It\nprepares a struct renesas_i3c_xfer, enqueues it, and waits for completion.\nThe interrupt handler dequeues the transfer, updates/uses it, and signals\nthe waiting thread.\n\nIf the completion times out, the waiting thread dequeues the transfer and\nfree it. If an interrupt fires after that, the handler may access freed\nmemory, leading to crashes.\n\nCheck that the transfer is still valid before accessing it in the\ninterrupt handler. With it clear any status flags and disable all\nthe interrupts to avoid triggering the same interrupts again.","published":"2026-09-11T20:19:01.000Z","lastModified":"2026-10-19T09:17:26.000Z","status":"Received","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":[],"affected":[],"epss":{"score":0.00173,"percentile":0.06721,"date":"2026-10-26","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 (0.17%).
