"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0070 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2023-4132:
    A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs
    during device initialization when the siano device is plugged in. This flaw allows a local user to crash
    the system, causing a denial of service condition.

    CVE-2023-45863:
    An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker
    can trigger a race condition that results in a fill_kobj_path out-of-bounds write.

    CVE-2023-35828:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in
    renesas_usb3_remove in drivers/usb/gadget/udc/renesas_usb3.c.

    CVE-2023-35824:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in
    drivers/media/pci/dm1105/dm1105.c.

    CVE-2023-35823:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in
    drivers/media/pci/saa7134/saa7134-core.c.

    CVE-2023-52973:
    In the Linux kernel, the following vulnerability has been resolved:

    vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF

    After a call to console_unlock() in vcs_read() the vc_data struct can be
    freed by vc_deallocate(). Because of that, the struct vc_data pointer
    load must be done at the top of while loop in vcs_read() to avoid a UAF
    when vcs_size() is called.

    Syzkaller reported a UAF in vcs_size().
