What is CVE-2021-3600?

The eBPF implementation in the Linux kernel has a vulnerability related to the improper tracking of bounds information for 32-bit registers during division and modulus operations. A local attacker can exploit this flaw to potentially execute arbitrary code, posing a significant security risk. The flaw goes unnoticed in certain operations, which could allow for abnormal behavior or unauthorized access to sensitive operations within the kernel. Users and organizations running affected versions of the Linux kernel should ensure that they apply the latest patches to mitigate this risk.
