CVE-2026-74459

CVE-2026-74459 (Linux kernel) affects the can: etas_es58x driver, specifically es58x_read_bulk_callback(). When RX URB resubmission fails (usb_submit_urb()), the callback currently does not release the allocated coherent transfer buffer, causing a buffer leak. The fixes documented in multiple sou...

CVE-2026-72064

In the Linux kernel, the following vulnerability has been resolved: net: mana: Sync page pool RX frags for CPU MANA allocates RX buffers from page pool fragments when fragcount is greater than 1. In that case the buffers remain DMA mapped by page pool and the RX completion path does not call...

CVE-2026-72064 net: mana: Sync page pool RX frags for CPU

In the Linux kernel, the following vulnerability has been resolved: net: mana: Sync page pool RX frags for CPU MANA allocates RX buffers from page pool fragments when fragcount is greater than 1. In that case the buffers remain DMA mapped by page pool and the RX completion path does not call...

CVE-2026-72064

CVE-2026-72064 relates to the Linux kernel net: mana RX path. When frag_count > 1, RX buffers are taken from page pool fragments and remain DMA mapped; the RX completion path did not call dma_unmap_single(), so the implicit CPU sync prior to handing data to the networking stack was missing. Th...

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

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

CVE-2026-68135 net: hip04: fix RX buffer leak on build_skb failure

In the Linux kernel, the following vulnerability has been resolved: net: hip04: fix RX buffer leak on buildskb failure When buildskb fails in hip04rxpoll, the driver jumps to the refill path without releasing the current RX buffer and its DMA mapping. Installing a replacement buffer then overwrit...

CVE-2026-68124

CVE-2026-68124 affects the Linux kernel MCTP serial driver. A zero-length frame could cause an out-of-bounds write in the receive path when rxlen == 0, requiring CAP_NET_ADMIN to attach the MCTP line discipline and bring up the netdev. The fix routes zero-length frames to STATE_TRAILER (instead o...

Linux Distros Unpatched Vulnerability : CVE-2026-68135

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: hip04: fix RX buffer leak on buildskb failure When buildskb fails in hip04rxpoll, the driver jumps to the refill path without releasing the current RX buff...

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...
