CVE-2024-42224

A vulnerability was found in the Linux kernel's mv88e6xxx driver in the mv88e6xxx_default_mdio_bus() function, where an improper check for an empty linked list could lead to dereferencing a potentially invalid pointer. This issue could lead to memory corruption or crashes.

Red Hat believes this flaw to be of Moderate severity because this flaw primarily impacts an Ethernet switch driver, which operates at the network interface level, handling network data packets. As such, successful exploitation of this vulnerability could result in memory leakage but it would likely not contain sensitive data. A crash could impact the integrity of the system, but would most likely impact the integrity of the data flow within the network.

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.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
