An issue in the with_argv function of the relibc library allows attackers to trigger a denial of service by supplying specially crafted input. The vulnerability arises because the function does not properly validate the arguments, causing unexpected termination or resource exhaustion. The impact is a loss of availability for the affected application.

The flaw exists in the relibc component of the Redox operating system, specifically in commit 61f42d. Any version of Redox that includes this commit without the subsequent fix may be affected, regardless of vendor‑provided classification.

The EPSS score for this vulnerability is not available, and it is not listed in CISA’s KEV catalog, suggesting no publicly known exploits. The likely attack vector is through user input to applications that use relibc’s with_argv, and the vulnerability requires the attacker to provide crafted arguments. While the absence of an exploit probability score indicates low exploitation likelihood, the impact remains a critical availability failure if exploited.
