Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.4.0-rc3
Description
A use-after-free issue exists in the Linux kernel related to the handling of OPP (Operational Power Policy) tables after probe deferral. Specifically, when
dev pm opp of find icc paths() in allocate opp table() returns -EPROBE DEFER, the OPP table may be freed prematurely. If the OPP table is already added to the global lazy opp tables list, subsequent access can lead to a kernel crash. This occurs because the error path does not remove the table from the list before it is freed. The issue manifests as a kernel NULL pointer dereference during iteration over OPP tables that have already been freed, specifically within the of add opp table v2 function.Recommendations
Update to Linux kernel version 6.4.0-rc3 or later.
