Linux Distros Unpatched Vulnerability : CVE-2026-80970

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ALSA: FCP: do not copy out an uninitialised init response fcpioctlinit allocates its response buffer with kmalloc and copies the whole buffer back to userspace...

CVE-2026-80970

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA FireWire Control Protocol FCP subsystem. This vulnerability allows a local attacker to trigger the copying of uninitialized kernel memory to userspace. By sending a specially crafted short or zero-length data stage duri...

CVE-2026-80970

CVE-2026-80970 affects the Linux kernel ALSA FCP USB audio driver. In fcp_ioctl_init(), the response buffer is allocated via kmalloc() without being zeroed. Because the step-0 USB control transfer does not set URB_SHORT_NOT_OK, a short or zero-length data stage is accepted as success, and snd_usb...

CVE-2026-74640

A flaw was found in the Linux kernel's ALSA FireWire Control Protocol FCP. An unprivileged process can trigger an out-of-bounds write by reading controls on /dev/snd/controlC0 after an oversized Level Meter map has been installed. This occurs because the fcpmeterctlget function writes beyond its...
