CVE-2022-48995

Kernel memory leak via unreleased I2C transmit buffers

Published Oct 21, 2024 · Updated May 11, 2026

Memory leak in the Raydium I2C touchscreen driver in Linux allows attackers to consume kernel memory when a BANK_SWITCH command is processed. The raydium_i2c_send function allocates tx_buf but fails to free it after BANK_SWITCH on both successful and failed transfers. Reachability requires the Raydium I2C driver and a command path to the device; the record demonstrates leaked allocations but documents no crash.
