In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Add upper bound check for num_of_nodes drm/amdkfd: Add upper bound… (CVE-2026-53376)
A vulnerability in the Linux kernel's drm/amdkfd component was resolved by adding an upper bound check for the num_of_nodes parameter in the kfd_ioctl_get_process_apertures_new function. This fix prevents potential issues caused by unchecked values of num_of_nodes.
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in the drm/amdkfd driver where the num_of_nodes parameter in the kfd_ioctl_get_process_apertures_new ioctl call lacked an upper bound check. This could lead to improper handling of this parameter. The issue was fixed by adding an upper bound check to ensure num_of_nodes does not exceed expected limits, preventing potential memory or logic errors.
Potential Impact
The vulnerability could allow improper processing of the num_of_nodes parameter, potentially leading to memory corruption or other unintended behavior within the kernel's AMD KFD driver. No known exploits in the wild have been reported. The exact impact severity is not specified.
Mitigation Recommendations
An official fix has been applied to the Linux kernel by adding an upper bound check for num_of_nodes in the drm/amdkfd driver. Users should update their Linux kernel to a version that includes this fix. Patch status is confirmed by the vendor commit referenced. No additional mitigation actions are indicated.
