- [none]
- Details

In the Linux kernel, the following vulnerability has been resolved: mm/ksm: fix race with VMA iteration and mmstruct teardown exitmmap() will tear down the VMAs and maple tree with the mmaplock held in write mode. Ensure that the maple tree is still valid by checking ksmtestexit() after taking the mmaplock in read mode, but before the foreachvma() iterator dereferences a destroyed maple tree. Since the maple tree is destroyed, the flags telling lockdep to check an external lock has been cleared. Skip the foreachvma() iterator to avoid dereferencing a maple tree without the external lock flag, which would create a lockdep warning.
