CVE-2022-23646 is a vulnerability found in the Linux kernel. This security flaw allows an attacker to gain elevated privileges on a targeted system, which can result in total control of the system. The vulnerability is due to a memory leak in the kernel's implementation of the stream control transmission protocol (SCTP) and affects all versions of the Linux kernel before 5.15.12.
The vulnerability was discovered by a researcher who reported it to the Linux security team in April 2022. The team quickly released a patch for the vulnerability, which was included in the Linux kernel version 5.15.12. The severity of this vulnerability is considered high, with a CVSS score of 7.8 out of a possible 10.
If left unpatched, attackers can exploit this vulnerability to execute arbitrary code with elevated privileges, leading to system compromise or data theft. Therefore, users are strongly encouraged to update their systems with the latest patched versions to prevent any potential attacks.
