CVE-2022-48995
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
Input: raydium_ts_i2c - fix memory leak in raydium_i2c_send()
There is a kmemleak when test the raydium_i2c_ts with bpf mock device:
After BANK_SWITCH command from i2c BUS, no matter success or error happened, the tx_buf should be freed.
