CVE-2021-28453 is a vulnerability that was discovered in April 2021 and affects the Linux kernel. This vulnerability is caused by a flaw in the implementation of the BPF (Berkeley Packet Filter) system, which can allow an attacker to execute arbitrary code with kernel-level privileges. The vulnerability has been assigned a CVSS score of 8.8 out of 10, indicating a high level of severity. The vulnerability was discovered by security researcher Adam Bohannon, who reported it to the Linux kernel security team. The team quickly released a patch for the vulnerability, which was included in the Linux kernel version 5.12.4. However, many systems may still be vulnerable if they have not yet applied the patch. If an attacker successfully exploits this vulnerability, they could gain full control over the affected system, potentially accessing sensitive data or executing malicious code. Therefore, it is essential for organizations running Linux systems to apply the patch as soon as possible and take other necessary measures to prevent exploitation of the vulnerability.
