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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/0093f9fc102ba8b98561fdd2f8559553ef56be59","https://git.kernel.org/stable/c/5f1a76ecfe90544a28d657306c9b3caa66ba0e63","https://git.kernel.org/stable/c/ec631aff93261c6d031f953549802322032f2aba"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-80950","score":0.00173,"percentile":0.06716,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
