A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.
The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
