5.5 · MEDIUMOverview
CVE-2022-49800 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 1, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix memory leak in test_gen_synth_cmd() and test_empty_synth_event()
test_gen_synth_cmd() only free buf in fail path, hence buf will leak
when there is no failure. Add kfree(buf) to prevent the memleak. The
same reason and solution in test_empty_synth_event().
