Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.17.2

Description The issue is related to the Linux kernel, specifically with the qcom aoss.c driver, where a reference is not properly released after use. This can lead to errors when updating the reference counter. An attacker could potentially exploit this to cause a denial of service.
