CVE-2024-42094

A flaw was found in the Linux kernel's net/iucv component. This vulnerability arises when a specific kernel configuration (CONFIG_CPUMASK_OFFSTACK=y) is enabled, allowing for explicit allocation of cpumask variables directly on the system's memory stack. An attacker could exploit this to trigger a stack overflow, potentially leading to a Denial of Service (DoS) condition, which would make the system unavailable.

This issue is considered to be a moderate impact flaw, as the exploitation in this will not cause an Intigrity (I:L) threat with the available usecase and may only cause a DOS.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
