Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.0.8
Description
The issue is related to a use-after-free in the
run unpack() function in the fs/ntfs3/run.c component of the Linux kernel. This occurs due to a difference between NTFS sector size and media sector size, potentially allowing an attacker to impact the confidentiality, integrity, and availability of protected information.Recommendations
For Linux kernel versions prior to 6.0.8, update to a version that includes the fix for this issue to prevent exploitation.
As a temporary workaround, consider restricting access to the
fs/ntfs3/run.c component until a patch is available.Exploit
