Description OSIDB Bzimport 2025-04-01 16:01:38 UTC 
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.
