The CentOS Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS6:CLSA-2026:1791949745 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report     buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it     during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted     report. (CVE-2024-50302)

  - In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential out-of-     bound accesses for Extigy and Mbox devices A bogus device can provide a bNumConfigurations value that     exceeds the initial value used in usb_get_configuration for allocating dev->config. This can lead to out-     of-bounds accesses later, e.g. in usb_destroy_configuration. (CVE-2024-53197)

  - In the Linux kernel, the following vulnerability has been resolved: smb: client: reject userspace     cifs.spnego descriptions cifs.spnego key descriptions contain authority-bearing fields such as pid, uid,     creduid, and upcall_target that cifs.upcall treats as kernel-originating inputs. However, userspace can     also create keys of this type through request_key(2) or add_key(2), allowing those fields to be supplied     without CIFS origin. Only accept cifs.spnego descriptions while CIFS is using its private spnego_cred to     request the key. (CVE-2026-46243)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: serialize accept_q access     bt_sock_poll() walks the accept queue without synchronization, while child teardown can unlink the same     socket and drop its last reference. The unsynchronized accept queue walk has existed since the initial     Bluetooth import. Protect accept_q with a dedicated lock for queue updates and polling. Also rework     bt_accept_dequeue() to take temporary child references under the queue lock before dropping it and locking     the child socket. (CVE-2026-52918)

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: make ebt_snat ARP     rewrite writable The ebtables SNAT target keeps the Ethernet source address rewrite behind     skb_ensure_writable(skb, 0). This is intentional: at the bridge ebtables hooks the Ethernet header is     addressed through skb_mac_header()/eth_hdr(), while skb->data points at the Ethernet payload. Asking     skb_ensure_writable() for ETH_HLEN bytes would check the payload, not the Ethernet header, and would     reintroduce the small packet regression fixed by commit 63137bc5882a. However, the optional ARP sender     hardware address rewrite is different. It writes through skb_store_bits() at an offset relative to     skb->data: skb_store_bits(skb, sizeof(struct arphdr), info->mac, ETH_ALEN) skb_header_pointer() only     safely reads the ARP header; it does not make the later sender hardware address range writable. If that     range is still held in a nonlinear skb fragment backed by a splice-imported file page, skb_store_bits()     maps the frag page and copies the new MAC address directly into it. Ensure the ARP SHA range is writable     before reading the ARP header and before calling skb_store_bits(). (CVE-2026-53266)

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