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.

Upgrade torvalds/linux to version 5.10.271, 5.15.222, 6.1.189, 6.6.158, 6.12.112, 6.18.54, 7.2.8 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Overflow in the iommu_tce_check_ioba function. An attacker can corrupt host kernel memory and access or modify data outside the intended bounds by issuing specially crafted hypercalls from a guest virtual machine, leading to potential host memory disclosure, modification, or denial of service. This is only exploitable if the attacker has kernel privileges within a guest VM and can issue H_STUFF_TCE or H_PUT_TCE_INDIRECT hypercalls.
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
