UBUNTU-CVE-2025-21780: Buffer Overflow

Q: What level of access does an attacker need?

The attacker needs local access with low privileges. Exploitation does not require user interaction.

Q: What input sequence triggers the overflow?

A malicious local user provides a small power-play table through sysfs and then provides a larger one. This can trigger a buffer overflow in smu_sys_set_pp_table().

Q: Which Ubuntu kernel package families are listed as affected?

The listed package families are linux, linux-fips, linux-azure, linux-gcp, linux-aws-fips, linux-azure-fips, linux-gcp-fips, and linux-realtime.

Published Feb 27, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: avoid buffer overflow attach in smusyssetpptable() It malicious user provides a small pptable through sysfs and then a bigger pptable, it may cause buffer overflow attack in function smusyssetpptable().

Frequently Asked Questions

What level of access does an attacker need?

The attacker needs local access with low privileges. Exploitation does not require user interaction.

What input sequence triggers the overflow?

A malicious local user provides a small power-play table through sysfs and then provides a larger one. This can trigger a buffer overflow in smu_sys_set_pp_table().

Which Ubuntu kernel package families are listed as affected?

The listed package families are linux, linux-fips, linux-azure, linux-gcp, linux-aws-fips, linux-azure-fips, linux-gcp-fips, and linux-realtime.
