Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: usbnet: ipheth: Fixed the DPE OoB read issue. A buffer-overflow vulnerability related to DPE reads has been addressed. The number of DPEs processed is limited to the amount that fits within the fixed-size NDP16 header...

The vulnerability of the ipheth_rcvbulk_callback() function in the Linux kernel’s USB device driver support mechanism allows a hacker to induce a service failure.

The vulnerability of the iphethrcvbulkcallback function in the Linux kernel’s USB device driver support routine is related to improper disabling or release of resources. Exploiting this vulnerability could allow an attacker to cause a service failure...

SUSE CVE-2025-21742

In the Linux kernel, the following vulnerability has been resolved: usbnet: ipheth: use static NDP16 location in URB Original code allowed for the start of NDP16 to be anywhere within the URB based on the wNdpIndex value in NTH16. Only the start position of NDP16 was checked, so it was possible f...

SUSE CVE-2025-21743

In the Linux kernel, the following vulnerability has been resolved: usbnet: ipheth: fix possible overflow in DPE length check Originally, it was possible for the DPE length check to overflow if wDatagramIndex + wDatagramLength U16MAX. This could lead to an OoB read. Move the wDatagramIndex term t...

CVE-2025-21742

CVE-2025-21742 affects the Linux kernel’s usbnet: ipheth handling within URB buffers. The vulnerability arose because the start of the NDP16 block could be placed anywhere in the URB based on wNdpIndex, allowing the fixed-length portion of NDP16 to extend past the URB end and trigger an OoB read....
