In the Linux kernel, the following vulnerability has been resolved: mm: fix unexpected zeroed page mapping with zram swap Two processes under CLONE_VM cloning, user process can be corrupted by seeing zeroed page unexpectedly. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage valid data swap_slot_free_notify delete zram entry swap_readpage zeroed(invalid) data pte_lock map the *zero data* to userspace pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return and next refault will read zeroed data The swap_slot_free_notify is bogus for CLONE_VM case since it doesn't increase the refcount of swap slot at copy_mm so it couldn't catch up whether it's safe or not to discard data from backing device. In the case, only the lock it could rely on to synchronize swap slot freeing is page table lock. Thus, this patch gets rid of the swap_slot_free_notify function. With this patch, CPU A will see correct data. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage original data pte_lock map the original data swap_free swap_range_free bd_disk->fops->swap_slot_free_notify swap_readpage read zeroed data pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return on next refault will see mapped data by CPU B The concern of the patch would increase memory consumption since it could keep wasted memory with compressed form in zram as well as uncompressed form in address space. However, most of cases of zram uses no readahead and do_swap_page is followed by swap_free so it will free the compressed form from in zram quickly.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: mm: fix unexpected zeroed page mapping     with zram swap Two processes under CLONE_VM cloning, user process can be corrupted by seeing zeroed page     unexpectedly.

The version of kernel installed on the remote host is prior to 5.10.112-108.499. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-036 advisory.

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

    ubi: Fix race condition between ctrl_cdev_ioctl and ubi_cdev_ioctl (CVE-2021-47634)

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

    Revert Revert block, bfq: honor already-setup queue merges (CVE-2021-47646)

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

    ASoC: soc-compress: prevent the potentially use of null pointer (CVE-2021-47650)

    A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in     the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user     function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
    (CVE-2022-0168)

    When the KVM updates the guest's page table entry, it will first use get_user_pages_fast() to pin the     page, and when it fails (e.g. the vma->flags has VM_IO or VM_PFNMAP), it will get corresponding VMA where     the page lies in through find_vma_intersection(), calculate the physical address, and map the page to the     kernel virtual address through memremap(), and finally, write the update.The problem is that when we get     the vma through find_vma_intersection(), only VM_PFNMAP is checked, not both VM_IO and VM_PFNMAP. In the     reproducer below, after the KVM_SET_USER_MEMORY_REGION is completed, we replace the guest's memory mapping     with the kernel-user shared region of io_uring and then perform the KVM_TRANSLATE operation, which finally     triggers the page table entry update. Now, memremap() will return page_offset_base (direct mapping of all     physical memory) + vaddr (the linear address of KVM_TRANSLATE) + vm_pgoff (the offset when io_uring     performs mmap(2)), and use the return value as the base address for CMPXCHG (write 0x21 in this case).
    Since both vaddr and vm_pgoff are controllable by the user-mode process, writing may exceed the previously     mapped guest memory space and trigger exceptions such as UAF. The vulnerability shares similarities with     CVE-2021-22543. (CVE-2022-1158)

    A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

    A use-after-free flaw was found in the Linux kernel's io_uring interface subsystem in the way a user     triggers a race condition between timeout flush and removal. This flaw allows a local user to crash or     escalate their privileges on the system. (CVE-2022-29582)

    A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

    A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information. (CVE-2022-41858)

The version of kernel installed on the remote host is prior to 5.4.196-108.356. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-026 advisory.

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

    dm: fix mempool NULL pointer race when completing IO (CVE-2021-47435)

    A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in     the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or     CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)

    A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

    perf: Fix sys_perf_event_open() race against self (CVE-2022-1729)

    floppy: disable FDRAWCMD by default (CVE-2022-1836)

    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

    The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state. (CVE-2022-28893)

    Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

    An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap. (CVE-2022-48619)

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

    mm: fix unexpected zeroed page mapping with zram swap (CVE-2022-49052)

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

    ALSA: pcm: Fix races among concurrent hw_params and hw_free calls (CVE-2022-49291)

    A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network     subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the     system, and could even lead to a kernel information leak problem. (CVE-2023-1838)

    A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem. (CVE-2023-4387)

    A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during cleanup.
    (CVE-2023-4459)
