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.

Affected products

Linux kernel: from 6.10 before 6.10.3 — fixed in 6.10.3

How to fix

Upgrade to a fixed version: Linux kernel 6.10.3. Check the vendor advisory for mitigations.
