1.2
CVSS v3.1
Official Description
A race condition in the way env_start and env_end pointers are initialized in the execve system call and used in fs/proc/base.c on Linux 2.4 allows local users to cause a denial of service (crash).
Technical Analysis
CVE-2003-0462 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2003-0462. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
