CVE-2026-93209

The Linux kernel contains a vulnerability in the Bluetooth hci_core component where BT enable fails intermittently with -ETIMEDOUT (-110) . The root cause is that hci_send_cmd_sync() uses skb_clone() to copy a sent command into hdev->req_skb ; under memory pressure, this clone operation fails,...

CVE-2025-21925

CVE-2025-21925 : In the Linux kernel, a vulnerability was fixed where skb_get() could be used before dev_queue_xmit() when a shared skb is processed (e.g., with IFF_TX_SKB_SHARING). The documented exploit path involves syzbot crashing a host via the llc_sap_action_send_test_c path, with the e1000...
