CVE-2026-79992: Red Hat Enterprise Linux 10

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution.
