Description OSIDB Bzimport 2026-05-28 11:04:39 UTC 
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.
