In the Linux kernel, the following vulnerability has been resolved: xfrm: move policybydst RCU sync from per-netns .exit to .preexit The struct pernetoperations docstring in include/net/netnamespace.h explicitly warns against blocking RCU primitives in .exit handlers: Exit methods using blocking...

CVE-2026-64509

The CVE fixes a leak in the Linux kernel rust: block GenDisk cleanup paths. GenDiskBuilder::build() leaves fallible work after __blk_mq_alloc_disk() that can cause the temporary gendisk and request_queue to be retained until teardown, if the caller moves the last Arc<TagSet> into build(). T...

In the Linux kernel, the following vulnerability has been resolved: virtiopci: fix vq info pointer lookup via wrong index Unbinding a virtio balloon device: echo virtio0 /sys/bus/virtio/drivers/virtioballoon/unbind triggers a NULL pointer dereference. The dmesg says: BUG: kernel NULL pointer...

CVE-2026-64457

The CVE-2026-64457 issue affects the Linux kernel’s virtio_pci subsystem. When unbinding a virtio balloon device (e.g., echo virtio0 > /sys/bus/virtio/drivers/virtio_balloon/unbind), a NULL pointer dereference can occur due to a mismatch between sparse queue indices and dense queue indices (ho...

CVE-2026-64438 crypto: qat - fix VF2PF work teardown race in adf_disable_sriov()

In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix VF2PF work teardown race in adfdisablesriov The VF2PF interrupt handler queues PF-side response work that stores a raw pointer to per-VF state struct adfaccelvfinfo. Currently, adfdisablesriov destroys per-VF...

CVE-2026-64438

Summary of CVE-2026-64438 : In the Linux kernel’s crypto: qat path, a race during VF2PF teardown could cause use-after-free of per-VF state (vf_info) due to tearing down per-VF locks and state before in-flight VF2PF work completes. The fix introduces a PF-local flag (vf2pf_disabled) that gates wo...
