A flaw was found in the Linux kernel’s networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service. CREATE(Triage):(User=admin) CVE-2022-3586 (https://nvd.nist.gov/vuln/detail/CVE-2022-3586)
