UBUNTU-CVE-2026-46186

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: virtiobt: validate rx pkttype header length virtbtrxhandle reads the leading pkttype byte from the RX skb and forwards the remainder to hcirecvframe for every event/ACL/SCO/ISO type, without checking that the remaining...

CVE-2026-46186

Summary: CVE-2026-46186 affects the Linux kernel Bluetooth virtio_bt driver. The vulnerability arises in virtbt_rx_handle(), which reads the leading pkt_type byte from RX skb and forwards the rest to hci_recv_frame() for multiple packet types without validating that the remaining payload is large...

CVE-2026-46185

In the Linux kernel, the following vulnerability has been resolved: smb/client: fix out-of-bounds read in symlinkdata Since smb2checkmessage returns success without length validation for the symlink error response, in symlinkdata it is possible for iov-iovlen to be smaller than sizeofstruct...

CVE-2026-46185

The CVE-2026-46185 issue affects the Linux kernel SMB client. The root cause is insufficient length validation in smb2_check_message() when processing symlink error responses, allowing a symlink_data() path to read beyond the buffer if iov_len is smaller than the 64-byte SMB2 header and accessing...

CVE-2026-46146 ALSA: usb-audio: Avoid potential endless loop in convert_chmap_v3()

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Avoid potential endless loop in convertchmapv3 The convertchmapv3 has a loop with its increment size of csdesc-wLength, but we forgot to validate csdesc-wLength itself, which may lead to potential endless loop by...

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...
