NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-core package and not the kernel-zfcpdump-core package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

smb: client: mask server-provided mode to 07777 in modefromsid

When modefromsid is active, parse_dacl() applies the server-provided sub_auth[2] value from the NFS mode SID to cf_mode without masking to 07777. Apply the correct masking, same as in the read path.
