CVE-2026-64222

CVE-2026-64222 affects the Linux kernel on OcteonTX2/CN20K: a double-free in pool->stack during AQ pool init cleanup. The otx2_pool_aq_init() path frees pool->stack on mailbox sync/retry failure but doesn’t null the pointer, causing otx2_sq_aura_pool_init() cleanup (via otx2_aura_pool_free(...

CVE-2026-64222 octeontx2-pf: avoid double free of pool->stack on AQ init failure

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: avoid double free of pool-stack on AQ init failure otx2poolaqinit frees pool-stack when mailbox sync or retry allocation fails, but leaves the pointer unchanged. Later, otx2sqaurapoolinit unwinds the partial setup...
