Description
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.
Affected configurations
• linux linux kernel (>= 2.6.39 <= 5.19)
• linux linux kernel 6.0
• debian debian linux 10.0
