| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.74
Description
The issue arises from the
migrate to node() function assuming there is at least one VMA in a MM, which is not always true. This can lead to find vma() returning NULL, and subsequently, a null pointer dereference. The problem is resolved by properly handling the case where find vma() returns NULL. This fix addresses a report of a general protection fault, likely due to a non-canonical address.Recommendations
To resolve the issue, update the Linux kernel to version 6.6.74 or later. As a temporary workaround, consider disabling the
migrate to node() function until a patch is available. However, this is not a recommended long-term solution, as it may impact system performance and functionality.Note: The provided information does not specify the exact versions that are vulnerable, only that version 6.6.74 fixes the issue. Therefore, it is assumed that all versions prior to 6.6.74 are potentially vulnerable.
