CVE-2024-47663

17
FAUCET Score

CVE-2024-47663 is a division-by-zero vulnerability in the Linux kernel's ad9834 frequency driver, specifically within the ad9834_write_frequency() function. This flaw arises when clk_get_rate() returns zero, leading to a division by zero in ad9834_calc_freqreg(), which can be triggered by an unvalidated frequency parameter from user input. Rated Medium (CVSS 5.5), this vulnerability requires local access and low privileges (AV:L/PR:L) to cause a high impact on availability (A:H), potentially leading to a denial of service. There is currently no known active exploitation, public exploit code, or significant community discussion surrounding this CVE.
