VectorAV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1
Description A double free issue exists in the RDMA/vmw pvrdma component. The error path in the pvrdma alloc ucontext() function triggers this condition because pvrdma uar free() is called immediately before pvrdma dealloc ucontext(), which already performs the same operation.
Recommendations Update to kernel-devel-7.0.11-1.1 for openSUSE Tumbleweed. At the moment, there is no information about a newer version that contains a fix for this vulnerability for the Linux kernel.
