Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the UFS core tracing mechanism where trace events in drivers/ufs/core/ufs trace.h incorrectly dereference pointers within the TP printk() function. Specifically, the system attempts to print the dev name by dereferencing a saved hba pointer. Because TP printk() is executed only when the trace event is read from the /sys/kernel/tracing/trace file—which may occur long after the event was recorded—the hba pointer may no longer be valid. This illegal dereference of a freed pointer can lead to a kernel crash.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
