7.5 · HIGH
Published Apr 17, 2024 linux CWE-476 EPSS 0.69% (50th pctl)

Overview

CVE-2024-26881 is a high-severity vulnerability affecting linux linux_kernel. It was published on April 17, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

net: hns3: fix kernel crash when 1588 is received on HIP08 devices

The HIP08 devices does not register the ptp devices, so the

hdev->ptp is NULL, but the hardware can receive 1588 messages,

and set the HNS3_RXD_TS_VLD_B bit, so, if match this case, the

access of hdev->ptp->flags will cause a kernel crash:

[ 5888.946472] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000018

[ 5888.946475] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000018
