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:

    This fix has been tested with a syzkaller reproducer.

    CVE-2021-4083:
    A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4.

    CVE-2021-3739:
    A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the     Linux Kernel, where triggering the bug requires CAP_SYS_ADMIN. This flaw allows a local attacker to     crash the system or leak kernel internal information. The highest threat from this vulnerability is to     system availability.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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

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-2024:1026 advisory.

    Package updates are available for TencentOS Server 3 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:

    jfs: fix array-index-out-of-bounds in diNewExt

    [Analysis]     When the agstart is too large, it can cause agno overflow.

    [Fix]     After obtaining agno, if the value is invalid, exit the subsequent process.


    Modified the test from agno > MAXAG to agno >= MAXAG based on linux-next     report by kernel test robot (Dan Carpenter).

    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:
    In the Linux kernel 6.0.8, there is an out-of-bounds read in ntfs_attr_find in fs/ntfs/attrib.c.

    CVE-2023-1611:
    A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This     flaw allows an attacker to crash the system and possibly cause a kernel information lea

    CVE-2022-45919:
    An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a     use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.

    CVE-2022-45886:
    An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free.

    CVE-2022-42329:
    Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
    the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced     another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the     XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock     could occur in case of netpoll being active for the interface the xen-netback driver is connected to     (CVE-2022-42329).

    CVE-2022-3606:
    A vulnerability was found in Linux Kernel. It has been classified as problematic. This affects the     function find_prog_by_sec_insn of the file tools/lib/bpf/libbpf.c of the component BPF. The manipulation     leads to null pointer dereference. It is recommended to apply a patch to fix this issue. The identifier     VDB-211749 was assigned to this vulnerability.

    CVE-2022-20423:
    In rndis_set_response of rndis.c, there is a possible out of bounds write due to an integer overflow. This     could lead to local escalation of privilege if a malicious USB device is attached with no additional     execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions:

    CVE-2022-0480:
    A flaw was found in the filelock_init in fs/locks.c function in the Linux kernel. This issue can lead to     host memory exhaustion due to memcg not limiting the number of Portable Operating System Interface (POSIX)     file locks.

    CVE-2021-46972:
    In the Linux kernel, the following vulnerability has been resolved:

    ovl: fix leaked dentry

    Since commit 6815f479ca90 (ovl: use only uppermetacopy state in     ovl_lookup()), overlayfs doesn't put temporary dentry when there is a     metacopy error, which leads to dentry leaks when shutting down the related     superblock:
