The US government is warning that a Linux flaw introduced more than a decade ago – and fixed more than a year ago – is being actively used in ransomware attacks. In February 2014, a vulnerability was introduced into the Linux kernel via a commit.
The bug was first disclosed in late January 2024, and described as a “use-after-free weakness in the netfilter: nf_tables kernel component”. It was fixed later that month, and was given a label CVE-2024-1086. Its severity score is 7.8/10 (high) and can be exploited to achieve local privilege escalation.
