Threats Tagged 'cve-2023-2593'

CVE-2023-2593 is a medium-severity vulnerability in the Linux kernel related to TCP connection handling. It involves an infinite loop caused by a loop with an unreachable exit condition, leading to memory not being released after its effective lifetime. An unauthenticated attacker can exploit this flaw remotely to cause a denial of service (DoS) by exhausting system resources. The vulnerability does not impact confidentiality or integrity but severely affects availability. Exploitation requires network access but no authentication or user interaction. No known exploits are currently reported in the wild. The vulnerability affects Linux kernel versions prior to the patch and is relevant to systems heavily reliant on Linux servers. European organizations using Linux-based infrastructure, especially in countries with high Linux adoption in critical sectors, are at risk. Mitigation involves applying kernel patches once available, monitoring network traffic for abnormal connection patterns, and implementing rate limiting on TCP connections. Countries like Germany, France, the Netherlands, and the UK are likely most affected due to their extensive use of Linux in enterprise and government environments.
