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.","published":"2026-05-08T15:16:55.000Z","lastModified":"2026-06-17T10:49:35.000Z","status":"Analyzed","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":["linux/linux kernel"],"epss":{"score":0.00126,"percentile":0.02242,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%).
