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 Out-of-Bounds in the __ioam6_fill_trace_data process when processing IPv6 packets with IOAM Pre-allocated Trace options and trace->type.bit6 is set. An attacker can cause an out-of-bounds access of the dev->_tx[] array by sending crafted packets with a queue mapping that exceeds the number of TX queues on the egress device, potentially leading to kernel panic or leakage of sensitive kernel memory.
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
