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.

Overview
Affected versions of this package are vulnerable to Buffer Overflow in the deferred_grow_zone process due to improper handling of the first_deferred_pfn update, which can result in an out-of-range value. An attacker can trigger a kernel panic or potentially execute arbitrary code by causing the system to initialize memory maps with misaligned or large contiguous memory allocations, especially when specific kernel configurations are enabled.
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
