CVE-2025-38186

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix double invocation of bnxt_ulp_stop()/bnxt_ulp_start() Before the commit under the Fixes tag below, bnxt_ulp_stop() and bnxt_ulp_start() were always invoked in pairs. After that commit, the new bnxt_ulp_restart() can be invoked after bnxt_ulp_stop() has been called. This may result in the RoCE driver's aux driver .suspend() method being invoked twice. The 2nd bnxt_re_suspend() call will crash when it dereferences a NULL pointer: (NULL ib_device): Handle device suspend call BUG: kernel NULL pointer dereference, address: 0000000000000b78 PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP PTI CPU: 20 UID: 0 PID: 181 Comm: kworker/u96:5 Tainted: G S 6.15.0-rc1 #4 PREEMPT(voluntary) Tainted: [S]=CPU_OUT_OF_SPEC Hardware name: Dell Inc.
