CVE-2026-46147

In CVE-2026-46147, the Linux kernel KVM arm64 vCPU initialization had two bugs: (1) after hyp_pin_shared_mem() succeeds, an early error path could jump to unlock and leak host pin references for vCPU and SVE state pages because unpin_host_vcpu()/unpin_host_sve_state() weren’t called; a fix extrac...

PT-2026-44270

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description Two issues exist in the vCPU initialization path of the KVM arm64 component. First, a failure occurring after hyp pin shared mem succeeds can lead to a pin leak, where pin references on...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...
