CVSS: 6.8EPSS: 0%CPEs: 2EXPL: 0CVE-2024-35843 – iommu/vt-d: Use device rbtree in iopf reporting path
https://notcve.org/view.php?id=CVE-2024-35843
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Use device rbtree in iopf reporting path The existing I/O page fault handler currently locates the PCI device by calling pci_get_domain_bus_and_slot(). This function searches the list of all PCI devices until the desired device is found. To improve lookup efficiency, replace it with device_rbtree_find() to search the device within the probed device rbtree. The I/O page fault is initiated by the device, which does not have any synchronization mechanism with the software to ensure that the device stays in the probed device tree. Theoretically, a device could be released by the IOMMU subsystem after device_rbtree_find() and before iopf_get_dev_fault_param(), which would cause a use-after-free problem. Add a mutex to synchronize the I/O page fault reporting path and the IOMMU release device path. This lock doesn't introduce any performance overhead, as the conflict between I/O page fault reporting and device releasing is very rare. • https://git.kernel.org/stable/c/3d39238991e745c5df85785604f037f35d9d1b15 https://git.kernel.org/stable/c/def054b01a867822254e1dda13d587f5c7a99e2a https://access.redhat.com/security/cve/CVE-2024-35843 https://bugzilla.redhat.com/show_bug.cgi?id=2281276 • CWE-416: Use After Free •

In the Linux kernel, the following vulnerability has been resolved: mptcp: use OPTION_MPTCP_MPJ_SYNACK in subflow_finish_connect() subflow_finish_connect() uses four fields (backup, join_id, thmac, none) that may contain garbage unless OPTION_MPTCP_MPJ_SYNACK has been set in mptcp_parse_option() En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mptcp: use OPTION_MPTCP_MPJ_SYNACK en subflow_finish_connect() subflow_finish_connect() usa cuatro campos (backup, join_id, thmac, none) que pueden contener basura a menos que se haya configurado OPTION_MPTCP_MPJ_SYNACK en mptcp_parse_option() CVE-2024-35840 is a vulnerability in the Linux kernel’s Multipath TCP (MPTCP) implementation. It occurs because the subflow_finish_connect() function may handle uninitialized data in certain fields if a specific MPTCP option (OPTION_MPTCP_MPJ_SYNACK) is not correctly set during option parsing. This could lead to unpredictable behavior in MPTCP connections. The issue has been resolved by ensuring proper initialization and handling of these fields. • https://git.kernel.org/stable/c/f296234c98a8fcec94eec80304a873f635d350ea https://git.kernel.org/stable/c/413b913507326972135d2977975dbff8b7f2c453 https://git.kernel.org/stable/c/51e4cb032d49ce094605f27e45eabebc0408893c https://git.kernel.org/stable/c/ad3e8f5c3d5c53841046ef7a947c04ad45a20721 https://git.kernel.org/stable/c/76e8de7273a22a00d27e9b8b7d4d043d6433416a https://git.kernel.org/stable/c/be1d9d9d38da922bd4beeec5b6dd821ff5a1dfeb https://access.redhat.com/security/cve/CVE-2024-35840 https://bugzilla.redhat.com/show_bug.cgi?id=2281282 •
CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2024-35839 – netfilter: bridge: replace physindev with physinif in nf_bridge_info
https://notcve.org/view.php?id=CVE-2024-35839
In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: replace physindev with physinif in nf_bridge_info An skb can be added to a neigh->arp_queue while waiting for an arp reply. Where original skb's skb->dev can be different to neigh's neigh->dev. For instance in case of bridging dnated skb from one veth to another, the skb would be added to a neigh->arp_queue of the bridge. As skb->dev can be reset back to nf_bridge->physindev and used, and as there is no explicit mechanism that prevents this physindev from been freed under us (for instance neigh_flush_dev doesn't cleanup skbs from different device's neigh queue) we can crash on e.g. this stack: arp_process neigh_update skb = __skb_dequeue(&neigh->arp_queue) neigh_resolve_output(..., skb) ... br_nf_dev_xmit br_nf_pre_routing_finish_bridge_slow skb->dev = nf_bridge->physindev br_handle_frame_finish Let's use plain ifindex instead of net_device link. To peek into the original net_device we will use dev_get_by_index_rcu(). Thus either we get device and are safe to use it or we don't get it and drop skb. • https://git.kernel.org/stable/c/c4e70a87d975d1f561a00abfe2d3cefa2a486c95 https://git.kernel.org/stable/c/7ae19ee81ca56b13c50a78de6c47d5b8fdc9d97b https://git.kernel.org/stable/c/9325e3188a9cf3f69fc6f32af59844bbc5b90547 https://git.kernel.org/stable/c/544add1f1cfb78c3dfa3e6edcf4668f6be5e730c https://git.kernel.org/stable/c/9874808878d9eed407e3977fd11fee49de1e1d86 https://access.redhat.com/security/cve/CVE-2024-35839 https://bugzilla.redhat.com/show_bug.cgi?id=2281284 •
