CVE-2026-68394

In CVE-2026-68394, the Linux kernel Bluetooth MGMT path had a use-after-free in conn_update_sync triggered by MGMT_OP_LOAD_CONN_PARAM queuing a param update. The queued work incorrectly kept a borrowed hci_conn_params pointer; if userspace freed the entry before the callback ran, a use-after-free...

CVE-2026-68329

CVE-2026-68329 affects the Linux kernel’s iommu/amd path. A race in iommu_completion_wait() can cause it to return before all previously queued commands complete, enabling a use-after-free window where stale page-table translations may be used. The issue stems from need_sync being read locklessly...

CVE-2026-68231

The CVE-2026-68231 issue affects the Linux kernel media stack, specifically the airspy driver under vb2. It occurs when start_streaming() returns an error without draining buffers that were already queued via buf_queue(); this can leave buffers leaked and trigger a WARN_ON(owned_by_drv_count) in ...
