## Overview

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

drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error

Ensure index in rtl2830_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.

## Affected

- `debian_linux = 11.0`
- `linux_kernel >= 4.0, < 4.19.323`
- `linux_kernel >= 4.20, < 5.4.285`
- `linux_kernel >= 5.5, < 5.10.227`
- `linux_kernel >= 5.11, < 5.15.168`
- `linux_kernel >= 5.16, < 6.1.113`
- `linux_kernel >= 6.2, < 6.6.54`
- `linux_kernel >= 6.7, < 6.10.13`
- `linux_kernel >= 6.11, < 6.11.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.11.2`
