{"id":"CVE-2026-98507","summary":"mm/rmap: fix missing barrier between anon_vma init and vma-\u003eanon_vma publish","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/rmap: fix missing barrier between anon_vma init and vma-\u003eanon_vma publish\n\nOn arm64 server, we find that a task trying to grab the anon_vma lock\ntriggers hungtask.\n\nINFO: task main:2354726 blocked for more than 120 seconds.\n      Tainted: G            E     5.10.0-0021.aarch64 #1\n\"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\ntask:main            state:D stack:    0 pid:2354726 ppid:2350673 flags:0x00000a01\nCall trace:\n __switch_to+0x7c/0xbc\n __schedule+0x3b4/0x8a0\n schedule+0x50/0xe0\n rwsem_down_write_slowpath+0x3cc/0x6cc\n down_write+0x60/0x260\n __anon_vma_prepare+0x6c/0x210\n do_anonymous_page+0x258/0x660\n handle_pte_fault+0x188/0x214\n __handle_mm_fault+0x1b0/0x380\n handle_mm_fault+0xf4/0x284\n do_page_fault+0x19c/0x494\n do_translation_fault+0xcc/0xf8\n do_mem_abort+0x48/0xac\n el0_da+0x44/0x80\n el0_sync_handler+0x88/0xb4\n el0_sync+0x160/0x180\n\nAfter analyzing the vmcore, we found the anon_vma-\u003eroot-\u003erwsem.count is\n-1.  There is another anon_vma whose anon_vma-\u003eroot-\u003erwsem.count is 1, the\nanon_vma-\u003eroot-\u003erwsem.owner shows the lock is held, but the stack of the\ntask shows the task doesn't hold the anon_vma lock.\n\nAfter adding more debugging info, we found __anon_vma_prepare() reuses\nanon_vma and triggers the UAF of anon_vma-\u003eroot due to missing memory\nbarrier, leading to locking and unlocking two different anon_vma-\u003eroot,\nthus leading to an anon_vma will never be unlocked, and another anon_vma\ncouldn't be locked anymore.\n\nThis race requires two adjacent VMAs that are not merged but are\nanon_vma-compatible (e.g., they differ in VMA_ACCESS_FLAGS that can be\nchanged by mprotect()).  Two threads fault on each VMA concurrently, both\ncalling __anon_vma_prepare() with only mmap_lock held for reading.\n\n    THREAD A                             THREAD B\n__anon_vma_prepare                __anon_vma_prepare\n find_mergeable_anon_vma() -\u003e NULL\n anon_vma = anon_vma_alloc();\n   anon_vma-\u003eroot = anon_vma;\n // the two stores may be reordered\n vma-\u003eanon_vma = anon_vma;\n                                   // finds A's anon_vma\n                                   anon_vma = find_mergeable_anon_vma(vma);\n                                   anon_vma_lock_write(anon_vma);\n                                     // may still see the old root\n                                     down_write(&anon_vma-\u003eroot-\u003erwsem);\n                                   anon_vma_unlock_write(anon_vma);\n                                     // see the new root, never unlock old\n                                     up_write(&anon_vma-\u003eroot-\u003erwsem);\n\nthread A triggers page fault and calls __anon_vma_prepare() to prepare\nanon_vma for the faulting vma.  __anon_vma_prepare() allocates and\ninitializes a new anon_vma, and then publishes it to the vma with a plain\nstore.  anon_vma_prepare() only requires the mmap_lock to be held for\nreading, so two threads can fault on adjacent VMAs at the same time. \nWhile thread A publishes a new anon_vma, thread B could find the anon_vma\nvia find_mergeable_anon_vma() and then locks anon_vma-\u003eroot-\u003erwsem.\n\nThe store to anon_vma-\u003eroot in anon_vma_alloc() and the store to\nvma-\u003eanon_vma can be reordered.  The anon_vma_lock_write() and spin_lock()\nonly provide acquire semantics, which do not prevent prior stores from\nbeing reordered after them.  The release semantics of the corresponding\nspin_unlock() and anon_vma_unlock_write() come too late, the store to\nvma-\u003eanon_vma is already published before they take effect.  As a result,\nthread B can observe the following order:\n\n    vma-\u003eanon_vma = anon_vma;\n    anon_vma-\u003eroot = anon_vma;\n\nThe anon_vma slab is SLAB_TYPESAFE_BY_RCU, so a newly allocated anon_vma\nmay reuse memory from a previously freed one.  The constructor\n(anon_vma_ctor) does not reset anon_vma-\u003eroot, and __put_anon_vma()\ndoesn't clear it either, so the old root value persists until\nanon_vma_alloc() overwrites it.  If that store isn't
