一、漏洞信息
漏洞编号：CVE-2023-0030
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0
CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
A vulnerability was found in kernel, where a use-after-frees in nouveau s nvkm_vmm_pfn_map() could happen.Description of problem:Here is a function call chain. nvkm_vmm_pfn_map->nvkm_vmm_pfn_split_merge->nvkm_vmm_node_splitIf nvkm_vma_tail return NULL in nvkm_vmm_node_split, it will finally invoke nvkm_vmm_node_merge->nvkm_vmm_node_delete, whichwill free the vma. However, nvkm_vmm_pfn_map didn t notice that.It goes into next label and UAF happensHow reproducible:This bug is hard to trigger. It requires nvkm_vma_tail return NULL,which means kzalloc returns NULL.Steps to Reproduce:1.make a lot of memory allocation in Linux kernel so that to make kzalloc failed in nvkm_vma_tail 2.UAF happensReference:https://github.com/torvalds/linux/commit/729eba3355674f2d9524629b73683ba1d1cd3f10
