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