The US Cybersecurity and Infrastructure Security Agency (CISA) has added a Linux kernel vulnerability to the Known Exploited Vulnerabilities (KEV) catalog, reports Steven J. Vaughan-Nichols.

CVE-2024-1086, a “use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component, can be exploited to achieve local privilege escalation,” according to NIST.
