Linux Kernel up to 6.12.1 fastmap mm/slab_common.c alloc_ai privilege escalation

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.12.1. It has been classified as problematic. This affects the function alloc_ai of the file mm/slab_common.c of the component fastmap. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: ubi: fastmap: Fix duplicate slab cache names while attaching Since commit 4c39529663b9 ("slab: Warn on duplicate cache names when DEBUG_VM=y"), the duplicate slab cache names can be detected and a kernel WARNING is thrown out. In UBI fast attaching process, alloc_ai() could be invoked twice with the same slab cache name 'ubi_aeb_slab_cache', which will trigger following warning messages: kmem_cache of name 'ubi_aeb_slab_cache' already exists WARNING: CPU: 0 PID: 7519 at mm/slab_common.c:107 __kmem_cache_create_args+0x100/0x5f0 Modules linked in: ubi(+) nandsim [last unloaded: nandsim] CPU: 0 UID: 0 PID: 7519 Comm: modprobe Tainted: G 6.12.0-rc2 RIP: 0010:__kmem_cache_create_args+0x100/0x5f0 Call Trace: __kmem_cache_create_args+0x100/0x5f0 alloc_ai+0x295/0x3f0 [ubi] ubi_attach+0x3c3/0xcc0 [ubi] ubi_attach_mtd_dev+0x17cf/0x3fa0 [ubi] ubi_init+0x3fb/0x800 [ubi] do_init_module+0x265/0x7d0 __x64_sys_finit_module+0x7a/0xc0 The problem could be easily reproduced by loading UBI device by fastmap with CONFIG_DEBUG_VM=y. Fix it by using different slab names for alloc_ai() callers.
