Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Overview
Affected versions of this package are vulnerable to Buffer Overflow in the ip6_setup_cork process when handling UDP sockets with setsockopt IPV6_MTU_DISCOVER set to IPV6_PMTUDISC_DO or IPV6_PMTUDISC_PROBE and sending a large packet over a network device with an unusually large MTU. An attacker can cause an overflow of the UDP length field by sending a specially crafted large payload, potentially leading to memory corruption or system instability.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
