CyberRota Analysis

AI-Generated

A vulnerability exists in the handling of SUID binaries during the execve(2) system call, where the new virtual address space is established prior to the update of process credentials. This timing issue allows an unprivileged local user to exploit the race condition, potentially modifying the address space of the SUID binary and gaining unauthorized control over the system. Organizations running SUID binaries should prioritize addressing this vulnerability to mitigate the risk of local privilege escalation.

Original NVD Description

During execve(2) of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging permission check still saw the original credentials. An unprivileged local user can exploit this race to modify the address space of a SUID binary before its credentials are elevated, potentially gaining full control of the affected system.
