In the Linux kernel, the following vulnerability has been resolved:drm/buddy: Fix alloc_range() error handling codeFew users have observed display corruption when they bootthe machine to KDE Plasma or playing games. We have rootcaused the problem that whenever alloc_range() couldn tfind the required memory blocks the function was returningSUCCESS in some of the corner cases.The right approach would be if the total allocated sizeis less than the required size, the function shouldreturn -ENOSPC.
