Linux · Linux Kernel · CVE-2024-26881
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The vulnerability is related to a NULL pointer dereference in the hns3 component of the Linux kernel. When a 1588 message is received on HIP08 devices, the `hdev->ptp` is NULL, but the hardware can still receive 1588 messages and set the `HNS3 RXD TS VLD B` bit. If this condition is met, accessing `hdev->ptp->flags` will cause a kernel crash. The vulnerability can be exploited to cause a denial of service.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
