Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error<br /> <br /> Ensure index in rtl2830_pid_filter does not exceed 31 to prevent<br /> out-of-bounds access.<br /> <br /> dev-&gt;filters is a 32-bit value, so set_bit and clear_bit functions should<br /> only operate on indices from 0 to 31. If index is 32, it will attempt to<br /> access a non-existent 33rd bit, leading to out-of-bounds access.<br /> Change the boundary check from index &gt; 32 to index &gt;= 32 to resolve this<br /> issue.
