CVE-2022-0435 is a high-severity stack overflow vulnerability in the Linux kernel's TIPC protocol, affecting products like Fedora, Red Hat, and NetApp. A remote attacker can trigger this flaw by sending a maliciously crafted packet with an excessive number of domain member nodes, leading to system crashes or potential privilege escalation. With a CVSS score of 8.8 (High) and an EPSS score indicating significant exploitability, this vulnerability poses a substantial risk. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered some community discussion and media coverage, suggesting awareness within the security community.
