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.

CVE-2026-46319 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.10.258, 5.15.209, 6.1.175, 6.6.141, 6.12.91, 6.18.33, 7.0.10 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the tcf_ct_flow_table_get process. An attacker can achieve privilege escalation, arbitrary memory read, memory corruption, or denial of service by exploiting a race condition between the lookup and reference count increment of a flow table object, which can result in use-after-free of kernel memory. This is only exploitable if an attacker has CAP_NET_ADMIN privileges and can perform concurrent netlink operations on actions sharing the same zone.
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
