In the Linux kernel, the following vulnerability has been resolved:
spi: fix use-after-free on controller registration failure
Make sure to deregister from driver core also in the unlikely event that per-cpu statistics allocation fails during controller registration to avoid use-after-free (of driver resources) and unclocked register accesses.
AnalysisAI
Use-after-free vulnerability in Linux kernel SPI controller registration allows local attackers to trigger unclocked register accesses and potential information disclosure when per-CPU statistics allocation fails during controller initialization. The vulnerability affects all Linux kernel versions and is fixed via proper driver core deregistration on allocation failure; no CVSS score or active exploitation data available at time of analysis.
