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

Description The issue is related to the devm kzalloc function in the pcmdevice i2c probe component of the Linux kernel. It is associated with pointer dereference errors. Exploitation of this issue may allow an attacker to cause a denial of service. The error code -ENOMEM is assigned to the local variable ret after a devm kzalloc call fails, triggering a pcmdevice remove call with a null pointer, leading to an undesirable dereference.

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