kernel: tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() in case of error
In the Linux kernel, the following vulnerability has been resolved:
tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() in case of error
If clk_get_rate() fails, the clk that has just been allocated needs to be
freed.
A memory leak vulnerability was found in the Samsung serial TTY driver in the Linux kernel. In s3c24xx_serial_getclk(), when clk_get_rate() fails, the previously allocated clock resource is not freed, leading to a memory leak. Repeated failures can cause resource exhaustion.
Statement: This is a memory leak in the Samsung serial driver affecting ARM-based Samsung SoC platforms. The impact is limited to Samsung Exynos and S3C/S5P series devices.
