Microsoft Windows Kernel-Mode Driver Untrusted Pointer Dereference

Published Updated By the CyberSecBulletin desk

CVE-2024-35250 is a high-severity untrusted pointer dereference vulnerability in Windows 10 Version 1507 from Microsoft, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 10.0.10240.20680 as the first without the flaw, so updating Windows 10 Version 1507 to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on December 16, 2024, which means attacks have been observed in the wild.
