Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the drm/amdgpu subsystem where the number of BO list entries is not limited. Userspace can provide an arbitrary number of BO list entries via the
bo number field. While a previous check prevents out-of-bounds allocation, a large number of entries can lead to excessive memory allocation, potentially reaching gigabytes, and prolonged list processing times. A limit of 128k entries per BO list has been introduced to prevent resource exhaustion and maintain predictable performance. The function returns -EINVAL if the entry count exceeds this limit.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
