CVE-2022-50075

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the Linux kernel's tracing/eprobes, where using a symbol "@" with an event probe can cause a NULL pointer dereference crash. To resolve this, event probes are made consistent with kprobes and uprobes, allowing them to reference data beyond the main registers, such as immediate addresses, symbols, and the current task name. Specifically, for the "comm" field, if it is used and the event being attached to does not have this field, it defaults to "$comm" as in kprobes, consistent with histograms and filters.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
