| 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 (affected versions not specified)
Description
The issue is related to a null pointer dereference in the
mas empty area rev() function within the lib/maple tree.c module of the Linux kernel. This occurs when mas start() is called followed by mas data end() if the maple state is MA START, but mas start() may return with the maple state node being NULL. A user could trigger events to cause a kernel oops by unmapping all vmas to produce an empty maple tree, then mapping a vma that would cause this scenario.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
