Descriptions

Race condition in the audit_log_single_execve_arg function in kernel/auditsc.c in the Linux kernel through 4.7 allows local users to bypass intended character-set restrictions or disrupt system-call auditing by changing a certain string, aka a "double fetch" vulnerability.

Condición de carrera en la función audit_log_single_execve_arg en kernel/auditsc.c en el kernel de Linux hasta la versión 4.7 permite a usuarios locales eludir restricciones de set de caracteres intencionados o interrumpir la auditoria del sistema de llamada cambiando una cierta cadena, también conocido como una vulnerabilidad de "doble recuperación".

When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.
