CVE-2025-21901

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Add sanity checks on rdev validity There is a possibility that ulp_irq_stop and ulp_irq_start callbacks will be called when the device is in detached state. This can cause a crash due to NULL pointer dereference as the rdev is already freed.
