CVE-2026-68129

A flaw was found in the Linux kernel's gve driver. Under extreme memory pressure, the driver's receive Rx buffer refill process can fail, causing the number of buffers available to hardware to drop below a critical threshold. This can lead to a permanent network queue stall, where the device drop...

CVE-2026-68135

A flaw was found in the Linux kernel's hip04 network driver. This vulnerability occurs when the buildskb function fails during the hip04rxpoll operation. The driver incorrectly proceeds without releasing the network receive RX buffer and its associated Direct Memory Access DMA mapping. This leads...

CVE-2026-68124

Summary (CVE-2026-68124): In the Linux kernel’s MCTP serial path (mctp_serial_tty_receive_buf), a zero-length frame could cause an out-of-bounds heap write when rxlen is 0 and the parser enters STATE_DATA, allowing attacker-controlled writes after CAP_NET_ADMIN attaches the mctpserial netdev. The...

CVE-2026-64339

CVE-2026-64339 affects the Linux kernel USB IO stack (usbio_bulk_msg). A malicious device that advertises a large bulk OUT and small bulk IN endpoint can set bpkt_len (from bpkt->len) to exceed rxbuf_len, causing memcpy to read past rxbuf and leak adjacent slab memory via i2c-dev. The code alr...
