A missing bounds check in the MediaTek WLAN STA driver can cause a system crash, leading to local denial of service. The vulnerability requires User execution privileges but does not require user interaction for exploitation. The issue has been assigned CWE-787 (Out-of-bounds Write) and is addressed by Patch ID WCNCR00480851.
A missing bounds check in the geniezone component creates an out-of-bounds write condition. The vulnerability requires an attacker to already hold System privilege, limiting exposure to post-compromise scenarios. No user interaction is needed for exploitation. The issue has been addressed via patch ALPS10873936 (Issue ID: MSV-6784).
A race condition in the geniezone component creates a possible out-of-bounds write.
