Type:
CWE-787
Out-of-bounds Write
Publication date:

Last modified:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error<br />
<br />
Ensure index in rtl2832_pid_filter does not exceed 31 to prevent<br />
out-of-bounds access.<br />
<br />
dev->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 > 32 to index >= 32 to resolve this<br />
issue.<br />
<br />
[hverkuil: added fixes tag, rtl2830_pid_filter -> rtl2832_pid_filter in logmsg]
