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 DoS (memory consumption).

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1774947]

Comment 2 Evgenii Shatokhin 2019-11-22 16:06:01 UTC

Is there a way for an unprivileged user to trigger this memory leak?
