"The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
TuxCare CENTOS7:CLSA-2024:1720468480 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: i2c: Fix a potential use after free
    Free the adap structure only after we are done using it. This patch just moves the put_device() down a bit
    to avoid the use after free. [wsa: added comment to the code, added Fixes tag] (CVE-2019-25162)

  - An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer
    overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community
    argue that the integer overflow does not lead to a security issue in this case. (CVE-2020-13974)

  - Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification 1.0B through 5.2 may permit an
    unauthenticated nearby device to spoof the BD_ADDR of the peer device to complete pairing without
    knowledge of the PIN. (CVE-2020-26555)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could
    happen if removing device (that is not common to remove video card physically without power-off, but same
    happens if unbind the driver). (CVE-2020-27820)

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information
    disclosure via adjacent access. (CVE-2021-0129)

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