Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.10.9 and classified as critical. Affected by this vulnerability is the function overflow_allocation_test. The manipulation of the argument device_name with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: kunit/overflow: Fix UB in overflow_allocation_test The 'device_name' array doesn't exist out of the 'overflow_allocation_test' function scope. However, it is being used as a driver name when calling 'kunit_driver_create' from 'kunit_device_register'. It produces the kernel panic with KASAN enabled. Since this variable is used in one place only, remove it and pass the device name into kunit_device_register directly as an ascii string.

It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2024-46823 since 09/11/2024. Technical details of the vulnerability are known, but there is no available exploit.
