CVE-2021-36367

CVE-2021-36367 is a vulnerability that was discovered in June 2021, affecting the Linux kernel's filesystem layer. The flaw allows attackers to gain elevated privileges and execute arbitrary code on affected systems. This vulnerability is particularly concerning as it can be exploited remotely, giving attackers the ability to exploit unpatched systems from anywhere in the world. The vulnerability was introduced in the Linux kernel version 5.7 and affects all subsequent versions up to version 5.12.13. A patch for the vulnerability was issued by the Linux kernel development team on June 30, 2021. However, due to the widespread use of the Linux operating system, it is likely that many systems remain vulnerable, making this a significant threat to cybersecurity. It is important for organizations using Linux-based systems to ensure that they have applied the necessary patches to protect against this vulnerability. Additionally, users should be vigilant for any suspicious activity on their systems, as attackers may have already exploited this vulnerability before the patch was released.
