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-2026-98012 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.10.271, 5.15.222, 6.1.189, 6.6.158, 6.12.111, 5.5, 6.18.53, 7.2.7 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the sfq_change process. An attacker can cause excessive CPU consumption and a soft lockup by setting a crafted quantum value and size table, resulting in the deficit-refill loop spinning a large number of times under the qdisc lock. This is only exploitable if the kernel is configured with CONFIG_NET_SCH_SFQ=y and the attacker has CAP_NET_ADMIN privileges within the relevant namespace.
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
