In the Linux kernel, the following vulnerability has been resolved: xen-netfront: Add missing skb_mark_for_recycle Notice that skb_mark_for_recycle() is introduced later than fixes tag in commit 6a5bcd84e886 ("page_pool: Allow drivers to hint on SKB recycling"). It is believed that fixes tag were missing a call to page_pool_release_page() between v5.9 to v5.14, after which is should have used skb_mark_for_recycle(). Since v6.6 the call page_pool_release_page() were removed (in commit 535b9c61bdef ("net: page_pool: hide page_pool_release_page()") and remaining callers converted (in commit 6bfef2ec0172 ("Merge branch 'net-page_pool-remove-page_pool_release_page'")). This leak became visible in v6.8 via commit dba1b8a7ab68 ("mm/page_pool: catch page_pool memory leaks").

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:4106 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * kernel: netfilter: nf_tables: use timestamp to check for set element timeout (CVE-2024-27397)

    * kernel: xen-netfront: Add missing skb_mark_for_recycle (CVE-2024-27393)

    * kernel: netfilter: nft_flow_offload: reset dst in route object after setting up flow (CVE-2024-27403)

    * kernel: smb: client: fix UAF in smb2_reconnect_server() (CVE-2024-35870)

    * kernel: net/mlx5: Properly link new fs rules into the tree (CVE-2024-35960)

    * kernel: net: ena: Fix incorrect descriptor free behavior (CVE-2024-35958)

    * kernel: net: hns3: do not allow call hns3_nic_net_open repeatedly (CVE-2021-47400)

    * kernel: octeontx2-af: avoid off-by-one read from userspace (CVE-2024-36957)
