Description

From CVE.org

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.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
