Title
scsi: target: core: Add TMF to tmr_list handling
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Add TMF to tmr_list handling
An abort that is responded to by iSCSI itself is added to tmr_list but does
not go to target core. A LUN_RESET that goes through tmr_list takes a
refcounter on the abort and waits for completion. However, the abort will
be never complete because it was not started in target core.
Unable to locate ITT: 0x05000000 on CID: 0
Unable to locate RefTaskTag: 0x05000000 on CID: 0.

Title
nvme-fc: do not wait in vain when unloading module
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: do not wait in vain when unloading module
The module exit path has race between deleting all controllers and
freeing 'left over IDs'. To prevent double free a synchronization
between nvme_delete_ctrl and ida_destroy has been added by the initial
commit.
There is some logic around trying to prevent from hanging forever in
wait_for_completion, though it does not handling all cases. E.g.
blktests is able to reproduce the situation where the module unload
hangs forever.
If we completely rely on the cleanup code executed from the
nvme_delete_ctrl path, all IDs will be freed eventually. This makes
calling ida_destroy unnecessary. We only have to ensure that all
nvme_delete_ctrl code has been executed before we leave
nvme_fc_exit_module. This is done by flushing the nvme_delete_wq
workqueue.
While at it, remove the unused nvme_fc_wq workqueue too.

To prevent double free a synchronization\nbetween nvme_delete_ctrl and ida_destroy has been added by the initial\ncommit.\n\nThere is some logic around trying to prevent from hanging forever in\nwait_for_completion, though it does not handling all cases. E.g.\nblktests is able to reproduce the situation where the module unload\nhangs forever.\n\nIf we completely rely on the cleanup code executed from the\nnvme_delete_ctrl path, all IDs will be freed eventually. This makes\ncalling ida_destroy unnecessary. We only have to ensure that all\nnvme_delete_ctrl code has been executed before we leave\nnvme_fc_exit_module. This is done by flushing the nvme_delete_wq\nworkqueue.\n\nWhile at it, remove the unused nvme_fc_wq workqueue too."

Title
netfilter: nf_conntrack_h323: Add protection for bmp length out of range
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_h323: Add protection for bmp length out of range
UBSAN load reports an exception of BRK#5515 SHIFT_ISSUE:Bitwise shifts
that are out of bounds for their data type.
vmlinux get_bitmap(b=75) + 712
<net/netfilter/nf_conntrack_h323_asn1.c:0>
vmlinux decode_seq(bs=0xFFFFFFD008037000, f=0xFFFFFFD008037018, level=134443100) + 1956
<net/netfilter/nf_conntrack_h323_asn1.c:592>
vmlinux decode_choice(base=0xFFFFFFD0080370F0, level=23843636) + 1216
<net/netfilter/nf_conntrack_h323_asn1.c:814>
vmlinux decode_seq(f=0xFFFFFFD0080371A8, level=134443500) + 812
<net/netfilter/nf_conntrack_h323_asn1.c:576>
vmlinux decode_choice(base=0xFFFFFFD008037280, level=0) + 1216
<net/netfilter/nf_conntrack_h323_asn1.c:814>
vmlinux DecodeRasMessage() + 304
<net/netfilter/nf_conntrack_h323_asn1.c:833>
vmlinux ras_help() + 684
<net/netfilter/nf_conntrack_h323_main.c:1728>
vmlinux nf_confirm() + 188
<net/netfilter/nf_conntrack_proto.c:137>
Due to abnormal data in skb->data, the extension bitmap length
exceeds 32 when decoding ras message then uses the length to make
a shift operation. It will change into negative after several loop.
UBSAN load could detect a negative shift as an undefined behaviour
and reports exception.
So we add the protection to avoid the length exceeding 32. Or else
it will return out of range error and stop decoding.

The attacker can be anywhere on the internet.\nAC:L - The 7-bit extension-bitmap length field is read verbatim from the packet, so the attacker simply sets it above 32 to force the out-of-range shift \u2014 deterministic, single packet, no timing or memory-layout dependency.\nPR:N - The helper runs on the very first packet of the flow (the trace shows it invoked from nf_confirm()), before any application-level state, credentials, or connection setup exist. A completely unauthenticated remote host triggers it.\nUI:N - Packet processing happens in softirq context on the conntrack hook with no involvement from any local user or administrator.\nS:U - The undefined behavior and its consequences are confined to the kernel of the host running the conntrack helper; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The out-of-range shift produces a garbage value in a local bitmap variable; the byte reads are still covered by nf_h323_error_boundary() and nothing is returned to the attacker, so there is no read primitive or information disclosure.\nI:N - There is no out-of-bounds write and no corruption of adjacent state \u2014 the extension loop remains bounded by f-\u003eub, so the effect is a misparse of the attacker\u0027s own message rather than modification of kernel data.\nA:H - On kernels built with the UBSAN shift sanitizer in trap mode (widely deployed on Android/vendor kernels, and the exact configuration in the bug report) the out-of-range shift raises a BRK exception and panics the kernel, so one unauthenticated remote packet takes the box down."

Title
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in
ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after
ip6_route_mpath_notify(), in the cleanup phase.

"value": "AV:L - The vulnerability is triggered by an RTM_NEWROUTE message sent over an AF_NETLINK/NETLINK_ROUTE socket via sendmsg(), which requires local access to the system. There is no remote packet-processing path into ip6_route_multipath_add().\nAC:L - The attacker creates both sides of the condition: they drop the last reference themselves and can widen the window arbitrarily by supplying many nexthops, by setting RTA_EXPIRES=0 so the non-rtnl gc softirq reaps the route, and by lowering net.ipv6.route.gc_interval inside their own netns, with unlimited retries. syzbot reproduced it, confirming reliable triggerability.\nPR:L - rtnetlink_rcv_msg() only requires netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the network namespace\u0027s user namespace, so any unprivileged local user obtains it with `unshare -Urn`. Multipath ECMP routes are addable in that namespace using RTNH_F_ONLINK gateways, which bypasses gateway reachability validation.\nUI:N - The entire sequence is performed by the attacker\u0027s own process in a single netlink transaction; no victim action, mount, or other interaction is needed.\nS:U - The use-after-free corrupts kernel heap memory and is exploited within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - rt6_fill_node() reads the freed kmalloc-512 fib6_info and copies its contents into an RTM_NEWROUTE netlink message returned to the attacker\u0027s socket, including dereferencing pointers taken from freed memory such as rt-\u003efib6_metrics (passed to rtnetlink_put_metrics()), rt-\u003efib6_table, and rt-\u003efib6_nh. Reclaiming the freed slot with controlled data turns this into an arbitrary kernel-memory read leaked directly to userspace.\nI:H - This is a use-after-free on a 512-byte kmalloc object that an unprivileged attacker can spray and reclaim, after which the kernel dereferences attacker-controlled pointers and performs a list_for_each_entry_safe() walk over the freed fib6_siblings list head. That yields controlled pointer traversal and corruption suitable for privilege escalation.\nA:H - The KASAN slab-use-after-free in rt6_fill_node() causes an oops/panic when the freed object is unmapped, poisoned, or reclaimed with invalid pointers, and it can be triggered repeatedly to reliably crash the kernel."

Title
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
The function ice_bridge_setlink() may encounter a NULL pointer dereference
if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently
in nla_for_each_nested(). To address this issue, add a check to ensure that
br_spec is not NULL before proceeding with the nested attribute iteration.

Title
net: sparx5: Fix use after free inside sparx5_del_mact_entry
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sparx5: Fix use after free inside sparx5_del_mact_entry
Based on the static analyzis of the code it looks like when an entry
from the MAC table was removed, the entry was still used after being
freed. More precise the vid of the mac_entry was used after calling
devm_kfree on the mac_entry.
The fix consists in first using the vid of the mac_entry to delete the
entry from the HW and after that to free it.

"value": "AV:A - The vulnerability is driven by Ethernet frames on the L2 segment \u2014 an unauthenticated attacker connected to a Sparx5 switch port populates the MAC table with chosen source MACs, and a MAC roam or FDB age-out makes the bridge emit SWITCHDEV_FDB_DEL_TO_DEVICE into sparx5_del_mact_entry(). No routing is involved, so this is same-broadcast-domain (Adjacent) rather than Network.\nAC:L - The free-then-use is unconditional straight-line code, not a race \u2014 every matching entry deletion frees mact_entry and then reads mact_entry-\u003evid. The attacker controls both the MAC/VID that populates the table and the trigger (moving the same source MAC between ports forces br_fdb_update() to emit the delete notification synchronously), so it is reproducible on demand.\nPR:N - The frame-driven path requires no credentials or account on the switch whatsoever \u2014 MAC learning, roaming, and FDB aging are automatic. The privileged `bridge fdb del` route is only an alternative, strictly weaker trigger.\nUI:N - No victim action is needed; bridge MAC learning, roaming and aging happen automatically in response to attacker-sent frames on an already-configured bridged switch port.\nS:U - The freed object and the corrupted state are both kernel-resident within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Freed slab memory is read back and acted upon, and the object lives in a general kmalloc cache that concurrent GFP_ATOMIC softirq allocations (including the driver\u0027s own attacker-driven switchdev work and skb allocations) can immediately reoccupy, letting an attacker influence and infer freed heap contents. Per use-after-free scoring, UAF primitives generalize to kernel memory disclosure.\nI:H - The stale value read from freed memory is written directly into the hardware MAC-table unlearn command, so the wrong VID is unlearned \u2014 the attacker\u0027s revoked MAC stays programmed and forwarded in hardware while an unrelated victim\u0027s entry can be purged, corrupting switch forwarding and isolation state. As a use-after-free it also carries the general potential for heap-grooming-based write primitives.\nA:H - Dereferencing freed slab memory can oops outright \u2014 the kfree() immediately preceding the read can discard the last-in-use slab page back to the page allocator \u2014 and KASAN/hardened kernels report or panic on it. The attacker can retrigger it continuously by flooding frames with rotating source MACs, and corrupted MAC-table state causes persistent forwarding breakage."

Title
geneve: make sure to pull inner header in geneve_rx()
Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: make sure to pull inner header in geneve_rx()
syzbot triggered a bug in geneve_rx() [1]
Issue is similar to the one I fixed in commit 8d975c15c0cd
("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

{
"lang": "en",
"value": "AV:N - The vulnerable code is the GENEVE UDP encapsulation receive handler for a socket bound to INADDR_ANY on UDP port 6081, reached directly from `udp_rcv()` on a received packet. In collect_md/external mode (standard OVS/OVN cloud overlay) `geneve_lookup_skb()` accepts any remote source address, so any host that can send UDP to the tunnel endpoint reaches `geneve_rx()`.\nAC:L - The attacker fully controls the skb layout: sending the encapsulated packet as IP fragments makes `ip_defrag()` produce a frag_list skb whose linear area ends exactly at the inner Ethernet header, deterministically placing `skb-\u003edata` at `skb-\u003etail` before the ECN read. Outer IP options and geneve option length give additional 4-byte tuning for NIC-driven fragment layouts.\nPR:N - There is no authentication, capability check, or credential validation anywhere on the `ip_rcv` \u2192 `udp_rcv` \u2192 `geneve_udp_encap_recv` \u2192 `geneve_rx` path. An unauthenticated remote peer only needs to send a crafted UDP datagram to the tunnel port.\nUI:N - The bug triggers entirely during softirq packet receive processing on the target host; no local user has to open, mount, or interact with anything.\nS:U - The uninitialized read occurs in kernel network receive context and its effects (ECN decision, packet drop) stay within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:L - The bug reads uninitialized kernel heap memory past the end of the valid skb data, but is strictly bounded to 1 byte (IPv4 TOS) or 2 bytes (IPv6 dsfield) and stays inside the `skb-\u003ehead` allocation. The stale contents are not returned to the attacker directly \u2014 they leak only as a per-packet drop/no-drop oracle from `__INET_ECN_decapsulate()`.\nI:L - The uninitialized byte drives whether the decapsulated packet is dropped and whether CE/ECT(1) marking is applied to tunneled traffic, so data traversing the tunnel can be modified or discarded based on garbage. The amount is minimal and the attacker has no control over the consequence; `INET_ECN_set_ce()`/`set_ect1()` are bounds-checked, so no out-of-bounds write primitive exists.\nA:L - Incorrect ECN decapsulation driven by uninitialized memory causes spurious drops of legitimate GENEVE-tunneled traffic (`err \u003e 1` \u2192 `kfree_skb`), degrading overlay connectivity. There is no kernel crash on production configurations \u2014 the read stays within the `skb-\u003ehead` slab object so KASAN does not fire, and only the KMSAN debug tool reports it."
