Threats tagged 'ghsa-hqr3-rh3c-f6xh'

A vulnerability in the Linux kernel tracing subsystem allows incorrect modification of synthetic event reference counts due to insufficient verification of event identity. This can lead to use-after-free conditions where a synthetic event is freed while still referenced by an active histogram action. The issue arises when histograms are registered or removed on non-synthetic events with basenames matching synthetic events, causing erroneous reference count decrements.
