A flaw was found in SSSD. A local attacker can exploit this vulnerability by sending a specially crafted request to the autofs responder UNIX socket. Due to improper buffer offset calculation during request parsing, the service performs an out-of-bounds memory read. This flaw can cause the autofs responder process to crash, resulting in a denial of service (DoS).

AI_ONLY_REPORT
package: sssd-2.12.0-1.el10
Summary: OOB Read in `autofs_read_getautomntent_input` via unchecked
effective offset (`SSS_AUTOFS_GETAUTOMNTENT`): a crafted local autofs
request can trigger a small out-of-bounds read in the responder parser and
may crash the autofs responder.
Requirements to exploit: A local attacker must be able to connect to the
autofs UNIX socket and send a crafted `SSS_AUTOFS_GETAUTOMNTENT` request.
The autofs responder must be enabled

The autofs responder must be enabled. The reviewed code suggests common
deployments expose this socket broadly, but actual reachability still
depends on the deployed socket and directory permissions.
