The Centos security team deemed this advisory irrelevant for Centos:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-abi-stablelists package and not the kernel-abi-stablelists package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: check num_entries in GEM_OP GET_MAPPING_INFO
kvcalloc(args->num_entries, sizeof(*vm_entries), GFP_KERNEL) at amdgpu_gem.c:1050 uses the user-supplied num_entries directly without any upper bounds check. Since num_entries is a __u32 and sizeof(drm_amdgpu_gem_vm_entry) is 32 bytes, a large num_entries produces an allocation exceeding INT_MAX, triggering WARNING in __kvmalloc_node_noprof(), causing a kernel WARNING, TAINT_WARN, and panic on CONFIG_PANIC_ON_WARN=y systems.
Add a size bounds check before we invoke the kvzalloc() to reject oversized num_entries early with -EINVAL.
(cherry picked from commit 1fe7bf5457f6efd7be60b17e23163ba54341d73d)
