| Rohit Keshri | 2020-12-10 17:38:13 UTC | Doc Text | A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel. There was a race problem in trace_open 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 user privilege to a kernel information leak threat. | |
