What is CVE-2024-43822?

CVE-2024-43822 is a medium-severity vulnerability in Linux kernel, published on 17 Aug 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

In the Linux kernel, the following vulnerability has been resolved:

ASoc: PCM6240: Return directly after a failed devm_kzalloc() in pcmdevice_i2c_probe()

The value “-ENOMEM” was assigned to the local variable “ret” in one if branch after a devm_kzalloc() call failed at the beginning. This error code will trigger then a pcmdevice_remove() call with a passed null pointer so that an undesirable dereference will be performed. Thus return the appropriate error code directly.
