Unity Linux 20.1070a Security Update: kernel (UTSA-2025-383816)

high Nessus Plugin ID 267711

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-383816 advisory.

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]

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
