CVE-2026-98757 usb: cdns3: fix use-after-free in cdns3_gadget_exit()

In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: fix use-after-free in cdns3gadgetexit cdns3gadgetstart arms two works on systemfreezablewq: pendingstatuswq for the deferred ep0 status stage and alignedbufwq for realigned request buffers. Both handlers use the...

CVE-2026-98757

The Linux kernel contains a use-after-free vulnerability in the cdns3 gadget driver. The issue originates in cdns3_gadget_exit(), which fails to wait for two specific works (pending_status_wq and aligned_buf_wq) queued on system_freezable_wq. Because the function proceeds to free endpoints, buffe...

CVE-2026-98755 tty: vcc: zero-initialize control packet in vcc_send_ctl()

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 tty: vcc: hold port lock when clearing tty pointer in vcc_cleanup

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-2026-98754

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...

CVE-2026-98753

The Linux kernel contains a vulnerability in the tty_port component where the TTY_IO_ERROR flag is not restored upon activation failure. This oversight creates a race condition during tty ioctl , hangup, and open operations. If activation fails, the lack of this flag can lead to I/O attempts on p...
