CVE-2026-9111 [HIGH] libwebrtc vendor-pin lag: 2 confirmed + 6 suspected unpatched Chrome 148 WebRTC CVEs (CVE-2026-9111 Critical UAF, CVE-2026-9120 High UAF)
libwebrtc vendor-pin lag: 2 confirmed + 6 suspected unpatched Chrome 148 WebRTC CVEs (CVE-2026-9111 Critical UAF, CVE-2026-9120 High UAF)
Steps to reproduce:
## Vendor-Pin Lag Analysis
Firefox's vendored libwebrtc (third_party/libwebrtc/) is pinned to WebRTC M148 branch commit 9600e77d854090669817d22aa2fc941ee92aaacd, last vendored on 2026-04-22.
Between that date and 2026-05-24, Chrome 148 stable channel has published 9 WebRTC CVEs across 3 patch releases. Of these, 1 (CVE-2026-9119, Bug chromium:502661101) is likely already fixed in Firefox — its fix commit 9c2497e landed on M148 Apr 20, before Firefox's pin.
Of the remaining 8, 2 have confirmed post-pin fix CLs (CVE-2026-9111 → 6316b66d, CVE-2026-9120 → 9a7f650b) and 6 are suspected unpatched with fix CLs not yet mapped.

## Windows Netlogon: critical RCE
Anyone responsible for securing a domain controller should prioritize remediation of CVE-2026-41089 , which is a critical stack-based buffer overflow in Windows Netlogon with a CVSS v3 base score of 9.8. Exploitation leads to execution in the context of the Netlogon service, so that’s SYSTEM privileges on the domain controller. For most pentesters, that’s the point at which the customer report more or less writes itself. No privileges
