{"id":"CVE-2026-98762","summary":"USB: dwc2: shut down wakeup timer before freeing HCD state","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: dwc2: shut down wakeup timer before freeing HCD state\n\ndwc2_wakeup_detected() accesses the DWC2 host state and can rearm the\nwakeup timer.  dwc2_hcd_free() currently deletes the timer only after\nfreeing host-owned state, and timer_delete() does not synchronize a\ncallback or prevent it from being queued again.\n\nStop and shut down the timer in dwc2_hcd_release(), before the HCD\nresources are freed.  This covers both the HCD initialization error path\nand normal HCD removal.","modified":"2026-11-01T02:33:40.389546134Z","published":"2026-10-18T15:47:53.656Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98762.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0b2ea59d66d046d5601ffc3e61dd09d3597c704e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4333174ea52c863a50bb3e0a4726bf9f7cdf7524"},{"type":"WEB","url":"https://git.kernel.org/stable/c/441be312fce927443eae2821f502344d953c38bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79ba37dd38a321cb32a79332a3e3c68dd334dca9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82cc242da6d621752718929e6a2fa6f9554ebffe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3d76baa5b902f681100447e9d185819c5c1316d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fd772af9512cdecb83de34a461801533828e77fd"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98762.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98762"},{"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":"7359d482eb4d3967cc8be354405ae6be6eaf732c"},{"fixed":"f3d76baa5b902f681100447e9d185819c5c1316d"},{"fixed":"0b2ea59d66d046d5601ffc3e61dd09d3597c704e"},{"fixed":"82cc242da6d621752718929e6a2fa6f9554ebffe"},{"fixed":"441be312fce927443eae2821f502344d953c38bb"},{"fixed":"4333174ea52c863a50bb3e0a4726bf9f7cdf7524"},{"fixed":"79ba37dd38a321cb32a79332a3e3c68dd334dca9"},{"fixed":"fd772af9512cdecb83de34a461801533828e77fd"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98762.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.10.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98762.json"}}],"schema_version":"1.9.2"}
