Summary
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:

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.
