1) Out-of-bounds read (CVE-ID: CVE-2023-39197)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the Netfilter Connection Tracking (conntrack) in the Linux kernel in the nf_conntrack_dccp_packet() function in net/netfilter/nf_conntrack_proto_dccp.c. A remote attacker can send specially crafted DCCP packets to the system, trigger an out-of-bounds read error and read contents of memory on the system.
