CVE-2026-29923

The pstrip64.sys driver in EnTech Taiwan PowerStrip (versions ≤ 3.90.736) contains a local privilege escalation vulnerability. An unprivileged user-mode process can exploit the 0x80002008 IOCTL request to map arbitrary physical memory into its virtual address space by abusing ZwMapViewOfSection v...

CVE-2026-23401

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...

pstrip64.sys Privilege Escalation

The pstrip64.sys kernel driver exposes an IOCTL that allows low-privileged users to map arbitrary ranges of physical memory into their own virtual address space. This primitive allows full read/write access to the system's physical RAM, enabling attackers to modify critical kernel structures and...

The vulnerabilities of the `perf mmap()` and `perf mmap close()` functions in the Linux operating system’s kernel allow a hacker to trigger a service failure.

The vulnerability of the perf mmap and perf mmap close functions in Linux kernel relates to a violation of the count of references to pages stored in memory. Exploiting this vulnerability can allow an attacker to trigger a service failure...
