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.

CVE-2026-43309 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 4.15, 4.20, 5.5, 5.11, 5.16, 5.20, 6.12.114, 6.18.16, 6.19.6 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure through the md_stop process. An attacker can cause the system to hang indefinitely by triggering the removal of a top-level RAID device while its underlying metadata and data devices are suspended. This is only exploitable if a dm-raid managed device tree is suspended from top to bottom and the top-level RAID device is then removed.
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
