Local privilege escalation via SMB out-of-bounds write
Published May 26, 2022 · Updated Aug 3, 2024
Out-of-bounds write in Apple SMB on macOS Catalina, Big Sur, and Monterey allows local users to gain elevated privileges through an application. The SMB component writes beyond a buffer boundary because it does not adequately validate bounds before copying application-controlled data. Exploitation requires a local application and user interaction; successful exploitation grants that application elevated privileges.
