CVE-2026-80971

CVE-2026-80971 is a use-after-free vulnerability in the ALSA bcd2000 driver (snd_bcd2000) of the Linux kernel. On USB device disconnect, bcd2000_free_usb_related_resources() frees both MIDI URBs without clearing the pointers. A still-open rawmidi substream can then access the freed URBs via the t...

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-2026-80947

CVE-2026-80947 is a use-after-free in the Linux kernel's rtl8xxxu Wi-Fi USB driver. During teardown, rtl8xxxu_stop() failed to cancel the rx_urb_wq worker, so a worker armed by active RX traffic could dereference freed priv after ieee80211_free_hw() freed it. Two races existed: schedule_work() wa...
