Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s powerpc/rtas component where the
rtas os term() function, called during kernel panic, could potentially hang the system if devtree lock is held. This occurs due to device tree lookups within the function, which involve locking and local IRQ state changes. The issue is addressed by caching relevant device tree characteristics at boot time, avoiding lookups during panic. The lookup for "ibm,extended-os-term" is converted to of property read bool() as it is a boolean property.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
