UBUNTU-CVE-2026-98751

In the Linux kernel, the following vulnerability has been resolved: tty: abort break signalling on hangup The break ioctls can race with hangup and end up calling into a tty driver for a device that is already gone or powered down. Drivers must handle this race, but TCSBRK and TCSBRKP should stil...

UBUNTU-CVE-2026-98731

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintelpcie: fix plen overflow in btintelpcierecvframe plen is u16 and computed as HDRSIZE + dlen. For ACL/ISO frames dlen is a 16-bit field, so a value = 0xFFFC wraps the sum, bypassing the "skb-len plen" check and...
