Summary
CVE-2026-64379 affecting package kernel for versions less than 6.6.145.2-1
Details

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.
