In the Linux kernel, the following vulnerability has been resolved: net: ena: fix MMIO read buffer leak on probe failure ena_device_init() initializes the MMIO read mechanism with ena_com_mmio_reg_read_request_init(), which allocates a coherent DMA buffer for MMIO read responses. The normal removal path releases this buffer through ena_com_mmio_reg_read_request_destroy(). However, if ena_probe() fails after ena_device_init() succeeds, the error path destroys the admin resources and eventually frees ena_dev without destroying the MMIO read request, leaving the coherent DMA buffer allocated. Call ena_com_mmio_reg_read_request_destroy() in the probe error path before releasing the remaining device resources. This issue was found by manual code inspection.

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1792976962 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: avoid uninit memory read     in ath9k_htc_rx_msg() syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for     ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with pkt_len = 0 but     ath9k_hif_usb_rx_stream() uses __dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that     pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb with uninitialized memory and     ath9k_htc_rx_msg() is reading from uninitialized memory. Since bytes accessed by ath9k_htc_rx_msg() is not     known until ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid pkt_len at if     (pkt_len > 2 * MAX_RX_BUF_SIZE) { line in ath9k_hif_usb_rx_stream(). We have two choices. One is to     workaround by adding __GFP_ZERO so that ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to     let ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose the latter. Note that I'm not     sure threshold condition is correct, for I can't find details on possible packet length used by this     protocol. (CVE-2022-50709)

  - In the Linux kernel, the following vulnerability has been resolved: configfs: fix possible memory leak in     configfs_create_dir() kmemleak reported memory leaks in configfs_create_dir(): unreferenced object     0xffff888009f6af00 (size 192): comm modprobe, pid 3777, jiffies 4295537735 (age 233.784s) backtrace:

This is     because the refcount is not correct in configfs_make_dirent(). For normal stage, the refcount is changing     as: configfs_register_subsystem() configfs_create_dir() configfs_make_dirent() configfs_new_dirent() # set     s_count = 1 dentry->d_fsdata = configfs_get(sd); # s_count = 2 ... configfs_unregister_subsystem()     configfs_remove_dir() remove_dir() configfs_remove_dirent() # s_count = 1 dput() ...
    *dentry_unlink_inode()* configfs_d_iput() # s_count = 0, release However, if we failed in     configfs_create(): configfs_register_subsystem() configfs_create_dir() configfs_make_dirent() # s_count =     2 ... configfs_create() # fail ->out_remove: configfs_remove_dirent(dentry) configfs_put(sd) # s_count = 1     return PTR_ERR(inode); There is no inode in the error path, so the configfs_d_iput() is lost and makes sd     and fragment memory leaked. To fix this, when we failed in configfs_create(), manually call     configfs_put(sd) to keep the refcount correct. (CVE-2022-50751)

    __memcpy+0x110/0x260 read_kcore+0x584/0x778 proc_reg_read+0xb4/0xe4 During early boot, memblock reserves     the pages for the ramoops reserved memory node in DT that would otherwise be part of the direct lowmem     mapping. Pstore's ram backend reuses those reserved pages to change the memory type (writeback or non-     cached) by passing the pages to vmap() (see pfn_to_page() usage in persistent_ram_vmap() for more details)     with specific flags. When read_kcore() starts iterating over the vmalloc region, it runs over the virtual     address that vmap() returned for ramoops. In aligned_vread() the virtual address is passed to     vmalloc_to_page() which returns the page struct for the reserved lowmem area. That lowmem page is passed     to kmap_atomic(), which effectively calls page_to_virt() that assumes a lowmem page struct must be     directly accessible with __va() and friends. These pages are mapped via vmap() though, and the lowmem     mapping was never made, so accessing them via the lowmem virtual address oopses like above. Let's side-     step this problem by passing VM_IOREMAP to vmap(). This will tell vread() to not include the ramoops     region in the kcore. Instead the area will look like a bunch of zeros. The alternative is to teach kmap()     about vmalloc areas that intersect with lowmem. Presumably such a change isn't a one-liner, and there     isn't much interest in inspecting the ramoops region in kcore files anyway, so the most expedient route is     taken for now. (CVE-2022-50849)

  - In the Linux kernel, the following vulnerability has been resolved: hwrng: amd - Fix PCI device refcount     leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it     will increase the reference count for the returned pci_dev and also decrease the reference count for the     input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to     call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the normal and error     path. (CVE-2022-50868)

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/srp: Do not call scsi_done() from     srp_abort() After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler callback, it performs     one of the following actions: * Call scsi_queue_insert(). * Call scsi_finish_command(). * Call     scsi_eh_scmd_add(). Hence, SCSI abort handlers must not call scsi_done(). Otherwise all the above actions     would trigger a use-after-free. Hence remove the scsi_done() call from srp_abort(). Keep the     srp_free_req() call before returning SUCCESS because we may not see the command again if SUCCESS is     returned. (CVE-2023-52515)

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

    For Debian 12 bookworm, these problems have been fixed in version     6.12.113-1~deb12u1.  This update additionally includes many more bug     fixes from stable updates 6.12.112 and 6.12.113.

    We recommend that you upgrade your linux-6.12 packages.

    For the detailed security status of linux-6.12 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.12

    Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://wiki.debian.org/LTS     Attachment:

Tenable has extracted the preceding description block directly from the Debian 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - net: ena: fix MMIO read buffer leak on probe failure ena_device_init() initializes the MMIO read mechanism     with ena_com_mmio_reg_read_request_init(), which allocates a coherent DMA buffer for MMIO read responses.
    The normal removal path releases this buffer through ena_com_mmio_reg_read_request_destroy(). However, if     ena_probe() fails after ena_device_init() succeeds, the error path destroys the admin resources and     eventually frees ena_dev without destroying the MMIO read request, leaving the coherent DMA buffer     allocated. Call ena_com_mmio_reg_read_request_destroy() in the probe error path before releasing the     remaining device resources. This issue was found by manual code inspection. (CVE-2026-98486)

Note that Nessus relies on the presence of the package as reported by the vendor.
