Name of the Vulnerable Software and Affected Versions Linux kernel version 4.15.0

Description The issue is related to the ntfs attr find function in the ntfs.ko filesystem driver, which allows attackers to trigger a stack-based out-of-bounds write. This can cause a denial of service, resulting in a kernel oops or panic, and may have other unspecified impacts. The attack is possible via a crafted ntfs filesystem.

Recommendations For Linux kernel version 4.15.0, consider upgrading to a newer version that includes a fix for this issue. As a temporary workaround, restrict access to ntfs filesystems to minimize the risk of exploitation.
