| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm: krealloc: Fix MTE false alarm in __do_krealloc\n\nThis patch addresses an issue introduced by commit 1a83a716ec233 (\"mm:\nkrealloc: consider spare memory for __GFP_ZERO\") which causes MTE\n(Memory Tagging Extension) to falsely report a slab-out-of-bounds error.\n\nThe problem occurs when zeroing out spare memory in __do_krealloc. The\noriginal code only considered software-based KASAN and did not account\nfor MTE. It does not reset the KASAN tag before calling memset, leading\nto a mismatch between the pointer tag and the memory tag, resulting\nin a false positive.\n\nExample of the error:\n==================================================================\nswapper/0: BUG: KASAN: slab-out-of-bounds in __memset+0x84/0x188\nswapper/0: Write at addr f4ffff8005f0fdf0 by task swapper/0/1\nswapper/0: Pointer tag: [f4], memory tag: [fe]\nswapper/0:\nswapper/0: CPU: 4 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.12.\nswapper/0: Hardware name: MT6991(ENG) (DT)\nswapper/0: Call trace:\nswapper/0: dump_backtrace+0xfc/0x17c\nswapper/0: show_stack+0x18/0x28\nswapper/0: dump_stack_lvl+0x40/0xa0\nswapper/0: print_report+0x1b8/0x71c\nswapper/0: kasan_report+0xec/0x14c\nswapper/0: __do_kernel_fault+0x60/0x29c\nswapper/0: do_bad_area+0x30/0xdc\nswapper/0: do_tag_check_fault+0x20/0x34\nswapper/0: do_mem_abort+0x58/0x104\nswapper/0: el1_abort+0x3c/0x5c\nswapper/0: el1h_64_sync_handler+0x80/0xcc\nswapper/0: el1h_64_sync+0x68/0x6c\nswapper/0: __memset+0x84/0x188\nswapper/0: btf_populate_kfunc_set+0x280/0x3d8\nswapper/0: __register_btf_kfunc_id_set+0x43c/0x468\nswapper/0: register_btf_kfunc_id_set+0x48/0x60\nswapper/0: register_nf_nat_bpf+0x1c/0x40\nswapper/0: nf_nat_init+0xc0/0x128\nswapper/0: do_one_initcall+0x184/0x464\nswapper/0: do_initcall_level+0xdc/0x1b0\nswapper/0: do_initcalls+0x70/0xc0\nswapper/0: do_basic_setup+0x1c/0x28\nswapper/0: kernel_init_freeable+0x144/0x1b8\nswapper/0: kernel_init+0x20/0x1a8\nswapper/0: ret_from_fork+0x10/0x20\n==================================================================" |
