Summary (CVE-2026-23061) : The Linux kernel CAN subsystem can: kvaser_usb_read_bulk_callback() leak URBs in kvaser_usb, leading to a memory leak. Root cause: the URBs for USB-in transfers are anchored to dev->rx_submitted when created and submitted, but the USB framework unanchors URBs before ...

CVE-2026-23057

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Coalesce only linear skb vsock/virtio common tries to coalesce buffers in rx queue: if a linear skb with a spare tail room is followed by a small skb length limited by GOODCOPYLEN = 128, an attempt is made to join...

kernel: net: atlantic: fix fragment overflow handling in RX path

An out-of-bounds write vulnerability was found in the Aquantia Atlantic network driver in the Linux kernel. When receiving packets that span more than MAXSKBFRAGS 17 fragments, the driver writes beyond the skb fragment array bounds in skbaddrxfrag, causing kernel memory corruption and panic...
