| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.2
Description
The issue is related to the ntfs3 subsystem in the Linux kernel, which does not properly check for correctness during disk reads. This leads to an out-of-bounds read in the
ntfs set ea function in fs/ntfs3/xattr.c. The vulnerability can be exploited to gain access to protected information or cause a denial of service.Recommendations
For Linux kernel versions prior to 6.2, update to version 6.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the
ntfs set ea function in fs/ntfs3/xattr.c to minimize the risk of exploitation.Exploit
