CVE-2026-80826

CVE-2026-80826 is a use-after-free in the Linux kernel's c67x00 USB driver , specifically in c67x00_add_iso_urb(). When TD creation fails for the last packet of an isochronous URB, the driver gives the URB back before updating the endpoint scheduling state. Since c67x00_giveback_urb() frees the U...

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: ensure tx headroom in usbsdiotxprepareskb mt7925usbsdiotxprepareskb pushes a TX descriptor and a USB header onto every skb and assumes the headroom for them is already there. That holds for locally generated...

CVE-2026-80825

CVE-2026-80825 affects the Linux kernel mt76 WiFi driver for mt7925 USB/SDIO devices (mt7925u). The function mt7925_usb_sdio_tx_prepare_skb() pushes a TX descriptor and USB header onto every skb, assuming sufficient headroom is already present. This assumption holds for locally generated traffic ...

CVE-2026-80824

CVE-2026-80824 is a use-after-free in the Linux kernel's usbfs subsystem. In usbdev_release(), the reference to struct usb_device is dropped before draining completed async URBs; the drain path then dereferences the already-freed device via bus_to_hcd(ps->dev->bus) in dec_usb_memory_use_cou...

CVE-2026-80823

CVE-2026-80823 is a Linux kernel vulnerability in the nfc: st21nfca NFC driver. The function st21nfca_tm_recv_atr_req() validates that a received ATR_REQ frame meets a minimum size and that its self-declared length is at least the struct size, but never checks that the declared length does not ex...

CVE-2026-80822

CVE-2026-80822 affects the Linux kernel's mchp-ipc-sbi mailbox driver. The root cause is a missing null check on the return value of devm_kasprintf() in the function mchp_ipc_get_cluster_aggr_irq() . Without this check, a failed allocation could lead to a NULL pointer dereference. The fix adds a ...

CVE-2026-80821

CVE-2026-80821 affects the Linux kernel 's nvmet pci-epf driver (NVM Express over Fabrics Target, PCIe Endpoint Function). The vulnerability is a reference leak in nvmet_pci_epf_create_cq(): when PCI address-space mapping fails or returns a too-small partial mapping after nvmet_cq_create() succee...
