VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A memory leak exists in the s3c24xx serial getclk() function when iterating through clocks. The issue occurs when searching for the best clock; if a better match is found, the previously allocated clock is not freed, leading to a memory leak. If a better match is already found, the new one still needs to be freed to prevent the leak.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
