Description Carlos López 2023-06-01 08:04:05 UTC 
CVE-2022-48502

An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem does
not properly check for correctness during disk reads, leading to an
out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c.

Comment 2 Carlos López 2023-06-01 08:33:37 UTC 
We only have CONFIG_NTFS3_FS enabled in stable and master (so Leap and Tumbleweed), and they both already got the fix:

Please confirm and I will close the bug.

Yes, we don't support NTFS in kernel filesystem for enterprise products.  So this can be closed. Thanks for following up.
