UBUNTU-CVE-2025-68819: High severity ubuntu/linux vulnerability

Published Jan 13, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved: media: dvb-usb: dtv5100: fix out-of-bounds in dtv5100i2cmsg() rlen value is a user-controlled value, but dtv5100i2cmsg() does not check the size of the rlen value. Therefore, if it is set to a value larger than sizeof(st->data), an out-of-bounds vuln occurs for st->data. Therefore, we need to add proper range checking to prevent this vuln.

Compensating control
Add range checking in dtv5100_i2c_msg() to ensure the user-controlled rlen value does not exceed sizeof(st->data).

Frequently Asked Questions

What systems are realistically exposed to this issue?

The affected Ubuntu kernel packages listed are linux, linux-fips, linux-aws, linux-azure, linux-aws-fips, linux-azure-fips, linux-gcp, and linux-gcp-fips. Exposure also depends on use of the DVB USB dtv5100 driver and an interface through which a user can control the I2C read-length value.

What does an attacker need to control to trigger the flaw?

An attacker needs to supply an rlen value to dtv5100_i2c_msg() that exceeds the size of the driver's st->data buffer. The description identifies rlen as user-controlled and states that the missing bounds check leads to an out-of-bounds condition.

How can administrators determine whether their environment may be affected?

Identify whether the running Ubuntu system uses one of the listed kernel package variants and whether the dtv5100 DVB USB driver is present or used. The provided data does not include affected or fixed package versions.
