CVE-2026-68766
Description
A flaw was found in hashcat. This vulnerability allows an attacker to inject malicious command-line options when parsing restore files. By crafting a specially designed restore file, an attacker can append arbitrary content to files, potentially leading to arbitrary code execution on the system.
Statement
Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
Mitigation
To mitigate this issue, run hashcat in an isolated environment, such as a container or a dedicated virtual machine, to restrict its access to the host filesystem. Additionally, only process restore files from trusted sources to prevent the injection of malicious command-line options.
