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"}}}}
