  "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 (\u0022mm: slab: reduce the kmalloc() minimum alignment if DMA bouncing possible\u0022) 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 \u0027memdup_user-16\u0027 already exists [    2.325783] WARNING: CPU: 0 PID: 1 at mm/slab_common.c:107 __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.327957] Modules linked in: [    2.328550] CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.12.0-rc5mm-unstable-arm64\u002B #12 [    2.328683] Hardware name: QEMU QEMU Virtual Machine, BIOS 2024.02-2 03/11/2024 [    2.328790] pstate: 61000009 (nZCv daif -PAN -UAO -TCO \u002BDIT -SSBS BTYPE=--) [    2.328911] pc : __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.328930] lr : __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.328942] sp : ffff800083d6fc50 [    2.328961] x29: ffff800083d6fc50 x28: f2ff0000c1674410 x27: ffff8000820b0598 [    2.329061] x26: 000000007fffffff x25: 0000000000000010 x24: 0000000000002000 [    2.329101] x23: ffff800083d6fce8 x22: ffff8000832222e8 x21: ffff800083222388 [    2.329118] x20: f2ff0000c1674410 x19: f5ff0000c16364c0 x18: ffff800083d80030 [    2.329135] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 [    2.329152] x14: 0000000000000000 x13: 0a73747369786520 x12: 79646165726c6120 [    2.329169] x11: 656820747563205b x10: 2d2d2d2d2d2d2d2d x9 : 0000000000000000 [    2.329194] x8 : 0000000000000000 x7 : 0000000000000000 x6 : 0000000000000000 [    2.329210] x5 : 0000000000000000 x4 : 0000000000000000 x3 : 0000000000000000 [    2.329226] x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000000 [    2.329291] Call trace: [    2.329407]  __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.329499]  kmem_buckets_create\u002B0xfc/0x320 [    2.329526]  init_user_buckets\u002B0x34/0x78 [    2.329540]  do_one_initcall\u002B0x64/0x3c8 [    2.329550]  kernel_init_freeable\u002B0x26c/0x578 [    2.329562]  kernel_init\u002B0x3c/0x258 [    2.329574]  ret_from_fork\u002B0x10/0x20 [    2.329698] ---[ end trace 0000000000000000 ]---  [    2.403704] ------------[ cut here ]------------ [    2.404716] kmem_cache of name \u0027msg_msg-16\u0027 already exists [    2.404801] WARNING: CPU: 2 PID: 1 at mm/slab_common.c:107 __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.404842] Modules linked in: [    2.404971] CPU: 2 UID: 0 PID: 1 Comm: swapper/0 Tainted: G        W          6.12.0-rc5mm-unstable-arm64\u002B #12 [    2.405026] Tainted: [W]=WARN [    2.405043] Hardware name: QEMU QEMU Virtual Machine, BIOS 2024.02-2 03/11/2024 [    2.405057] pstate: 60400009 (nZCv daif \u002BPAN -UAO -TCO -DIT -SSBS BTYPE=--) [    2.405079] pc : __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.405100] lr : __kmem_cache_create_args\u002B0xb8/0x3b0 [    2.405111] sp : ffff800083d6fc50 [    2.405115] x29: ffff800083d6fc50 x28: fbff0000c1674410 x27: ffff8000820b0598 [    2.405135] x26: 000000000000ffd0 x25: 0000000000000010 x24: 0000000000006000 [    2.405153] x23: ffff800083d6fce8 x22: ffff8000832222e8 x21: ffff800083222388 [    2.405169] x20: fbff0000c1674410 x19: fdff0000c163d6c0 x18: ffff800083d80030 [    2.405185] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 [    2.405201] x14: 0000000000000000 x13: 0a73747369786520 x12: 79646165726c6120 [    2.405217] x11: 656820747563205b x10: 2d2d2d2d2d2d2d2d x9 : 0000000000000000 [    2.405233] x8 : 0000000000000000 x7 : 0000000000000000 x6 : 0000000000000000 [    2.405248] x5 : 0000000000000000 x4 : 0000000000000000 x3 : 0000000000000000 [    2.405271] x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000000 [    2.405287] Call trace: [    2 ---truncated---",
