An Improper Access Control vulnerability in the Stylus Tools component of Google ChromeOS version 16238.64.0 on the garaged stylus devices allows a physical attacker to bypass the lock screen and access user files by removing the stylus while the device is closed and using the screen capture feature.
Critical permissions bypass vulnerability in Google Chrome OS 16181.27.0 that allows local attackers to disable extensions and gain unauthorized access to Developer Mode on managed Chrome devices. The vulnerability is exploited using the ExtHang3r and ExtPrint3r tools to load arbitrary extensions, affecting enterprise-managed deployments with a CVSS score of 9.8 (critical severity). Active exploitation status and proof-of-concept availability should be verified through CISA KEV and security advisories.
Local privilege escalation vulnerability in Google ChromeOS MiniOS that allows unauthenticated attackers to achieve root code execution by exploiting an accessible debug shell (VT3 console) through specific key combinations during developer mode entry, circumventing device policy restrictions and Firmware Write Protect mechanisms. This vulnerability affects ChromeOS version 16063.45.2 and potentially other versions on enrolled devices, with a CVSS score of 7.4 indicating high severity. The attack requires local access and specific technical knowledge of key sequences, but no user interaction is needed once device access is obtained.
Out-of-Bounds Read in Virglrenderer in ChromeOS 16093.57.0 allows a malicious guest VM to achieve arbitrary address access within the crosvm sandboxed process, potentially leading to VM escape via. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
A race condition Use-After-Free vulnerability exists in the virtio_transport_space_update function within the Kernel 5.4 on ChromeOS. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. Public exploit code available and no vendor patch available.
Out-of-Bounds Read in netfilter/ipset in Linux Kernel ChromeOS [6.1, 5.15, 5.10, 5.4, 4.19] allows a local attacker with low privileges to trigger an out-of-bounds read, potentially leading to. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
ComponentInstaller Modification in ComponentInstaller in Google ChromeOS 15823.23.0 on Chromebooks allows enrolled users with local access to unenroll devices and intercept device management requests. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Access Control Vulnerability in Gerrit chromiumos project configuration in Google ChromeOS 16063.87.0 allows an attacker with a registered Gerrit account to inject malicious code into ChromeOS. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
DNS Leak in Native System VPN in Google ChromeOS Dev Channel on ChromeOS 16002.23.0 allows network observers to expose plaintext DNS queries via failure to properly tunnel DNS traffic during VPN. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Privilege escalation in Installer and Recovery image handling in Google ChromeOS version 15786.48.2 on device allows an attacker with physical access to gain root code execution and potentially. Rated medium severity (CVSS 6.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
