UBUNTU-CVE-2024-47663: Medium severity ubuntu/linux vulnerability

Q: What access does an attacker need to trigger the issue?

The issue is locally exploitable and requires low privileges. No user interaction is required; the attacker must be able to supply a frequency value through the AD9834 driver’s write interface.

Q: Which systems are exposed?

Systems using an affected Ubuntu kernel package and the staging IIO frequency AD9834 driver are relevant. The listed package families include linux, linux-fips, linux-aws, linux-azure, linux-gcp, and their listed FIPS variants.

Q: What is the impact of successful exploitation?

A crafted frequency value can cause a division by zero when the clock rate is zero, resulting in a denial of service. The provided severity vector indicates no confidentiality or integrity impact.

Q: Is there a configuration-based mitigation if updates cannot be applied immediately?

The data identifies the AD9834 driver write path as the affected interface. Limiting untrusted local users’ ability to write frequency values through that interface can reduce exposure.

Published Oct 9, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: staging: iio: frequency: ad9834: Validate frequency parameter value In ad9834writefrequency() clkgetrate() can return 0. In such case ad9834calcfreqreg() call will lead to division by zero. Checking 'if (fout > (clkfreq / 2))' doesn't protect in case of 'fout' is 0. ad9834writefrequency() is called from ad9834write(), where fout is taken from text buffer, which can contain any value. Modify parameters checking. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Compensating control
In ad9834_write_frequency(), validate the frequency parameter and reject fout == 0; also handle clk_get_rate() returning 0 before ad9834_calc_freqreg() can perform a division.

Frequently Asked Questions

What access does an attacker need to trigger the issue?

The issue is locally exploitable and requires low privileges. No user interaction is required; the attacker must be able to supply a frequency value through the AD9834 driver’s write interface.

Which systems are exposed?

Systems using an affected Ubuntu kernel package and the staging IIO frequency AD9834 driver are relevant. The listed package families include linux, linux-fips, linux-aws, linux-azure, linux-gcp, and their listed FIPS variants.

What is the impact of successful exploitation?

A crafted frequency value can cause a division by zero when the clock rate is zero, resulting in a denial of service. The provided severity vector indicates no confidentiality or integrity impact.

Is there a configuration-based mitigation if updates cannot be applied immediately?

The data identifies the AD9834 driver write path as the affected interface. Limiting untrusted local users’ ability to write frequency values through that interface can reduce exposure.
