CVE-2026-64071

The CVE-2026-64071 issue is a use-after-free in the Linux kernel nvme-pci path. In nvme_free_host_mem(), dev->hmb_sgt is freed via dma_free_noncontiguous() but the pointer is not cleared, so a second call in the nvme_probe() error path (nvme_setup_host_mem() succeeds, nvme_set_host_mem() fails...

In the Linux kernel, the following vulnerability has been resolved: drm/msm/adreno: fix userspace-triggered crash on a2xx-a4xx Before a5xx Adreno driver will not try fetching UBWC params because those generations didn't support UBWC anyway, however it's still possible to query UBWC-related params...

CVE-2026-64048

The CVE-2026-64048 issue is in the Linux kernel SMC-D client (net/smc). A remote peer can reply with CHID 0 to a SMC-Dv2 proposal, matching an empty ism_dev slot and causing ini->ism_selected to 0. This can lead to a NULL pointer dereference in smc_conn_create() when dereferencing ism_dev[0]-&...
