What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should update to the fixed kernel version once it is released. Until then, avoid using the affected ad9832 frequency driver or restrict access to it to trusted users. Patch status is not explicitly confirmed in the provided data; check the official Linux kernel advisories or vendor updates for the exact fixed versions and apply the official fix when available.
Description
CVE-2024-50233 is a medium severity vulnerability in the Linux kernel's ad9832 frequency driver. It involves a division by zero error in the ad9832_calc_freqreg() function caused by clk_get_rate() returning zero. This occurs because the check in ad9832_write_frequency() does not handle the case when the frequency output (fout) is zero, which can be derived from untrusted text input. The flaw could lead to a kernel crash (denial of service).
