Description
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.
Ubuntu-Description
It was discovered that the event tracing subsystem of the Linux kernel did
not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (kernel memory
exhaustion).
