  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbinder: fix UAF of alloc-\u003evma in race with munmap()\n\nIn commit 720c24192404 (\"ANDROID: binder: change down_write to\ndown_read\") binder assumed the mmap read lock is sufficient to protect\nalloc-\u003evma inside binder_update_page_range(). This used to be accurate\nuntil commit dd2283f2605e (\"mm: mmap: zap pages with read mmap_sem in\nmunmap\"), which now downgrades the mmap_lock after detaching the vma\nfrom the rbtree in munmap(). Then it proceeds to teardown and free the\nvma with only the read lock held.\n\nThis means that accesses to alloc-\u003evma in binder_update_page_range() now\nwill race with vm_area_free() in munmap() and can cause a UAF as shown\nin the following KASAN trace:\n\n  ==================================================================\n  BUG: KASAN: use-after-free in vm_insert_page+0x7c/0x1f0\n  Read of size 8 at addr ffff16204ad00600 by task server/558\n\n  CPU: 3 PID: 558 Comm: server Not tainted 5.10.150-00001-gdc8dcf942daa #1\n  Hardware name: linux,dummy-virt (DT)\n  Call trace:\n   dump_backtrace+0x0/0x2a0\n   show_stack+0x18/0x2c\n   dump_stack+0xf8/0x164\n   print_address_description.constprop.0+0x9c/0x538\n   kasan_report+0x120/0x200\n   __asan_load8+0xa0/0xc4\n   vm_insert_page+0x7c/0x1f0\n   binder_update_page_range+0x278/0x50c\n   binder_alloc_new_buf+0x3f0/0xba0\n   binder_transaction+0x64c/0x3040\n   binder_thread_write+0x924/0x2020\n   binder_ioctl+0x1610/0x2e5c\n   __arm64_sys_ioctl+0xd4/0x120\n   el0_svc_common.constprop.0+0xac/0x270\n   do_el0_svc+0x38/0xa0\n   el0_svc+0x1c/0x2c\n   el0_sync_handler+0xe8/0x114\n   el0_sync+0x180/0x1c0\n\n  Allocated by task 559:\n   kasan_save_stack+0x38/0x6c\n   __kasan_kmalloc.constprop.0+0xe4/0xf0\n   kasan_slab_alloc+0x18/0x2c\n   kmem_cache_alloc+0x1b0/0x2d0\n   vm_area_alloc+0x28/0x94\n   mmap_region+0x378/0x920\n   do_mmap+0x3f0/0x600\n   vm_mmap_pgoff+0x150/0x17c\n   ksys_mmap_pgoff+0x284/0x2dc\n   __arm64_sys_mmap+0x84/0xa4\n   el0_svc_common.constprop.0+0xac/0x270\n   do_el0_svc+0x38/0xa0\n   el0_svc+0x1c/0x2c\n   el0_sync_handler+0xe8/0x114\n   el0_sync+0x180/0x1c0\n\n  Freed by task 560:\n   kasan_save_stack+0x38/0x6c\n   kasan_set_track+0x28/0x40\n   kasan_set_free_info+0x24/0x4c\n   __kasan_slab_free+0x100/0x164\n   kasan_slab_free+0x14/0x20\n   kmem_cache_free+0xc4/0x34c\n   vm_area_free+0x1c/0x2c\n   remove_vma+0x7c/0x94\n   __do_munmap+0x358/0x710\n   __vm_munmap+0xbc/0x130\n   __arm64_sys_munmap+0x4c/0x64\n   el0_svc_common.constprop.0+0xac/0x270\n   do_el0_svc+0x38/0xa0\n   el0_svc+0x1c/0x2c\n   el0_sync_handler+0xe8/0x114\n   el0_sync+0x180/0x1c0\n\n  [...]\n  ==================================================================\n\nTo prevent the race above, revert back to taking the mmap write lock\ninside binder_update_page_range(). One might expect an increase of mmap\nlock contention. However, binder already serializes these calls via top\nlevel alloc-\u003emutex. Also, there was no performance impact shown when\nrunning the binder benchmark tests.\n\nNote this patch is specific to stable branches 5.4 and 5.10. Since in\nnewer kernel releases binder no longer caches a pointer to the vma.\nInstead, it has been refactored to use vma_lookup() which avoids the\nissue described here. This switch was introduced in commit a43cfc87caaf\n(\"android: binder: stop saving a pointer to the VMA\").",

  "details": "This vulnerability allows local attackers to escalate privileges on affected Tesla vehicles. An attacker must first obtain the ability to execute privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of the wowlan_config data structure. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-17543.",
