CVE-2024-42147 Information

Description

In the Linux kernel the following vulnerability has been resolved:

crypto: hisilicon/debugfs - Fix debugfs uninit process issue

During the zip probe process the debugfs failure does not stop the probe. When debugfs initialization fails jumping to the error branch will also release regs in addition to its own rollback operation.

As a result it may be released repeatedly during the regs uninit process. Therefore the null check needs to be added to the regs uninit process.
