Readers call bcm_vk_drv_access_ok() before accessing the\nmessage queues and their cached queue information.\n\natomic_set()/atomic_read() do not order those accesses. A reader can see\nmsgq_inited set while still seeing stale queue information. Use release\nwhen publishing the initialized queues and acquire when checking the gate.\n\nKeep the clear in bcm_vk_blk_drv_access() as atomic_set(). It closes the\ngate and does not publish queue state to readers.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1df3926ed8771edf286ff753428b243f334e6041","https://git.kernel.org/stable/c/4984277bc43f84d7506346a09b29af138246d54a","https://git.kernel.org/stable/c/61b101c6a150057b6d512421ed108aed16e822ea","https://git.kernel.org/stable/c/679cfada6868723ccf162ec3b78c7402ff2405bf","https://git.kernel.org/stable/c/a45d6dd3c11e921882a2e74c7c8710b975f2eaa7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93052","score":0.00205,"percentile":0.10439,"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).
