CVE-2026-35094 (GCVE-0-2026-35094)

Vulnerability from nvd – Published: 2026-04-01 13:54 – Updated: 2026-04-01 15:50

Title
Libinput: libinput: information disclosure via dangling pointer in lua plugin handling
Summary
A flaw was found in libinput. An attacker capable of deploying a Lua plugin file in specific system directories can exploit a dangling pointer vulnerability. This 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, leading to information disclosure. For this exploit to work, Lua plugins must be enabled in libinput and loaded by the compositor.

CVE-2026-35093 (GCVE-0-2026-35093)

Vulnerability from nvd – Published: 2026-04-01 13:54 – Updated: 2026-04-03 13:56

Title
Libinput: libinput: unauthorized code execution and information disclosure through lua bytecode plugins
Summary
A flaw was found in libinput. A local attacker who can place a specially crafted Lua bytecode file in certain system or user configuration directories can bypass security restrictions. This allows the attacker to run unauthorized code with the same permissions as the program using libinput, such as a graphical compositor. This could lead to the attacker monitoring keyboard input and sending that information to an external location.

CVE-2026-35094 (GCVE-0-2026-35094)

Vulnerability from cvelistv5 – Published: 2026-04-01 13:54 – Updated: 2026-04-01 15:50

Title
Libinput: libinput: information disclosure via dangling pointer in lua plugin handling
Summary
A flaw was found in libinput. An attacker capable of deploying a Lua plugin file in specific system directories can exploit a dangling pointer vulnerability. This 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, leading to information disclosure. For this exploit to work, Lua plugins must be enabled in libinput and loaded by the compositor.

CVE-2026-35093 (GCVE-0-2026-35093)

Vulnerability from cvelistv5 – Published: 2026-04-01 13:54 – Updated: 2026-04-03 13:56

Title
Libinput: libinput: unauthorized code execution and information disclosure through lua bytecode plugins
Summary
A flaw was found in libinput. A local attacker who can place a specially crafted Lua bytecode file in certain system or user configuration directories can bypass security restrictions. This allows the attacker to run unauthorized code with the same permissions as the program using libinput, such as a graphical compositor. This could lead to the attacker monitoring keyboard input and sending that information to an external location.
