The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1788168285 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: tracing/histogram: Fix a potential     memory leak for kstrdup() kfree() is missing on an error path to free the memory allocated by kstrdup(): p     = param = kstrdup(data->params[i], GFP_KERNEL); So it is better to free it via kfree(p). (CVE-2022-48768)

  - In the Linux kernel, the following vulnerability has been resolved: can: af_can: fix NULL pointer     dereference in can_rx_register() It causes NULL pointer dereference when testing as following: (a) use     syscall(__NR_socket, 0x10ul, 3ul, 0) to create netlink socket. (b) use syscall(__NR_sendmsg, ...) to     create bond link device and vxcan link device, and bind vxcan device to bond device (can also use     ifenslave command to bind vxcan device to bond device). (c) use syscall(__NR_socket, 0x1dul, 3ul, 1) to     create CAN socket. (d) use syscall(__NR_bind, ...) to bind the bond device to CAN socket. The bond device     invokes the can-raw protocol registration interface to receive CAN packets. However, ml_priv is not     allocated to the dev, dev_rcv_lists is assigned to NULL in can_rx_register(). In this case, it will occur     the NULL pointer dereference issue. The following is the stack information: BUG: kernel NULL pointer     dereference, address: 0000000000000008 PGD 122a4067 P4D 122a4067 PUD 1223c067 PMD 0 Oops: 0000 [#1]     PREEMPT SMP RIP: 0010:can_rx_register+0x12d/0x1e0 Call Trace: <TASK> raw_enable_filters+0x8d/0x120     raw_enable_allfilters+0x3b/0x130 raw_bind+0x118/0x4f0 __sys_bind+0x163/0x1a0 __x64_sys_bind+0x1e/0x30     do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x63/0xcd </TASK> (CVE-2022-49863)

  - In the Linux kernel, the following vulnerability has been resolved: net/tipc: fix slab-use-after-free Read     in tipc_aead_encrypt_done Syzbot reported a slab-use-after-free with the following call trace:

Thus, the     cryptd_queue_worker is triggered, and the tipc_crypto tx will be visited. tipc_disc_timeout     tipc_bearer_xmit_skb tipc_crypto_xmit tipc_aead_encrypt crypto_aead_encrypt // encrypt() simd_aead_encrypt     // crypto_simd_usable() is false child = &ctx->cryptd_tfm->base; simd_aead_encrypt crypto_aead_encrypt //     encrypt() cryptd_aead_encrypt_enqueue cryptd_aead_enqueue cryptd_enqueue_request // trigger     cryptd_queue_worker queue_work_on(smp_processor_id(), cryptd_wq, &cpu_queue->work) Fix this by holding net     reference count before encrypt. (CVE-2025-38052)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: eir: Fix possible crashes     on eir_create_adv_data eir_create_adv_data may attempt to add EIR_FLAGS and EIR_TX_POWER without checking     if that would fit. (CVE-2025-38303)

  - In the Linux kernel, the following vulnerability has been resolved: gve: prevent ethtool ops after     shutdown A crash can occur if an ethtool operation is invoked after shutdown() is called. shutdown() is     invoked during system shutdown to stop DMA operations without performing expensive deallocations. It is     discouraged to unregister the netdev in this path, so the device may still be visible to userspace and     kernel helpers. In gve, shutdown() tears down most internal data structures. If an ethtool operation is     dispatched after shutdown(), it will dereference freed or NULL pointers, leading to a kernel panic. While     graceful shutdown normally quiesces userspace before invoking the reboot syscall, forced shutdowns (as     observed on GCP VMs) can still trigger this path. Fix by calling netif_device_detach() in shutdown(). This     marks the device as detached so the ethtool ioctl handler will skip dispatching operations to the driver.
    (CVE-2025-38735)

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.

  - drop_monitor: fix size calculations for 64-bit attributes net_dm_packet_report_fill() and     net_dm_hw_packet_report_fill() use nla_put_u64_64bit() to append 64-bit attributes (NET_DM_ATTR_PC and     NET_DM_ATTR_TIMESTAMP). On 32-bit architectures without CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS,     nla_put_u64_64bit() may append a 4-byte NET_DM_ATTR_PAD attribute for 64-bit alignment. However,     net_dm_packet_report_size() and net_dm_hw_packet_report_size() used nla_total_size(sizeof(u64)) instead of     nla_total_size_64bit(sizeof(u64)), budgeting 12 bytes instead of up to 16 bytes. This under-estimation of     SKB size can lead to an skb_over_panic() when __nla_reserve() or skb_put() is subsequently called. Fix     this by using nla_total_size_64bit(sizeof(u64)) in both size calculations. (CVE-2026-68287)

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