CVE-2023-52879

The CVE-2023-52879 issue concerns the Linux kernel tracing subsystem, specifically the trace_event_file object used for tracefs events. A use-after-free can occur when a kprobe event is deleted while a user-space process still holds an opened “enable” file descriptor for that event, because the u...

CVE-2021-47274

CVE-2021-47274 (Linux kernel tracing): The issue stems from a length check in tracing that can cause memory corruption in ftrace data, leading to kernel crashes. A fix was added (commit b220c049d519) to validate the length before exposing the trace buffer, addressing overflow introduced by a prio...
