"The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
TuxCare CENTOS7:CLSA-2025:1740649075 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out of bounds
    reads when finding clock sources The current USB-audio driver code doesn't check bLength of each
    descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a
    shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity
    checks to the validator functions for the clock descriptor traversal. When the descriptor length is
    shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we
    can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor
    of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to
    be checked in addition to the sizeof() check. (CVE-2024-53150)

  - In the Linux kernel, the following vulnerability has been resolved: drm/dp_mst: Ensure mst_primary pointer
    is valid in drm_dp_mst_handle_up_req() While receiving an MST up request message from one thread in
    drm_dp_mst_handle_up_req(), the MST topology could be removed from another thread via
    drm_dp_mst_topology_mgr_set_mst(false), freeing mst_primary and setting
    drm_dp_mst_topology_mgr::mst_primary to NULL. This could lead to a NULL deref/use-after-free of
    mst_primary in drm_dp_mst_handle_up_req(). Avoid the above by holding a reference for mst_primary in
    drm_dp_mst_handle_up_req() while it's used. v2: Fix kfreeing the request if getting an mst_primary
    reference fails. (CVE-2024-57798)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
