The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0437 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-46732:
    In the Linux kernel, the following vulnerability has been resolved:

    drm/amd/display: Assign linear_pitch_alignment even for VM

    [Description]     Assign linear_pitch_alignment so we don't cause a divide by 0     error in VM environments

    CVE-2024-46730:
    In the Linux kernel, the following vulnerability has been resolved:

    drm/amd/display: Ensure array index tg_inst won't be -1

    [WHY & HOW]     tg_inst will be a negative if timing_generator_count equals 0, which     should be checked before used.

    This fixes 2 OVERRUN issues reported by Coverity.

    CVE-2024-24861:
    A race condition was found in the Linux kernel's media/xc4000 device driver in xc4000     xc4000_get_frequency() function. This can result in return value overflow issue, possibly leading to     malfunction or denial of service issue.






    CVE-2024-38559:
    In the Linux kernel, the following vulnerability has been resolved:

    scsi: qedf: Ensure the copied buf is NUL terminated

    Currently, we allocate a count-sized kernel buffer and copy count from     userspace to that buffer. Later, we use kstrtouint on this buffer but we     don't ensure that the string is terminated inside the buffer, this can     lead to OOB read when using kstrtouint. Fix this issue by using     memdup_user_nul instead of memdup_user.

    CVE-2024-26937:
    In the Linux kernel, the following vulnerability has been resolved:

    drm/i915/gt: Reset queue_priority_hint on parking

    Originally, with strict in order execution, we could complete execution     only when the queue was empty. Preempt-to-busy allows replacement of an     active request that may complete before the preemption is processed by     HW. If that happens, the request is retired from the queue, but the     queue_priority_hint remains set, preventing direct submission until     after the next CS interrupt is processed.

    This preempt-to-busy race can be triggered by the heartbeat, which will     also act as the power-management barrier and upon completion allow us to     idle the HW. We may process the completion of the heartbeat, and begin     parking the engine before the CS event that restores the     queue_priority_hint, causing us to fail the assertion that it is MIN.

    CVE-2024-26935:
    In the Linux kernel, the following vulnerability has been resolved:

    scsi: core: Fix unremoved procfs host directory regression

    Commit fc663711b944 (scsi: core: Remove the /proc/scsi/${proc_name}     directory earlier) fixed a bug related to modules loading/unloading, by     adding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led     to a potential duplicate call to the hostdir_rm() routine, since it's also     called from scsi_host_dev_release(). That triggered a regression report,     which was then fixed by commit be03df3d4bfe (scsi: core: Fix a procfs host     directory removal regression). The fix just dropped the hostdir_rm() call     from dev_release().

    But it happens that this proc directory is created on scsi_host_alloc(),     and that function pairs with scsi_host_dev_release(), while     scsi_remove_host() pairs with scsi_add_host(). In other words, it seems the     reason for removing the proc directory on dev_release() was meant to cover     cases in which a SCSI host structure was allocated, but the call to     scsi_add_host() didn't happen. And that pattern happens to exist in some     error paths, for example.

    Syzkaller causes that by using USB raw gadget device, error'ing on     usb-storage driver, at usb_stor_probe2(). By checking that path, we can see     that the BadDevice label leads to a scsi_host_put() after a SCSI host     allocation, but there's no call to scsi_add_host() in such path. That leads     to messages like this in dmesg (and a leak of the SCSI host proc     structure):

    usb-storage 4-1:87.51: USB Mass Storage device detected     proc_dir_entry 'scsi/usb-storage' already registered     WARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376

    The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),     but guard that with the state check for SHOST_CREATED; there is even a     comment in scsi_host_dev_release() detailing that: such conditional is     meant for cases where the SCSI host was allocated but there was no calls to     {add,remove}_host(), like the usb-storage case.

    This is what we propose here and with that, the error path of usb-storage     does not trigger the warning anymore.

    CVE-2024-26934:
    In the Linux kernel, the following vulnerability has been resolved:

    USB: core: Fix deadlock in usb_deauthorize_interface()

    Among the attribute file callback routines in     drivers/usb/core/sysfs.c, the interface_authorized_store() function is     the only one which acquires a device lock on an ancestor device: It     calls usb_deauthorize_interface(), which locks the interface's parent     USB device.

    The will lead to deadlock if another process already owns that lock     and tries to remove the interface, whether through a configuration     change or because the device has been disconnected.  As part of the     removal procedure, device_del() waits for all ongoing sysfs attribute     callbacks to complete.  But usb_deauthorize_interface() can't complete     until the device lock has been released, and the lock won't be     released until the removal has finished.

    The mechanism provided by sysfs to prevent this kind of deadlock is     to use the sysfs_break_active_protection() function, which tells sysfs     not to wait for the attribute callback.

    The system was under memory stress where driver was not able to allocate an     SRB to carry out error recovery of cable pull.  The failure to flush causes     upper layer to start modifying scsi_cmnd.  When the system frees up some     memory, the subsequent cable pull trigger another command flush. At this     point the driver access a null pointer when attempting to DMA unmap the     SGL.

    Add a check to make sure commands are flush back on session tear down to     prevent the null pointer access.

    Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior.

    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).
