Description

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

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
