CVE-2022-50830

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the hd44780 remove() function within the hd44780 driver for LCD displays. The hd44780 probe() function allocates memory using kzalloc() and assigns the address to lcd->drvdata->hd44780. However, this memory is not released in hd44780 remove(), resulting in a memory leak. Releasing lcd->drvdata->hd44780 in hd44780 remove() resolves this issue.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
