CVE-2026-46189

In the Linux kernel, the following vulnerability has been resolved: RDMA/vmwpvrdma: Fix double free on pvrdmaallocucontext error path Sashiko points out that pvrdmauarfree is already called within pvrdmadeallocucontext, so calling it before triggers a double free...

CVE-2026-46189

CVE-2026-46189 affects the Linux kernel RDMA pvrdma component (pvrdma_alloc_ucontext). The issue is a double free: pvrdma_uar_free() is invoked in pvrdma_dealloc_ucontext() and is erroneously called before, creating a double free condition. Concrete fixes exist in OSV entries for multiple distrib...

CVE-2026-46176

The CVE-2026-46176 issue affects the Linux kernel RDMA mlx5 path (mlx5_ib_dev_res_srq_init): when ib_create_srq() fails for s1, the error path can end up with freed s0 and ERR_PTR s1 assigned to devr->s0/devr->s1, leading to use-after-free/double-free risk in subsequent access. The fix adds...
