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.

Upgrade torvalds/linux to version 6.18.52, 7.2.6 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Type Conversion or Cast due to improper type enforcement in the bpf_cpumask_populate function. An attacker can overwrite kernel cpumask structures by supplying attacker-controlled data, potentially causing the kernel to execute scheduler operations on offline CPUs or report zero online CPUs, which may result in a kernel oops or system hang. This is only exploitable if the attacker is able to load and execute a BPF program with sufficient privileges.
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
