The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-604.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: idpf: fix adapter NULL pointer     dereference on reboot With SRIOV enabled, idpf ends up calling into idpf_remove() twice. First via     idpf_shutdown() and then again when idpf_remove() calls into sriov_disable(), because the VF devices use     the idpf driver, hence the same remove routine. When that happens, it is possible for the adapter to be     NULL from the first call to idpf_remove(), leading to a NULL pointer dereference. echo 1 >     /sys/class/net/<netif>/device/sriov_numvfs reboot BUG: kernel NULL pointer dereference, address:
    0000000000000020 ... RIP: 0010:idpf_remove+0x22/0x1f0 [idpf] ... ? idpf_remove+0x22/0x1f0 [idpf] ?     idpf_remove+0x1e4/0x1f0 [idpf] pci_device_remove+0x3f/0xb0 device_release_driver_internal+0x19f/0x200     pci_stop_bus_device+0x6d/0x90 pci_stop_and_remove_bus_device+0x12/0x20 pci_iov_remove_virtfn+0xbe/0x120     sriov_disable+0x34/0xe0 idpf_sriov_configure+0x58/0x140 [idpf] idpf_remove+0x1b9/0x1f0 [idpf]     idpf_shutdown+0x12/0x30 [idpf] pci_device_shutdown+0x35/0x60 device_shutdown+0x156/0x200 ... Replace the     direct idpf_remove() call in idpf_shutdown() with idpf_vc_core_deinit() and idpf_deinit_dflt_mbx(), which     perform the bulk of the cleanup, such as stopping the init task, freeing IRQs, destroying the vports and     freeing the mailbox. This avoids the calls to sriov_disable() in addition to a small netdev cleanup, and     destroying workqueues, which don't seem to be required on shutdown. (CVE-2025-22065)

  - In the Linux kernel, the following vulnerability has been resolved: idpf: convert workqueues to unbound     When a workqueue is created with `WQ_UNBOUND`, its work items are served by special worker-pools, whose     host workers are not bound to any specific CPU. In the default configuration (i.e. when     `queue_delayed_work` and friends do not specify which CPU to run the work item on), `WQ_UNBOUND` allows     the work item to be executed on any CPU in the same node of the CPU it was enqueued on. While this     solution potentially sacrifices locality, it avoids contention with other processes that might dominate     the CPU time of the processor the work item was scheduled on. This is not just a theoretical problem: in a     particular scenario misconfigured process was hogging most of the time from CPU0, leaving less than 0.5%     of its CPU time to the kworker. The IDPF workqueues that were using the kworker on CPU0 suffered large     completion delays as a result, causing performance degradation, timeouts and eventual system crash. * I     have also run a manual test to gauge the performance improvement. The test consists of an antagonist     process (`./stress --cpu 2`) consuming as much of CPU 0 as possible. This process is run under `taskset     01` to bind it to CPU0, and its priority is changed with `chrt -pQ 9900 10000 ${pid}` and `renice -n -20     ${pid}` after start. Then, the IDPF driver is forced to prefer CPU0 by editing all calls to     `queue_delayed_work`, `mod_delayed_work`, etc... to use CPU 0. Finally, `ktraces` for the workqueue events     are collected. Without the current patch, the antagonist process can force arbitrary delays between     `workqueue_queue_work` and `workqueue_execute_start`, that in my tests were as high as `30ms`. With the     current patch applied, the workqueue can be migrated to another unloaded CPU in the same node, and,     keeping everything else equal, the maximum delay I could see was `6us`. (CVE-2024-58057)

  - In the Linux kernel, the following vulnerability has been resolved: idpf: fix checksums set in     idpf_rx_rsc() idpf_rx_rsc() uses skb_transport_offset(skb) while the transport header is not set yet. This     triggers the following warning for CONFIG_DEBUG_NET=y builds.

  - In the Linux kernel, the following vulnerability has been resolved: idpf: fix null-ptr-deref in     idpf_features_check idpf_features_check is used to validate the TX packet. skb header length is compared     with the hardware supported value received from the device control plane. The value is stored in the     adapter structure and to access it, vport pointer is used. During reset all the vports are released and     the vport pointer that the netdev private structure points to is NULL. To avoid null-ptr-deref, store the     max header length value in netdev private structure. This also helps to cache the value and avoid     accessing adapter pointer in hot path.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.1.147-1.

    We recommend that you upgrade your linux packages.
