CVE-2022-1195 is a use-after-free vulnerability in the Linux kernel's hamradio drivers, specifically affecting Debian and other Linux distributions. A local attacker with user privileges can trigger a denial of service by detaching mkiss or sixpack devices and prematurely reclaiming resources. With a CVSS score of 5.5 (Medium), this flaw requires local access and has a high impact on availability, but does not affect confidentiality or integrity. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
