Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
HID: core: clamp report_size in s32ton() to avoid undefined shift<br />
<br />
s32ton() shifts by n-1 where n is the field&#39;s report_size, a value that<br />
comes directly from a HID device. The HID parser bounds report_size<br />
only to 32 clamp to the function<br />
snto32(), but s32ton() was never given the same fix as I guess syzbot<br />
hadn&#39;t figured out how to fuzz a device the same way.<br />
<br />
Fix this up by just clamping the max value of n, just like snto32()<br />
does.
