CVE-2026-74543
CVE-2026-74543 concerns the Linux kernel UDP tunnel NIC offload code. The issue: when device registration fails, the code may leak a struct udp_tunnel_nic due to an early return if utn->work_pending is set, because no subsequent NETDEV_UNREGISTER rebroadcast occurs. The fix, as described in co...
CVE-2026-74542
CVE-2026-74542: In the Linux kernel netfs subsystem, a memory allocation path for folio_queue in writeback could fail, triggering ENOMEM. The fix adds a mempool and passes GFP flags to rolling buffer allocations, using the mempool if GFP_KERNEL is not used, and propagates the chosen GFP from netf...
CVE-2026-74541
CVE-2026-74541 relates to the Linux kernel Bluetooth ISO path. The vulnerability arises when detaching a connection from hcon without clearing conn->hcon->iso_data, leading to a use-after-free in iso_conn_free() and potential UAF unless iso_data is cleared. The fixed sequence clears iso_dat...

CVE-2026-74540
CVE-2026-74540 affects the Linux kernel Bluetooth L2CAP stack. The vulnerability arises in l2cap_le_connect_rsp() where a channel is obtained via __l2cap_get_chan_by_ident() without holding a reference; a concurrent remote disconnect could free the channel before l2cap_chan_lock(), causing a use-...
