"The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
TuxCare CENTOS7:CLSA-2026:1780133416 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: nvme-rdma: fix possible use-after-free
    in transport error_recovery work While nvme_rdma_submit_async_event_work is checking the ctrl and queue
    state before preparing the AER command and scheduling io_work, in order to fully prevent a race where this
    check is not reliable the error recovery work must flush async_event_work before continuing to destroy the
    admin queue after setting the ctrl state to RESETTING such that there is no race .submit_async_event and
    the error recovery handler itself changing the ctrl state. (CVE-2022-48788)

  - In the Linux kernel, the following vulnerability has been resolved: hwmon: (ibmpex) Fix possible UAF when
    ibmpex_register_bmc() fails Smatch report warning as follows: drivers/hwmon/ibmpex.c:509
    ibmpex_register_bmc() warn: '&data->list' not removed from list If ibmpex_find_sensors() fails in
    ibmpex_register_bmc(), data will be freed, but data->list will not be removed from driver_data.bmc_data,
    then list traversal may cause UAF. Fix by removeing it from driver_data.bmc_data before free().
    (CVE-2022-49029)

  - In the Linux kernel, the following vulnerability has been resolved: Input: powermate - fix use-after-free
    in powermate_config_complete syzbot has found a use-after-free bug [1] in the powermate driver. This
    happens when the device is disconnected, which leads to a memory free from the powermate_device struct.
    When an asynchronous control message completes after the kfree and its callback is invoked, the lock does
    not exist anymore and hence the bug. Use usb_kill_urb() on pm->config to cancel any in-progress requests
    upon device disconnection. [1] https://syzkaller.appspot.com/bug?extid=0434ac83f907a1dbdd1e
    (CVE-2023-52475)

  - In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/via: Avoid potential array
    out-of-bound in add_secret_dac_path() snd_hda_get_connections() can return a negative error code. It may
    lead to accessing 'conn' array at a negative index. Found by Linux Verification Center (linuxtesting.org)
    with SVACE. (CVE-2023-52988)
