In\nmonitor mode with the fcsfail filter enabled, the hardware passes up\ncorrupted frames, and a corrupted frame can report a length larger\nthan the received buffer. The bounds check correctly discards such\nframes, but its WARN_ON_ONCE wrapper means any over-the-air garbage\nframe taints the kernel, and panics it on the first such frame when\npanic_on_warn is set.\n\nDrop the WARN and discard the frame silently, matching what\ncommit c2d4c8723dbf (\"mt76x2: remove some harmless WARN_ONs in tx\nstatus and rx path\") did for the neighboring rx and tx status paths.\n\nObserved immediately on rx with an MT7612U in fcsfail monitor mode\non a busy channel.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/17d6b89e09eac2d90272fceeba3644e92212e02f","https://git.kernel.org/stable/c/2d31e332c13b1db7745a7bd9cf74bc105524bcac","https://git.kernel.org/stable/c/61b1f6d92249bc34580ff19de7c69c805f82adca","https://git.kernel.org/stable/c/6def491fe9c4e83aa8cba62d74e9d4ab751ee967","https://git.kernel.org/stable/c/81497634d9f872fd3e8b03aada55574afff6f174"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90382","score":0.00216,"percentile":0.11969,"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).
