If another CPU is \nconcurrently walking the xarray (e.g. via vm_unmap_aliases()), then it \nmay perform an out-of-bounds access to the remote queue thanks to an \nuninitialised index. \n \nThis has been observed as UBSAN errors in Android: \n \n | Internal error: UBSAN: array index out of bounds: 00000000f2005512 [#1] PREEMPT SMP \n | \n | Call trace: \n | purge_fragmented_block+0x204/0x21c \n | _vm_unmap_aliases+0x170/0x378 \n | vm_unmap_aliases+0x1c/0x28 \n | change_memory_common+0x1dc/0x26c \n | set_memory_ro+0x18/0x24 \n | module_enable_ro+0x98/0x238 \n | do_init_module+0x1b0/0x310 \n \nMove the initialisation of 'vb->cpu' in new_vmap_block() ahead of the \naddition to the xarray. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"27 Sep 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-09-27T15:53:37.000000Z"} 2024-09-27T15:53:37+00:00
