Write-what-where Condition Affecting torvalds/linux package, versions [6.17,6.18.53)[6.19,7.2.9)
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 6.18.53, 7.2.9 or higher.
Overview
Affected versions of this package are vulnerable to Write-what-where Condition in the drm_pagemap_migrate_unmap_pages process. An attacker can gain unauthorized access to sensitive kernel or cross-process memory contents and perform arbitrary physical memory writes by exploiting improper DMA unmapping during memory migration errors. This can be achieved by creating a fault-mode virtual memory, migrating it to VRAM, and inducing errors that cause leaked IOMMU mappings to persist, allowing subsequent DMA operations to target recycled physical pages.
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
