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,...

EUVD-2026-85938

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: use skbget instead of skbclone for reqskb BT enable fails intermittently with -ETIMEDOUT -110.

CVE-2026-80977

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: don't touch shared zerocopy state in skbtxerror skbtxerror completes the zerocopy uarg and clears SKBFLALLZEROCOPY, and skbzcopydowngrademanaged clears SKBFLMANAGEDFRAGREFS. Both live in skbshinfo, which every clone...

CVE-2026-80977

CVE-2026-80977 affects the Linux kernel networking subsystem , specifically the skb_tx_error() function in the skbuff layer. When a cloned socket buffer is processed, skb_tx_error() prematurely clears shared zerocopy state (SKBFL_ALL_ZEROCOPY) and drops SKBFL_SHARED_FRAG while the original skb is...
