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 7.1.6 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the criu_checkpoint_queues_device process. An attacker can access sensitive kernel or GPU memory contents by supplying a crafted cp_hqd_cntl_stack_size value that causes an over-read, resulting in disclosure of adjacent memory to userspace. This is only exploitable if the attacker has access to /dev/kfd and possesses either the CAP_CHECKPOINT_RESTORE or CAP_SYS_ADMIN capability.
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
