CVE-2023-54298
Description
An error pointer dereference was found in the Intel Quark thermal driver. When alloc_soc_dts() fails and returns an error pointer, attempting to free it causes a kernel crash.
Statement
This affects Intel Quark SoC platforms only, which are embedded/IoT devices not commonly found in enterprise environments. The crash occurs only on allocation failure during thermal subsystem initialization.
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).
