Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved, related to the regulator max20086. The issue involves invalid memory access when the device fails to probe, resulting in a call to of node put() on a stack pointer that is out of scope. This generates error messages, including a stack trace. The problem arises from the allocation of the matches array on the stack, which is then populated into a struct devm of regulator matches. To fix this, the matches array is now allocated using devm kcalloc(), preventing access to the stack pointer after it has gone out of scope.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
