Overview

CVE-2024-53065 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 19, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

mm/slab: fix warning caused by duplicate kmem_cache creation in kmem_buckets_create

Commit b035f5a6d852 ("mm: slab: reduce the kmalloc() minimum alignment

if DMA bouncing possible") reduced ARCH_KMALLOC_MINALIGN to 8 on arm64.

However, with KASAN_HW_TAGS enabled, arch_slab_minalign() becomes 16.

This causes kmalloc_caches[*][8] to be aliased to kmalloc_caches[*][16],

resulting in kmem_buckets_create() attempting to create a kmem_cache for

size 16 twice. This duplication triggers warnings on boot:

[ 2.325108] ------------[ cut here ]------------

[ 2.325135] kmem_cache of name 'memdup_user-16' already exists

[ 2.325783] WARNING: CPU: 0 PID: 1 at mm/slab_common.c:107 __kmem_cache_create_args+0xb8/0x3b0
