Design/Logic Flaw

A use-after-free flaw was found in kernel/trace/ringbuffer.c in Linux kernel before 5.10-rc1. There was a race problem in traceopen and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem DOS. This flaw could even allow a local attacker with special use...
