Description
In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: avoid double free of pool->stack on AQ init failure otx2_pool_aq_init() frees pool->stack when mailbox sync or retry allocation fails, but leaves the pointer unchanged. Later, otx2_sq_aura_pool_init() unwinds the partial setup through otx2_aura_pool_free(), which frees pool->stack again. The CN20K-specific cn20k_pool_aq_init() implementation has the same bug in its corresponding error path. Set pool->stack to NULL immediately after the local free so the shared cleanup path does not free the same stack again while cleaning up partially initialized pool state. The bug was first flagged by an experimental anal
