Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2023-53687 affects the Linux kernel and involves a memory leak vulnerability in the s3c24xxserialgetclk() function within the samsung_tty serial driver. The vulnerability was discovered and published to the NVD on October 7, 2025 (NVD).
Technical details
The vulnerability occurs in the tty serial samsung_tty component when searching for the best clk. When iterating over all possible clk options, if a better match is found, the previous clk needs to be freed. Additionally, if a better match has already been found, the new clk still needs to be freed to prevent memory leaks (NVD).
Impact
The vulnerability results in memory leaks in the Linux kernel's serial driver component, which could potentially lead to resource exhaustion over time (NVD).
Mitigation and workarounds
The vulnerability has been resolved in the Linux kernel through patches that properly handle memory management in the s3c24xxserialgetclk() function. Multiple kernel versions have received fixes as evidenced by the various commit references (NVD).
