CVE-2026-63974

CVE-2026-63974 affects the Linux kernel Bluetooth subsystem. The issue arises in hci_sync where HCI_CMD_DRAIN_WORKQUEUE must be set during device close because hci_dev_close_sync() can be invoked on a reset path, preventing timeouts from being queued while the hdev workqueue drains. The consequen...

CVE-2026-63918

CVE-2026-63918 documents a Linux kernel fix: l2tp_session_get_by_ifname previously used refcount_inc() while other getters used refcount_inc_not_zero(), risking use-after-free if a race during RC/Rcu grace period allowed a zero refcount. The change normalizes the getter to refcount_inc_not_zero()...

CVE-2026-63917

The CVE-2026-63917 entry describes a Linux kernel issue in vti6 where changing network namespaces (NETNS) after a tunnel is created can leave a stale netns reference, due to NETIF_F_NETNS_LOCAL being dropped from vti6 devices by commit 61220ab34948. This allows a vti6 tunnel to move across namesp...
