kernel: vmwgfx: double free within the handling of vmw_buffer_object objects

A double-free vulnerability was found in handling vmwbufferobject objects in the vmwgfx driver in the Linux kernel. This issue occurs due to the lack of validating the existence of an object prior to performing further free operations on the object, which may allow a local privileged user to...

kernel: nfsd: call op_release, even when op_func returns an error

In the Linux kernel, the following vulnerability has been resolved: nfsd: call oprelease, even when opfunc returns an error For ops with "trivial" replies, nfsd4encodeoperation will shortcut most of the encoding work and skip to just marshalling up the status. One of the things it skips is callin...

kernel: RDMA/rxe: Fix mr->map double free

A double-free vulnerability was found in the Linux kernel RDMA RXE soft-RoCE driver's memory region handling. A local user with access to RDMA userspace verbs can register a memory region with parameters that cause initialization to fail, triggering error handling code that frees the mr-map...

kernel: SUNRPC: double free xprt_ctxt while still in use

A flaw was addressed in the Linux kernel’s SUNRPC implementation affecting deferred RPC request handling. When an RPC request is deferred, the internal rqxprtctxt pointer is moved from the active service request to a deferred request structure. Under certain rare conditions where a request is...
