UBUNTU-CVE-2024-56767: Null Pointer Dereference

Q: Who can trigger this issue?

An attacker needs local access and low-level privileges on an affected Ubuntu kernel. No user interaction is required.

Q: What conditions lead to the crash?

The failure occurs when the at_xdmac memset descriptor creation returns NULL, such as when an invalid length is supplied or when the channel's free descriptor list is empty because memory is exhausted. This can result in a kernel null pointer dereference and denial of service.

Q: Which Ubuntu kernel packages are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.

Published Jan 6, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: dmaengine: atxdmac: avoid nullprtderef in atxdmacprepdmamemset The atxdmacmemsetcreatedesc may return NULL, which will lead to a null pointer dereference. For example, the len input is error, or the atchan->freedescslist is empty and memory is exhausted. Therefore, add check to avoid this.

Frequently Asked Questions

Who can trigger this issue?

An attacker needs local access and low-level privileges on an affected Ubuntu kernel. No user interaction is required.

What conditions lead to the crash?

The failure occurs when the at_xdmac memset descriptor creation returns NULL, such as when an invalid length is supplied or when the channel's free descriptor list is empty because memory is exhausted. This can result in a kernel null pointer dereference and denial of service.

Which Ubuntu kernel packages are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.
