Doc Text:
A flaw was found in the Linux kernel. 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 rollback operations. As a result, it may be released repeatedly during the regs uninit process.

Description OSIDB Bzimport 2024-07-30 08:39:04 UTC 
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.
