Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.16.11

Description The issue is related to a memory leak in the Linux kernel, specifically in the drivers/hid/hid-elo.c component. This memory leak occurs under certain error conditions related to hid parse. Exploitation of this issue could allow an attacker to cause a denial of service.

Recommendations For Linux kernel versions prior to 5.16.11, update to version 5.16.11 or later to resolve the memory leak issue. As a temporary workaround, consider restricting access to the vulnerable hid-elo.c driver to minimize the risk of exploitation.
