Summary
drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error
Details

In the Linux kernel, the following vulnerability has been resolved:

drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error

Ensure index in rtl2832pidfilter does not exceed 31 to prevent out-of-bounds access.

dev->filters is a 32-bit value, so setbit and clearbit functions should only operate on indices from 0 to 31. If index is 32, it will attempt to access a non-existent 33rd bit, leading to out-of-bounds access. Change the boundary check from index > 32 to index >= 32 to resolve this issue.

[hverkuil: added fixes tag, rtl2830pidfilter -> rtl2832pidfilter in logmsg]
