CVE-2026-50292
HighCVSS 7.4Exploitation Probability (EPSS)
Low risk40th percentile - higher than 40% of all known CVEs
Summary
In libinput before 1.30.4 and 1.31.x before 1.31.3, libinput-device-group unescaped phys output can inject udev properties leading to arbitrary root code execution.
Risk Assessment
An attacker can gain full root control over the system by injecting udev properties, potentially leading to complete system compromise.
Recommendation
Upgrade libinput to version 1.30.4 or 1.31.3, which include a fix for escaping phys output.
Other vulnerabilities in libinput
See all- CVE-2026-35094Low
A dangling pointer flaw was found in libinput. It occurs when a garbage collection cleanup function is called, leaving a pointer that can then be printed to system logs. This could potentially expose sensitive data if the memory location is re-used. Exploitation requires Lua plugins to be enabled in libinput and loaded by the compositor, and the ability to deploy a plugin file in specific system directories.
- CVE-2026-35093High
A flaw was found in libinput that allows a local attacker to bypass security restrictions by placing a specially crafted Lua bytecode file in certain system or user configuration directories. The attacker can run unauthorized code with the same permissions as the program using libinput, such as a graphical compositor. This could lead to monitoring keyboard input and sending that information to an external location.
