    The reproducer was trying to read /proc/$PID/smaps when calling     MADV_FREE at the mean time.  MADV_FREE may split THPs if it is called     for partial THP.  It may trigger the below race:

               CPU A                         CPU B

    When calling PageDoubleMap() this page is not a tail page of THP anymore     so the BUG is triggered.

    This could be fixed by elevated refcount of the page before calling     mapcount, but that would prevent it from counting migration entries, and     it seems overkilling because the race just could happen when PMD is     split so all PTE entries of tail pages are actually migration entries,     and smaps_account() does treat migration entries as mapcount == 1 as     Kirill pointed out.

    Add a new parameter for smaps_account() to tell this entry is migration     entry then skip calling page_mapcount().  Don't skip getting mapcount     for device private entries since they do track references with mapcount.

    Pagemap also has the similar issue although it was not reported.  Fixed     it as well.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989182 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    fs/proc: task_mmu.c: don't read mapcount for migration entry

    The syzbot reported the below BUG:

    The reproducer was trying to read /proc/$PID/smaps when calling     MADV_FREE at the mean time.  MADV_FREE may split THPs if it is called     for partial THP.  It may trigger the below race:

               CPU A                         CPU B
               -----                         -----       smaps walk:                      MADV_FREE:
      page_mapcount()         PageCompound()                                        split_huge_page()         page = compound_head(page)         PageDoubleMap(page)

    When calling PageDoubleMap() this page is not a tail page of THP anymore     so the BUG is triggered.

    This could be fixed by elevated refcount of the page before calling     mapcount, but that would prevent it from counting migration entries, and     it seems overkilling because the race just could happen when PMD is     split so all PTE entries of tail pages are actually migration entries,     and smaps_account() does treat migration entries as mapcount == 1 as     Kirill pointed out.

    Add a new parameter for smaps_account() to tell this entry is migration     entry then skip calling page_mapcount().  Don't skip getting mapcount     for device private entries since they do track references with mapcount.

    Pagemap also has the similar issue although it was not reported.  Fixed     it as well.

The version of kernel installed on the remote host is prior to 5.10.102-99.473. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-011 advisory.

    AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The     Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on     AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26341)

This is done by default, and no administrator action is needed. (CVE-2021-26401)

    An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

    In the Linux kernel, the following vulnerability has been resolved:

    PCI: pciehp: Fix infinite loop in IRQ handler upon power fault (CVE-2021-47617)

    Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure. (CVE-2022-0001)

    Non-transparent sharing of branch predictor within a context in some Intel(r) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

    A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

    A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

    A use-after-free vulnerability was found in the tc_new_tfilter function in net/sched/cls_api.c in the     Linux kernel. The availability of local, unprivileged user namespaces allows privilege escalation.
    (CVE-2022-1055)

    The Amazon Linux kernel now enables, by default, a software mitigation for this issue, on all ARM-based     EC2 instance types. (CVE-2022-23960)

    A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet     Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
