Descriptions
An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.
Se detectó un problema en el kernel de Linux versiones anteriores a 4.14.11. Una doble liberación puede ser causada por la función allocate_trace_buffer en el archivo kernel/trace/trace.c.
A flaw was found in the allocate_trace_buffer in kernel/trace/trace.c in the debug subsystem, when failure to allocate a dynamic percpu area, a resource cleanup is called. The pointer (buf->buffer) still holds the address and is not set to NULL, which can cause a use-after-free problem, leading to a dangling pointer issue.
