- Summary
- mailbox: mchp-ipc-sbi: fix out-of-bounds access in mchp_ipc_get_cluster_aggr_irq()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mailbox: mchp-ipc-sbi: fix out-of-bounds access in mchpipcgetclusteraggr_irq()
The clustercfg array is dynamically allocated to hold per-CPU configuration structures, with its size based on the number of online CPUs. Previously, this array was indexed using hartid, which may be non-contiguous or exceed the bounds of the array, leading to out-of-bounds access. Switch to using cpuid as the index, as it is guaranteed to be within the valid range provided by foreachonlinecpu().
