","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"7fc162453cfb7b8e93edb16287a84ba0130cac38","status":"affected","versionType":"git"},{"version":"eab231c0398a91fbd294672bfe9e0ff45b368246","lessThan":"7cb1c5b32a2bfde961fff8d5204526b609bcb30a","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/staging/most/video/video.c"],"versions":[{"version":"4.9","status":"affected"},{"version":"0","lessThan":"4.9","status":"unaffected","versionType":"semver"},{"version":"5.10.261","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.212","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.178","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.145","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.97","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"4.9","versionEndExcluding":"5.10.261"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.15.212"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.1.178"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.6.145"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.12.97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/009d58b73500d0b49f6ae3833f8afcb0ebd9ddbb"},{"url":"https://git.kernel.org/stable/c/430ad4ea06a0767fb44a08e2212ceb3a996607ee"},{"url":"https://git.kernel.org/stable/c/46ea51f5b2ee1a3b40c05b7c750cbc5cabe94062"},{"url":"https://git.kernel.org/stable/c/4928096212b78262dbbeab3b3abf2352278ce22d"},{"url":"https://git.kernel.org/stable/c/80ed79787da3311f76b4d71d0ce7ab992a9e134d"},{"url":"https://git.kernel.org/stable/c/43078449ad6236d839e4d707954d2e36b10a6706"},{"url":"https://git.kernel.org/stable/c/7fc162453cfb7b8e93edb16287a84ba0130cac38"},{"url":"https://git.kernel.org/stable/c/7cb1c5b32a2bfde961fff8d5204526b609bcb30a"}],"title":"staging:
