CVE-2024-47698

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

State: Published
Severity: 7.8 High
Published: Oct 21, 2024
Updated: Aug 5, 2026
Reserved: Sep 30, 2024

Description

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 rtl2832_pid_filter does not exceed 31 to prevent out-of-bounds access.

dev->filters is a 32-bit value, so set_bit and clear_bit 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, rtl2830_pid_filter -> rtl2832_pid_filter in logmsg]
