EPSS · scored 2026-10-23

A vulnerability has been identified in Altair Grid Engine (All versions < V2026.0.0). Affected products do not properly validate environment variables when loading shared libraries, allowing path hijacking through malicious library substitution. This could allow a local attacker to execute arbitrary code with superuser privileges by manipulating the environment variable and placing a malicious library in the controlled path.
