CVE-2026-22887
Kernel buffer bug in Intel PROSet/Wireless allows unauthenticated adjacent DoS
Is CVE-2026-22887 being exploited?
Not confirmed. CVE-2026-22887 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.
