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 check for num_of_nodes in kfd_ioctl_get_process_apertures_new. (cherry picked from commit 98ff46a5ea090c14d2cdb4f5b993b05d74f3949f)
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in the drm/amdkfd subsystem where the function kfd_ioctl_get_process_apertures_new did not properly enforce an upper bound check on the num_of_nodes parameter. This could potentially lead to an availability impact. The vulnerability was addressed by adding the necessary upper bound validation, as indicated by the cherry-picked commit 98ff46a5ea090c14d2cdb4f5b993b05d74f3949f. No further technical details or exploit methods are provided.
Potential Impact
The vulnerability affects system availability, potentially causing denial of service conditions. There is no impact on confidentiality or integrity reported. No known exploits are currently in the wild.
Mitigation Recommendations
A fix has been applied to the Linux kernel drm/amdkfd component by adding an upper bound check for num_of_nodes. Users should update to a kernel version that includes this patch. Patch status is not explicitly confirmed in the provided data; therefore, check the official Linux kernel advisories or vendor sources for the exact fixed versions and apply updates accordingly.
