"The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1763031616 advisory.

  - BlueZ Audio Profile AVRCP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This
    vulnerability allows network-adjacent attackers to execute arbitrary code via Bluetooth on affected
    installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must
    connect to a malicious device. The specific flaw exists within the handling of the AVRCP protocol. The
    issue results from the lack of proper validation of the length of user-supplied data prior to copying it
    to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the
    context of root. Was ZDI-CAN-19909. (CVE-2023-44431)

  - Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and
    establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of
    HID messages when no user interaction has occurred in the Central role to authorize such access. An
    example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556
    mitigation would have already addressed this Bluetooth HID Hosts issue. (CVE-2023-45866)

  - BlueZ Audio Profile AVRCP avrcp_parse_attribute_list Out-Of-Bounds Read Information Disclosure
    Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information via
    Bluetooth on affected installations of BlueZ. User interaction is required to exploit this vulnerability
    in that the target must connect to a malicious device. The specific flaw exists within the handling of the
    AVRCP protocol. The issue results from the lack of proper validation of user-supplied data, which can
    result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with
    other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20852.
    (CVE-2023-51580)

  - BlueZ Audio Profile AVRCP parse_media_element Out-Of-Bounds Read Information Disclosure Vulnerability.
    This vulnerability allows network-adjacent attackers to disclose sensitive information via Bluetooth on
    affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the
    target must connect to a malicious device. The specific flaw exists within the handling of the AVRCP
    protocol. The issue results from the lack of proper validation of user-supplied data, which can result in
    a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other
    vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20853. (CVE-2023-51589)

  - BlueZ Audio Profile AVRCP parse_media_folder Out-Of-Bounds Read Information Disclosure Vulnerability. This
    vulnerability allows network-adjacent attackers to disclose sensitive information via Bluetooth on
    affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the
    target must connect to a malicious device. The specific flaw exists within the handling of the AVRCP
    protocol. The issue results from the lack of proper validation of user-supplied data, which can result in
    a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other
    vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20854. (CVE-2023-51592)
