- Summary
- smb: client: fix dir separator in SMB1 UNIX mounts
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix dir separator in SMB1 UNIX mounts
When calling cifsmountgettcon() with SMB1 UNIX mounts, @cifssb->mntcifsflags needs to be read or updated only after calling resetcifsunixcaps(), otherwise it might end up with missing CIFSMOUNTPOSIXACL and CIFSMOUNTPOSIXPATHS bits.
This fixes the wrong dir separator used in paths caused by the missing CIFSMOUNTPOSIXPATHS bit in cifssbinfo::mntcifs_flags.
