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