CVE-2023-39193

A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.

From the Ubuntu Security Team

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate SCTP data, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information.
