This is happening in the DRM framework for example.\n\nWe should thus call devres_release_all() in the device_del() function to\nmake sure that the device-managed actions are properly executed when the\ndevice is unregistered, even if it has neither a bus nor a driver.\n\nThis is effectively the same change than commit 2f8d16a996da (\"devres:\nrelease resources on device_del()\") that got reverted by commit\na525a3ddeaca (\"driver core: free devres in device_release\") over\nmemory leaks concerns.\n\nThis patch effectively combines the two commits mentioned above to\nrelease the resources both on device_del() and device_release() and get\nthe best of both worlds."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/base/core.c","drivers/base/test/platform-device-test.c","drivers/base/test/root-device-test.c"],"versions":[{"version":"a525a3ddeaca69f405d98442ab3c0746e53168dc","lessThan":"297992e5c63528e603666e36081836204fc36ec9","status":"affected","versionType":"git"},{"version":"a525a3ddeaca69f405d98442ab3c0746e53168dc","lessThan":"3bcc4c2a096e8342c8c719e595ce15de212694dd","status":"affected","versionType":"git"},{"version":"a525a3ddeaca69f405d98442ab3c0746e53168dc","lessThan":"c8c426fae26086a0ca8ab6cc6da2de79810ec038","status":"affected","versionType":"git"},{"version":"a525a3ddeaca69f405d98442ab3c0746e53168dc","lessThan":"699fb50d99039a50e7494de644f96c889279aca3","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/base/core.c","drivers/base/test/platform-device-test.c","drivers/base/test/root-device-test.c"],"versions":[{"version":"3.7","status":"affected"},{"version":"0","lessThan":"3.7","status":"unaffected","versionType":"semver"},{"version":"6.1.53","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.4.16","lessThanOrEqual":"6.4.*","status":"unaffected","versionType":"semver"},{"version":"6.5.3","lessThanOrEqual":"6.5.*","status":"unaffected","versionType":"semver"},{"version":"6.6","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":"3.7","versionEndExcluding":"6.1.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.4.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.5.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.6"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/297992e5c63528e603666e36081836204fc36ec9"},{"url":"https://git.kernel.org/stable/c/3bcc4c2a096e8342c8c719e595ce15de212694dd"},{"url":"https://git.kernel.org/stable/c/c8c426fae26086a0ca8ab6cc6da2de79810ec038"},{"url":"https://git.kernel.org/stable/c/699fb50d99039a50e7494de644f96c889279aca3"}],"title":"drivers: base: Free devm resources when unregistering a device","x_generator":{"engine":"bippy-1.2.0"}}}}
