CVE-2024-42113

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.43

Description The vulnerability is related to the use of an uninitialized resource in the Linux kernel's net component. When using MSI/INTx interrupts, the wx->num q vectors variable is uninitialized, leading to a kernel panic in the wx alloc q vectors() function. This issue can be exploited to cause a denial of service.

Recommendations To resolve the issue, update the Linux kernel to version 6.6.43 or later. As a temporary workaround, consider disabling the use of MSI/INTx interrupts until a patch is available. Restrict access to the vulnerable net component to minimize the risk of exploitation. Avoid using the wx alloc q vectors() function until the issue is resolved.
