NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-kvm package and not the kernel-rt-debug-kvm package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path
Sashiko points out that pvrdma_uar_free() is already called within pvrdma_dealloc_ucontext(), so calling it before triggers a double free.
