gpu: host1x: Avoid stack over-read in debug output helpers<\/p>\n
host1x_debug_output() and host1x_debug_cont() used vsnprintf(), which
\nreturns the length the formatted string would have reached with an
\nunbounded buffer. That return value was passed straight to o->fn as
\nthe number of bytes to emit.<\/p>\n
This could cause a read past end of the output buffer if a call to
\nhost1x_debug_* produced a string longer than 256 bytes. This only
\naffected the debugfs files as the printk debug sink ignores the
\nnumber of bytes. In practice, this is very unlikely to occur.<\/p>\n
Fix by switching to vscnprintf(), which returns the number of bytes
\nactually written.<\/p>\n","protected":false},"excerpt":{"rendered":"
