A vulnerability in the Linux kernel's SMB client implementation allowed the setuid/setgid bits on files to persist after writes when using certain CIFS mount options (cifsacl, modefromsid, or SMB3.1.1 POSIX extensions). Normally, these bits are cleared on write to prevent privilege escalation, but due to improper handling, the cleared mode was not propagated to the server, allowing the bits to survive and potentially enable privilege escalation.
