CVE-2026-98754

In the Linux kernel, the following vulnerability has been resolved: tty: vcc: hold port lock when clearing tty pointer in vcccleanup vcccleanup sets port-tty to NULL without holding port-lock, racing with vccevent LDC callbacks that read port-tty under port-lock and then use tty-port. This can...

CVE-2026-98755

In the Linux kernel, the following vulnerability has been resolved: tty: vcc: zero-initialize control packet in vccsendctl The stack-allocated struct viovcc pkt was partially initialized, leaving the tag.stypeenv field uninitialized before being sent via ldcwrite, potentially leaking kernel stack...

CVE-2026-98755

A vulnerability exists in the Linux kernel within the tty: vcc component. The vcc_send_ctl() function fails to fully zero-initialize the stack-allocated struct vio_vcc pkt structure. Specifically, the tag.stype_env field remains uninitialized before being transmitted via ldc_write(), which can re...

CVE-2026-98754

The Linux kernel contains a vulnerability in the tty subsystem where the vcc_cleanup() function sets port->tty to NULL without holding the port->lock . This creates a race condition with vcc_event() LDC callbacks, which read port->tty under the lock and subsequently use tty->port . Th...
