CVE-2026-53002: Linux kernel network component can write past memory

CVE-2026-53002 · published 3 months ago

Summary

The Linux kernel's network tracking code could accidentally write data outside of its intended memory area, which could cause crashes or be exploited. This affects Canonical's Linux distributions, including standard, AWS, Azure, LTS Xenial, and AWS HWE versions. Update the kernel to the latest patched version provided by Canonical to eliminate the risk.
