Researchers Find 34 Windows Drivers Vulnerable to Full Device Takeover

As many as 34 unique vulnerable Windows Driver Model WDM and Windows Driver Frameworks WDF drivers could be exploited by non-privileged threat actors to gain full control of the devices and execute arbitrary code on the underlying systems. "By exploiting the drivers, an attacker without privilege...

SUSE CVE-2017-2618

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty null write to this file can crash the system by causing the system to attempt to access unmapped kernel memory...

DEBIAN-CVE-2023-46813

An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory and th...
