Remote tunnel packets alone do not invoke `ovs_netdev_tunnel_destroy()`.\nAC:L - This is a race/lifetime bug, but the attacker can control both sides by repeatedly deleting tunnel vports while concurrently driving RCU readers such as vport get/dump, packet execute, or datapath traffic. No rare external condition is required.\nPR:L - Creating and deleting OVS datapaths/vports requires `CAP_NET_ADMIN`, but the OVS Generic Netlink families are netns-aware and use `GENL_UNS_ADMIN_PERM`, making this reachable with CAP_NET_ADMIN in an unprivileged user namespace. This is Low privileges rather than High.\nUI:N - No victim user action is needed once the local attacker can issue the relevant netlink operations. The attacker can trigger creation, deletion, and racing reader activity directly.\nS:U - The vulnerability is a kernel memory lifetime error within the same host kernel security authority. It is a standard local kernel privilege-escalation/DoS class issue, not a VM or hardware boundary escape.\nC:H - The early `netdev_put()` can free the `net_device` while RCU readers still dereference `vport-\u003edev`, creating a use-after-free. Per kernel CVSS guidance, UAFs are scored as High confidentiality impact because they can be developed into kernel memory disclosure primitives.\nI:H - The stale `net_device` pointer can be reused after free by kernel readers/writers and may reach function-pointer-bearing netdev paths. Per guidance, a use-after-free is scored as High integrity impact because heap reuse can enable arbitrary write or code execution.\nA:H - The bug can at minimum crash or oops the kernel through NULL/stale `vport-\u003edev` dereferences and has related observed OVS netdev lifetime splats. A kernel UAF also warrants High availability impact."

It is not directly triggerable by unauthenticated network packets alone.\nAC:L - The attacker can create the needed partial-send condition by controlling the TCP peer or receiver behavior and filling the send buffer, then issuing another send. No race or condition outside attacker control is required.\nPR:L - Setting an already-registered TCP ULP does not require CAP_NET_ADMIN, and ordinary local users can create TCP sockets and call setsockopt/sendmsg. XFRM administration is privileged, but it is not required for this lowest-privilege path to `espintcp_sendmsg`.\nUI:N - Exploitation does not require any victim user action after the attacker has local code execution. The attacker directly drives the socket operations.\nS:U - The impact remains within the kernel and its managed resources on the same host. This is not a VM escape, IOMMU bypass, or cross-authority boundary violation.\nC:H - The stale partial-send offset can produce an out-of-bounds read in the TCP send path, potentially exposing kernel memory through transmitted data. Because the read is not strictly bounded to a small fixed disclosure, high confidentiality impact is appropriate.\nI:H - The corrupted espintcp/sk_msg state can build invalid bvec/socket-buffer references and disturb page or send-buffer accounting, which is a plausible kernel memory integrity primitive. Under the required higher-severity rule for uncertainty, this is scored as high integrity impact.\nA:H - The invalid scatterlist/bvec state can lead to kernel warnings, invalid page references, refcount/accounting corruption, or crashes in the send/cleanup path. A local attacker can repeat the trigger, so availability impact is high."

A broken\nor malicious port partner can therefore drive altmodes to\nALTMODE_DISCOVERY_MAX - 1 via the normal flow, and then send one extra\nDiscover Modes ACK with seven VDOs.  Because the pre-loop check passes,\nthe loop could then writes up to five entries past altmode_desc[].

The\nreverse happens when per-VLAN multicast snooping is disabled.\n\nWhen global multicast snooping is enabled, the bridge iterates over all\nthe bridge ports and enables the per-port multicast context on each\nport. The reverse happens when multicast snooping is disabled.\n\nThe above scheme can result in a situation where both types of contexts\n(per-port and per-{port, VLAN}) are enabled on a single bridge port:\n\n # ip link add name br1 up type bridge mcast_snooping 1 mcast_querier 1 vlan_filtering 1\n # ip link add name dummy1 up master br1 type dummy\n # ip link set dev br1 type bridge mcast_vlan_snooping 1\n # ip link set dev br1 type bridge mcast_snooping 0\n # ip link set dev br1 type bridge mcast_snooping 1\n\nThis is not intended and it is a problem since the commit cited below.\nPrior to this commit, when removing a bridge port,\nbr_multicast_disable_port() would disable the per-port multicast context\nand the per-{port, VLAN} multicast contexts would get disabled when\nflushing VLANs.\n\nAfter this commit, br_multicast_disable_port() only disables the\nper-port multicast context if per-VLAN multicast snooping is disabled.\nIf both types of contexts were enabled on the port when it was removed,\nthe per-port multicast context would remain enabled when freeing the\nbridge port, leading to a use-after-free [1].\n\nFix by preventing the bridge from enabling / disabling the per-port\nmulticast contexts when toggling global multicast snooping if per-VLAN\nmulticast snooping is enabled.\n\n[1]\nODEBUG: free active (active state 0) object: ffff88810f8bda78 object type: timer_list hint: br_ip6_multicast_port_query_expired (net/bridge/br_multicast.c:1927)\nWARNING: lib/debugobjects.c:629 at debug_print_object+0x1b1/0x3e0, CPU#5: swapper/5/0\n[...]\nCall Trace:\n\u003cIRQ\u003e\n__debug_check_no_obj_freed (lib/debugobjects.c:1116)\nkfree (mm/slub.c:2620 mm/slub.c:6250 mm/slub.c:6565)\nkobject_cleanup (lib/kobject.c:689)\nrcu_do_batch (kernel/rcu/tree.c:2617)\nrcu_core (kernel/rcu/tree.c:2869)\nhandle_softirqs (kernel/softirq.c:622)\n__irq_exit_rcu (kernel/softirq.c:656 kernel/softirq.c:496 kernel/softirq.c:735)\nirq_exit_rcu (kernel/softirq.c:752)\nsysvec_apic_timer_interrupt (arch/x86/kernel/apic/apic.c:1061 (discriminator 47) arch/x86/kernel/apic/apic.c:1061 (discriminator 47))\n\u003c/IRQ\u003e"

An attacker must issue `ip link`/`bridge` configuration commands to create the inconsistent multicast state and remove a bridge port.\nAC:L - The reproducer sequence is fully attacker-controlled and deterministic; syzkaller triggered it reliably. The attacker configures the toggle sequence, removes the port, and the orphaned IGMP/MLD query timers fire on schedule without depending on uncontrollable timing or memory layout.\nPR:L - All entry paths require CAP_NET_ADMIN in the target network namespace (rtnetlink at rtnl_newlink, br_ioctl add_del_if, sysfs bridge attributes). Unprivileged local users can obtain this capability by creating a user+network namespace (`unshare -Urn`), which is widely enabled on server and container hosts.\nUI:N - Exploitation requires no action from any other user or victim; the attacker performs the entire bridge setup, state toggling, and port removal themselves.\nS:U - Successful exploitation corrupts kernel memory within the same kernel security domain. This is a standard local kernel memory corruption issue, not a cross-boundary escape such as VM guest-to-host or IOMMU bypass.\nC:H - This is a heap use-after-free on a freed net_bridge_port structure; the timer callback dereferences pmctx-\u003eport-\u003ebr on freed memory. UAF on kernel slab objects enables arbitrary kernel memory reads via heap grooming and reclamation of the freed port object.\nI:H - The UAF occurs in a timer softirq handler that reads and writes through fields of the freed port multicast context, including sending queries via br_multicast_send_query. Kernel heap UAF is exploitable for arbitrary write and control-flow hijack primitives, not merely a crash.\nA:H - The freed port structure is kfree\u0027d while IGMP/MLD own-query timers remain active, producing a debugobjects \"free active timer\" warning and use-after-free in softirq. This reliably causes kernel oops/panic and can be triggered repeatedly to deny service on shared infrastructure such as cloud hosts or software switches."

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipv4: raw: reject IP_HDRINCL packets with ihl \u003c 5\n\nraw_send_hdrinc() validates that the caller-supplied IPv4 header\nfits within the message length:\n\n    iphlen = iph-\u003eihl * 4;\n    err = -EINVAL;\n    if (iphlen \u003e length)\n        goto error_free;\n\n    if (iphlen \u003e= sizeof(*iph)) {\n        /* fix up saddr, tot_len, id, csum, transport_header */\n    }\n\nIt does not, however, reject ihl \u003c 5.  For such a packet the\n\"if (iphlen \u003e= sizeof(*iph))\" branch is skipped, leaving the\ncrafted iphdr untouched, but the packet is still handed to\n__ip_local_out() and onward.  Downstream consumers that read\niph-\u003eihl assume a sane value: net/ipv4/ah4.c:ah_output() in\nparticular subtracts sizeof(struct iphdr) from top_iph-\u003eihl * 4\nand passes the (signed-int-negative, then cast to size_t)\nresult to memcpy(), producing an OOB access of length close to\nSIZE_MAX and a host kernel panic.\n\nAn IPv4 header with ihl \u003c 5 is malformed by definition (RFC 791:\n\"Internet Header Length is the length of the internet header in\n32 bit words ... Note that the minimum value for a correct header\nis 5.\").  The kernel should not be willing to inject such a\npacket into its own output path.\n\nReject \"iphlen \u003c sizeof(*iph)\" alongside the existing\n\"iphlen \u003e length\" check.  This matches the principle that locally\nconstructed packets that re-enter the IP stack must pass the same\nbasic sanity tests that a foreign packet would be subjected to.\n\nOnce this lands, the \"if (iphlen \u003e= sizeof(*iph))\" wrapper around\nthe fixup branch becomes redundant; left in place to keep the\npatch minimal and backport-friendly.  A follow-up can unwrap it.\n\nNote that commit 86f4c90a1c5c (\"ipv4, ipv6: ensure raw socket\nmessage is big enough to hold an IP header\") ensures the message\nbuffer is large enough to hold an iphdr, but does not constrain\nthe self-reported iph-\u003eihl.\n\nReachability: the malformed packet source is any caller with\nCAP_NET_RAW, including an unprivileged process in a user+net\nnamespace on a kernel with CONFIG_USER_NS=y.  The reproduced AH\ncrash also requires a matching xfrm AH policy on the outgoing\nroute; a container granted CAP_NET_ADMIN can install that state\nand policy in its netns.  Loopback bypasses xfrm_output, so the\ntrigger uses a real netdev.\n\nReproduced on UML + KASAN: kernel-mode fault at addr 0x0 with\nmemcpy_orig at the crash site.  Same shape reproduces inside a\nrootless Docker container with --cap-add NET_ADMIN on a stock\ndistro kernel."

              "value": "AV:A - The bug is in the Bluetooth HCI LE extended-advertising path; a remote/adjacent peer can deliver the LE Extended Advertising Set Terminated HCI event that frees adv_info while hci_cmd_sync_work waits on the controller during scan-response/advertising-data updates on phones and other BLE devices.\nAC:L - This is a use-after-free race between hci_cmd_sync_work and hci_rx_work where the attacker controls the terminating side by repeatedly initiating BLE connections/terminations during the up-to-2s HCI command wait, and can also drive the setup side via MGMT advertising commands.\nPR:N - An adjacent Bluetooth attacker needs no account, credentials, or capabilities on the victim; exploitation only requires the victim stack to be configuring BLE advertising (normal on Android phones, laptops, and IoT) while the attacker sends over-the-air BLE traffic to trigger hci_le_ext_adv_term_evt.\nUI:N - No deliberate victim action is required beyond a device running Bluetooth with LE advertising updates (common default behavior); the attacker triggers the race remotely without social engineering, file opens, or mounts.\nS:U - Impact is kernel heap corruption and potential local privilege escalation within the same kernel security domain; it does not cross a VM, container, or IOMMU boundary.\nC:H - Multiple UAF paths read freed adv_info (e.g., eir_create_scan_rsp/adv_data) and retain dangling pointers across __hci_cmd_sync_status waits, enabling slab reuse and arbitrary kernel memory disclosure via heap grooming.\nI:H - KASAN shows a post-free write to adv_info (scan_rsp_changed); similar paths write adv_data_changed and tx_power on freed objects, providing exploitable heap corruption for arbitrary kernel writes and code execution.\nA:H - Use-after-free on adv_info in hci_cmd_sync_work can cause immediate kernel oops/panic or hung BLE subsystem during advertising reconfiguration, and is reachable from unauthenticated adjacent BLE interaction on actively advertising devices."
