{"id":"CVE-2026-43426","summary":"usb: renesas_usbhs: fix use-after-free in ISR during device removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: renesas_usbhs: fix use-after-free in ISR during device removal\n\nIn usbhs_remove(), the driver frees resources (including the pipe array)\nwhile the interrupt handler (usbhs_interrupt) is still registered. 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.","modified":"2026-07-22T18:22:29.202226529Z","published":"2026-05-08T14:21:59.668Z","related":["SUSE-SU-2026:3130-1","SUSE-SU-2026:3166-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43426.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0b7d11fd6e742ecc0b1eca44b4f0b93140c74bae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1899edac312ef17a7234851686e8a703f56d0a84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3cbc242b88c607f55da3d0d0d336b49bf1e20412"},{"type":"WEB","url":"https://git.kernel.org/stable/c/51afaf919bbaacdd9cc9e146033ae0a743a42dd7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6287e0c01ccb818e7214f88d885ffb7c9e81b0e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ffe44f022c95b1b29c691d2169c5abc046f7580"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c6159d5b72d5fc265cce5da04f27d730b552e69"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c7012fc73dab4829404fedeeaa8531f12ac8545f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43426.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43426"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f1407d5c66240b33d11a7f1a41d55ccf6a9d7647"},{"fixed":"c7012fc73dab4829404fedeeaa8531f12ac8545f"},{"fixed":"51afaf919bbaacdd9cc9e146033ae0a743a42dd7"},{"fixed":"1899edac312ef17a7234851686e8a703f56d0a84"},{"fixed":"9c6159d5b72d5fc265cce5da04f27d730b552e69"},{"fixed":"6287e0c01ccb818e7214f88d885ffb7c9e81b0e0"},{"fixed":"0b7d11fd6e742ecc0b1eca44b4f0b93140c74bae"},{"fixed":"6ffe44f022c95b1b29c691d2169c5abc046f7580"},{"fixed":"3cbc242b88c607f55da3d0d0d336b49bf1e20412"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43426.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.78"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.19"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43426.json"}}],"schema_version":"1.7.5"}
