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 Use After Free due to improper handling of object aggregation in the objagg library when processing hints. An attacker can cause kernel memory corruption, information disclosure, and system crash by crafting specific filter masks and insertion orders that trigger unsupported nesting during the aggregation process. This is only exploitable if the attacker has CAP_NET_ADMIN privileges in a network namespace and can install offloaded tc flower filters on an mlxsw Spectrum-2+ port, allowing the driver's periodic ACL region rehash work to consume attacker-controlled hints.
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
