MediumCVSS 5.5/10Last modified Jul 30, 2026

Description

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.
