CVE-2026-46140

CVE-2026-46140 affects the Linux kernel Bluetooth btmtk driver. The wmt event handling in btmtk_usb_hci_wmt_sync() casts SKB data to btmtk_hci_wmt_evt structures (7/9 bytes) without ensuring sufficient payload, risking out-of-bounds reads from SKB tailroom when a short firmware response is receiv...

CVE-2026-46123

Summary: CVE-2026-46123 affects the Linux kernel Bluetooth virtio_bt driver. The issue arises when virtbt_rx_work() skb_put(skb, len) uses an unvalidated len sourced from virtqueue_get_buf(), with the device exposing a 1000-byte RX buffer. Since alloc_skb() tailroom can exceed 1000, a malicious/b...

kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...
