CVE-2024-42223

Service interruption via tuner frequency multiplication overflow

Published Jul 30, 2024 · Updated May 11, 2026

Integer overflow in the Linux tda10048 DVB frontend driver allows local users to interrupt service during tuner configuration. In tda10048_set_if(), a 32-bit multiplication of state->xtal_hz, which can reach 16 MHz, by pll_mfactor wraps before the PLL value is derived. The driver and compatible DVB hardware must be present; published impact is limited to availability, with no reported data disclosure or modification.
