CVE-2024-43822

Medium

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.
