Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ptp: ocp: Limit signal/freq counts in summary output functions<br />
<br />
The debugfs summary output could access uninitialized elements in<br />
the freq_in[] and signal_out[] arrays, causing NULL pointer<br />
dereferences and triggering a kernel Oops (page_fault_oops).<br />
This patch adds u8 fields (nr_freq_in, nr_signal_out) to track the<br />
number of initialized elements, with a maximum of 4 per array.<br />
The summary output functions are updated to respect these limits,<br />
preventing out-of-bounds access and ensuring safe array handling.<br />
<br />
Widen the label variables because the change confuses GCC about<br />
max length of the strings.
