If an\ninterrupt fires after usbhs_pipe_remove() but before the driver is fully\nunbound, the ISR may access freed memory, causing a use-after-free.\n\nFix this by calling devm_free_irq() before freeing resources. This ensures\nthe interrupt handler is both disabled and synchronized (waits for any\nrunning ISR to complete) before usbhs_pipe_remove() is called."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/renesas_usbhs/common.c"],"versions":[{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"c7012fc73dab4829404fedeeaa8531f12ac8545f","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"51afaf919bbaacdd9cc9e146033ae0a743a42dd7","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"1899edac312ef17a7234851686e8a703f56d0a84","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"9c6159d5b72d5fc265cce5da04f27d730b552e69","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"6287e0c01ccb818e7214f88d885ffb7c9e81b0e0","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"0b7d11fd6e742ecc0b1eca44b4f0b93140c74bae","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"6ffe44f022c95b1b29c691d2169c5abc046f7580","status":"affected","versionType":"git"},{"version":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647","lessThan":"3cbc242b88c607f55da3d0d0d336b49bf1e20412","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/usb/renesas_usbhs/common.c"],"versions":[{"version":"3.0","status":"affected"},{"version":"0","lessThan":"3.0","status":"unaffected","versionType":"semver"},{"version":"5.10.253","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.203","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.167","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.130","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.78","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.19","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.9","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","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":"3.0","versionEndExcluding":"5.10.253"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"5.15.203"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"6.1.167"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"6.6.130"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"6.12.78"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"6.18.19"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"6.19.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c7012fc73dab4829404fedeeaa8531f12ac8545f"},{"url":"https://git.kernel.org/stable/c/51afaf919bbaacdd9cc9e146033ae0a743a42dd7"},{"url":"https://git.kernel.org/stable/c/1899edac312ef17a7234851686e8a703f56d0a84"},{"url":"https://git.kernel.org/stable/c/9c6159d5b72d5fc265cce5da04f27d730b552e69"},{"url":"https://git.kernel.org/stable/c/6287e0c01ccb818e7214f88d885ffb7c9e81b0e0"},{"url":"https://git.kernel.org/stable/c/0b7d11fd6e742ecc0b1eca44b4f0b93140c74bae"},{"url":"https://git.kernel.org/stable/c/6ffe44f022c95b1b29c691d2169c5abc046f7580"},{"url":"https://git.kernel.org/stable/c/3cbc242b88c607f55da3d0d0d336b49bf1e20412"}],"title":"usb: renesas_usbhs: fix use-after-free in ISR during device removal","x_generator":{"engine":"bippy-1.2.0"}}}}
