CVE-2024-27070
CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.7.0
Description:
The issue is related to a use-after-free problem in the
f2fs filemap fault() function. This occurs because vmf->vma may not be alive after filemap fault(), potentially causing a use-after-free issue when accessing vmf->vma->vm flags in trace f2fs filemap fault(). To resolve this, it is necessary to keep vm flags in a separate temporary variable for tracepoint use.Recommendations:
To resolve the issue, update the Linux kernel to a version that includes the fix for the use-after-free issue in
f2fs filemap fault(). As a temporary workaround, consider disabling the f2fs filemap fault() function until a patch is available. However, this may have significant performance implications and should be carefully considered before implementation.At the moment, there is no information about a newer version that contains a fix for this vulnerability.
