CVE-2023-54282

Kernel crash via QT1010 terminal-entry BUG_ON

Published Dec 30, 2025 · Updated Dec 30, 2025

Kernel DoS in the QT1010 tuner driver in Linux 4.2 through 6.5.4 allows local users to crash the host during tuner initialization. In qt1010_init, a terminal QT1010_M1 table entry reaches BUG_ON rather than returning an I/O error before the code accesses the following i2c_data element. The shipped table ends with a write operation, and public sources do not identify an attacker-controlled method for placing QT1010_M1 in the terminal slot.
