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-2024-53224 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 6.1.191, 6.6.64, 6.11.11, 6.12.2 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the setup_qp function. An attacker can cause a kernel panic or potentially achieve arbitrary code execution by triggering a race condition between device deregistration and pkey change events, leading to dereferencing of a freed pointer. This can be accomplished by continuously sending P_Key table update events from an unauthenticated node on the same InfiniBand subnet while the device is being unregistered.
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
