Description
The vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in the compat_get_timex function, as defined in the kernel/compat.c source code file due to an uninitialized struct field in compat adjtimex system calls. A local attacker can send a compat adjtimex system call that submits malicious input and access sensitive kernel memory content, which could be used to conduct further attacks.
Remediation
