The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1031 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2024-1086:
    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence     the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error     which resembles NF_ACCEPT.

    We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

    CVE-2024-0565:
    An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service.

    CVE-2023-6931:
    A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation.

    A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in     perf_read_group().

    We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.



    CVE-2023-6610:
    An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.

    CVE-2023-6606:
    An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.

    CVE-2023-6121:
    An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw     allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data to be printed (and potentially leaked) to the kernel ring buffer (dmesg).

    CVE-2023-52600:
    In the Linux kernel, the following vulnerability has been resolved:

    jfs: fix uaf in jfs_evict_inode

    When the execution of diMount(ipimap) fails, the object ipimap that has been     released may be accessed in diFreeSpecial(). Asynchronous ipimap release occurs     when rcu_core() calls jfs_free_node().

    Therefore, when diMount(ipimap) fails, sbi->ipimap should not be initialized as     ipimap.

    CVE-2023-52599:
    In the Linux kernel, the following vulnerability has been resolved:

    CVE-2023-52591:
    In the Linux kernel, the following vulnerability has been resolved:

    reiserfs: Avoid touching renamed directory if parent does not change

    The VFS will not be locking moved directory if its parent does not     change. Change reiserfs rename code to avoid touching renamed directory     if its parent does not change as without locking that can corrupt the     filesystem.

    CVE-2023-52590:
    In the Linux kernel, the following vulnerability has been resolved:

    ocfs2: Avoid touching renamed directory if parent does not change

    The VFS will not be locking moved directory if its parent does not     change. Change ocfs2 rename code to avoid touching renamed directory if     its parent does not change as without locking that can corrupt the     filesystem.

    CVE-2023-52583:
    In the Linux kernel, the following vulnerability has been resolved:

    ceph: fix deadlock or deadcode of misusing dget()

    The lock order is incorrect between denty and its parent, we should     always make sure that the parent get the lock first.

    But since this deadcode is never used and the parent dir will always     be set from the callers, let's just remove it.

    CVE-2023-26607:
