These\nreferences are normally released by mhi_ep_destroy_device() before the\ndevice itself is removed.\n\nIf dev_set_name() or device_add() fails, the error path currently drops\nonly one reference. The remaining channel references keep the device\nfrom being released and leave the channels associated with a device that\nwas never registered.\n\nRoute both failures through a common unwind path that drops the DL\nchannel reference, the UL channel reference, and the initial reference\nfrom device_initialize()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/bus/mhi/ep/main.c"],"versions":[{"version":"297c77a0f27312b9a04696018c4cbd47926ca92b","lessThan":"8acc3813ab5015af73eeb74c9032443162f122d1","status":"affected","versionType":"git"},{"version":"297c77a0f27312b9a04696018c4cbd47926ca92b","lessThan":"51ddb831a36102fd0ea25f354935e49abce9f0a1","status":"affected","versionType":"git"},{"version":"297c77a0f27312b9a04696018c4cbd47926ca92b","lessThan":"4fae8fd4adc7f4765463ddeb1a5fad23936432f6","status":"affected","versionType":"git"},{"version":"297c77a0f27312b9a04696018c4cbd47926ca92b","lessThan":"5587e7871ce994bb079f97fe7e430d99627e5292","status":"affected","versionType":"git"},{"version":"297c77a0f27312b9a04696018c4cbd47926ca92b","lessThan":"8f3f64faee335eb678fd7dca7b95dfe3d0b271fd","status":"affected","versionType":"git"},{"version":"297c77a0f27312b9a04696018c4cbd47926ca92b","lessThan":"6f12862600bb70e599a614d706a095ea5f8f9858","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/bus/mhi/ep/main.c"],"versions":[{"version":"5.19","status":"affected"},{"version":"0","lessThan":"5.19","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","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":"5.19","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8acc3813ab5015af73eeb74c9032443162f122d1"},{"url":"https://git.kernel.org/stable/c/51ddb831a36102fd0ea25f354935e49abce9f0a1"},{"url":"https://git.kernel.org/stable/c/4fae8fd4adc7f4765463ddeb1a5fad23936432f6"},{"url":"https://git.kernel.org/stable/c/5587e7871ce994bb079f97fe7e430d99627e5292"},{"url":"https://git.kernel.org/stable/c/8f3f64faee335eb678fd7dca7b95dfe3d0b271fd"},{"url":"https://git.kernel.org/stable/c/6f12862600bb70e599a614d706a095ea5f8f9858"}],"title":"bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation","x_generator":{"engine":"bippy-1.2.0"}}}}
