Action Type Old Value New Value Changed Description An issue was discovered in Sysdig through 0.24.2, as used in Falco through 0.14.0 and other products. A bypass allows local users to run malicious code without being detected because record_event_consumer in driver/main.c in sysdig-probe.ko (and falco-probe.ko) mishandles a free space calculation. An issue was discovered in Falco through 0.14.0. A missing indicator for insufficient resources allows local users to bypass the detection engine. -
