CVE-2023-54026

Linux

In the Linux kernel, the following vulnerability has been resolved: opp: Fix use-after-free in lazy_opp_tables after probe deferral When dev_pm_opp_of_find_icc_paths() in _allocate_opp_table() returns -EPROBE_DEFER, the opp_table is freed again, to wait until all the interconnect paths are available. However, if the OPP table is using required-opps then it may already have been added to the global lazy_opp_tables list. The error path does not remove the opp_table from the list again. This can cause crashes later when the provider of the required-opps is added, since we will iterate over OPP...
