That drops the last reference, so the device's\nrelease callback i3c_device_release() runs and frees the i3c_device.\n\nTwo problems follow from that:\n\ni3c_device_release() does WARN_ON(i3cdev->desc), so it warns because\ndesc->dev->desc still points back at the descriptor.  Clear it before\ncalling put_device().\n\nAfter put_device() frees the i3c_device, desc->dev is left pointing at\nfreed memory, so clear desc->dev as well.  That prevents, for example,\ni3c_master_unregister_i3c_devs() seeing desc->dev as non-NULL and\ndereferencing it."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/i3c/master.c"],"versions":[{"version":"1832ed55df45f4145335ad992fb83813cdc58b5d","lessThan":"5bf498623f8397d45f85f14cd631c5e5a565c2fb","status":"affected","versionType":"git"},{"version":"d48fe8d98171e0fffdeaa8b37ce0a6444bff819b","lessThan":"20a2b6df91fd782ef2ff551febef594d0b46a9a7","status":"affected","versionType":"git"},{"version":"174ae0a3b89e7804e4ea3d31bd83d6e43f39568c","lessThan":"a14dbdf471001dd0601b0c491184990c178a199c","status":"affected","versionType":"git"},{"version":"e49a51a96b531f1b4bcd8d358e645b6c74ef67e6","lessThan":"d22ad96f1a0c89e0ba66a2facc7430f0923919e3","status":"affected","versionType":"git"},{"version":"cab63f64887616e3c4e31cfd8103320be6ebc8d3","lessThan":"7f8e2c4f3704d9774bb26b49b1ad6a60ae57d4a0","status":"affected","versionType":"git"},{"version":"cab63f64887616e3c4e31cfd8103320be6ebc8d3","lessThan":"7ef12e1dd06e442eebf370f6e53c41bd056d0f22","status":"affected","versionType":"git"},{"version":"cab63f64887616e3c4e31cfd8103320be6ebc8d3","lessThan":"6ecf17bf5fe8da51a6e3fc9e03a76898fcc5c6cf","status":"affected","versionType":"git"},{"version":"cab63f64887616e3c4e31cfd8103320be6ebc8d3","lessThan":"74be657d98a8d684c0475f3cbd450ef2a30ffc73","status":"affected","versionType":"git"},{"version":"204beeb509d37669de34560e83bb8abffe7ee63a","status":"affected","versionType":"git"},{"version":"b24cf43d9babf1265a2bb0ae8d198267cef43b83","status":"affected","versionType":"git"},{"version":"5.10.201","lessThan":"5.10.270","status":"affected","versionType":"semver"},{"version":"5.15.139","lessThan":"5.15.221","status":"affected","versionType":"semver"},{"version":"6.1.63","lessThan":"6.1.188","status":"affected","versionType":"semver"},{"version":"6.6.2","lessThan":"6.6.157","status":"affected","versionType":"semver"},{"version":"5.4.261","lessThan":"5.5","status":"affected","versionType":"semver"},{"version":"6.5.12","lessThan":"6.6","status":"affected","versionType":"semver"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/i3c/master.c"],"versions":[{"version":"6.7","status":"affected"},{"version":"0","lessThan":"6.7","status":"unaffected","versionType":"semver"},{"version":"5.10.270","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.221","lessThanOrEqual":"5.15.*","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":"5.10.201","versionEndExcluding":"5.10.270"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15.139","versionEndExcluding":"5.15.221"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.63","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6.2","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"7.3-rc1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4.261"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/5bf498623f8397d45f85f14cd631c5e5a565c2fb"},{"url":"https://git.kernel.org/stable/c/20a2b6df91fd782ef2ff551febef594d0b46a9a7"},{"url":"https://git.kernel.org/stable/c/a14dbdf471001dd0601b0c491184990c178a199c"},{"url":"https://git.kernel.org/stable/c/d22ad96f1a0c89e0ba66a2facc7430f0923919e3"},{"url":"https://git.kernel.org/stable/c/7f8e
