CVE-2022-50087

HIGH

Linux Kernel 4.4-5.19.2 - Use-After-Free in SCP Interface Probe

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails When scpi probe fails, at any point, we need to ensure that the scpi_info is not set and will remain NULL until the probe succeeds. If it is not taken care, then it could result use-after-free as the value is exported via get_scpi_ops() and could refer to a memory allocated via devm_kzalloc() but freed when the probe fails.
