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-2026-53076 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.5, 5.10, 6.1.191, 6.6.141, 6.12.91, 6.18.33, 7.0.10 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-Bounds in the pcpu_init_value process. An attacker can disclose sensitive kernel memory and potentially cause a system crash or panic by creating a BPF map with a value size not aligned to 8 bytes, then copying data from a CGROUP_STORAGE map to a per-CPU map with the same unaligned value size. This is only exploitable if the attacker can load and execute BPF programs with access to create and manipulate BPF maps.
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
