Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a NULL pointer dereference in the
myrs detect() function of the Linux kernel's myrs component. When privdata->hw init() fails with a non-zero value, cs->disable intr is NULL, leading to a crash when myrs cleanup(cs) is called. This results in a kernel crash due to a NULL pointer dereference. The error is indicated by messages such as "Unknown Initialization Error 5A" and "Failed to initialize Controller." The call trace includes functions like myrs cleanup(), myrs probe.cold(), and local pci probe(). The vulnerability can be exploited to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
