CVE-2026-57968 Published on July 14, 2026
Windows Subsystem for Linux (WSL2) Kernel Elevation of Privilege Vulnerability
Buffer over-read in Windows Subsystem for Linux allows an authorized attacker to elevate privileges locally.
Weakness Type
Buffer Over-read
The software reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer. This typically occurs when the pointer or its index is incremented to a position beyond the bounds of the buffer or when pointer arithmetic results in a position outside of the valid memory location to name a few. This may result in exposure of sensitive information or possibly a crash.
