In remove callback, the rx mailbox channel is cleaned up when the\nrx_chan is NULL due to incorrect condition check. The mailbox channel is\nnot shutdown and it can receive messages even after the device removal.\nThis leads to use after free. Also the channel resources are not freed.\nFix this by checking the rx_chan correctly.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/75ed49f973d790ca3111fcabd516c0b5fd0170b4","https://git.kernel.org/stable/c/a83e77d1e52c01c50096e6e97c57d34e0590d628","https://git.kernel.org/stable/c/b0f748c563921a7918c78e6a599cefd54de7d688","https://git.kernel.org/stable/c/b5d2240c2c7bc8370e7ba54a2e1fe3919f55aee5","https://git.kernel.org/stable/c/fdee7c66c0d7b6869c36b9f9a915abf29ab5b550"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-80654","score":0.00209,"percentile":0.10929,"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).
