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 Improper Restriction of Operations within the Bounds of a Memory Buffer in the is_branch_taken process. An attacker can gain arbitrary kernel read and write capabilities by exploiting mispredicted JMP32 pointer versus zero comparisons in BPF programs, allowing them to execute code or overwrite credentials within the kernel.
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
