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. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Buffer Overflow in the igc_fpe_init_smd_frame process. An attacker can cause kernel memory corruption, privilege escalation, arbitrary kernel memory disclosure, heap corruption, arbitrary code execution, or denial of service by sending specially crafted Ethernet SMD-V frames to a host with FPE/pMAC enabled, which triggers the reuse of stale buffer types in the TX completion path.
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
