Reaching the vulnerable merge requires local presence on the system (module/firmware load or the debugfs time-point/clear handlers), so this is Local rather than Adjacent.\nAC:L - The out-of-bounds write is fully deterministic \u2014 whenever two triggers share a time point and the newer one lacks IWL_FW_INI_APPLY_POLICY_OVERRIDE_DATA with non-empty existing data, the byte offset is unconditionally multiplied by four. There is no race, no memory-layout precondition, and INI debug is enabled by default, so no unusual configuration is needed.\nPR:L - Triggering requires only local access to the code path that (re)initializes the iwlwifi firmware debug configuration, with no authentication step in the path itself and no capability check inside iwl_dbg_tlv_override_trig_node. Between low and high privileges this is scored as the higher-severity Low, consistent with other locally-triggered iwlwifi memory-corruption CVEs.\nUI:N - No victim action is required \u2014 the trigger list is merged automatically at IWL_FW_INI_TIME_POINT_EARLY during normal firmware load, which occurs at boot or whenever the device is brought up.\nS:U - The overflow corrupts kernel slab memory and its impact is confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The heap overflow writes past the krealloc\u0027d node into adjacent slab objects, corrupting neighbouring kernel structures such as pointers and length fields, which can be leveraged into an arbitrary kernel read primitive and disclosure of arbitrary memory.\nI:H - This is an out-of-bounds heap write of attacker-influenced content whose length (roughly 3 x data_len) and payload both come from the trigger TLV, giving a shaped write into adjacent slab objects \u2014 the standard primitive for kernel data/control-flow corruption and privilege escalation.\nA:H - Slab corruption of adjacent objects reliably produces kernel oopses, allocator BUG_ON/hardened-usercopy panics, or later crashes on freeing the smashed neighbours, resulting in a complete denial of service."

Title
net/smc: fix illegal rmb_desc access in SMC-D connection dump
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix illegal rmb_desc access in SMC-D connection dump
A crash was found when dumping SMC-D connections. It can be reproduced
by following steps:
- run nginx/wrk test:
smc_run nginx
smc_run wrk -t 16 -c 1000 -d <duration> -H 'Connection: Close' <URL>
- continuously dump SMC-D connections in parallel:
watch -n 1 'smcss -D'
BUG: kernel NULL pointer dereference, address: 0000000000000030
CPU: 2 PID: 7204 Comm: smcss Kdump: loaded Tainted: G E 6.7.0+ #55

It is possible that the connection is in process of being established
when we dump it. Assumed that the connection has been registered in a
link group by smc_conn_create() but the rmb_desc has not yet been
initialized by smc_buf_create(), thus causing the illegal access to
conn->rmb_desc. So fix it by checking before dump.

Title
tomoyo: fix UAF write bug in tomoyo_write_control()
Summary
In the Linux kernel, the following vulnerability has been resolved:
tomoyo: fix UAF write bug in tomoyo_write_control()
Since tomoyo_write_control() updates head->write_buf when write()
of long lines is requested, we need to fetch head->write_buf after
head->io_sem is held. Otherwise, concurrent write() requests can
cause use-after-free-write and double-free problems.
Severity
No CVSS data available.

Title
llc: call sock_orphan() at release time
Summary
In the Linux kernel, the following vulnerability has been resolved:
llc: call sock_orphan() at release time
syzbot reported an interesting trace [1] caused by a stale sk->sk_wq
pointer in a closed llc socket.
In commit ff7b11aa481f ("net: socket: set sock->sk to NULL after
calling proto_ops::release()") Eric Biggers hinted that some protocols
are missing a sock_orphan(), we need to perform a full audit.
In net-next, I plan to clear sock->sk from sock_orphan() and
amend Eric patch to add a warning.

Title
scsi: core: Move scsi_host_busy() out of host lock for waking up EH handler
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Move scsi_host_busy() out of host lock for waking up EH handler
Inside scsi_eh_wakeup(), scsi_host_busy() is called & checked with host
lock every time for deciding if error handler kthread needs to be waken up.
This can be too heavy in case of recovery, such as:
- N hardware queues
- queue depth is M for each hardware queue
- each scsi_host_busy() iterates over (N * M) tag/requests
If recovery is triggered in case that all requests are in-flight, each
scsi_eh_wakeup() is strictly serialized, when scsi_eh_wakeup() is called
for the last in-flight request, scsi_host_busy() has been run for (N * M -
1) times, and request has been iterated for (N*M - 1) * (N * M) times.
If both N and M are big enough, hard lockup can be triggered on acquiring
host lock, and it is observed on mpi3mr(128 hw queues, queue depth 8169).
Fix the issue by calling scsi_host_busy() outside the host lock. We don't
need the host lock for getting busy count because host the lock never
covers that.

Title
llc: Drop support for ETH_P_TR_802_2.
Summary
In the Linux kernel, the following vulnerability has been resolved:
llc: Drop support for ETH_P_TR_802_2.
syzbot reported an uninit-value bug below. [0]
llc supports ETH_P_802_2 (0x0004) and used to support ETH_P_TR_802_2
(0x0011), and syzbot abused the latter to trigger the bug.
write$tun(r0, &(0x7f0000000040)={@val={0x0, 0x11}, @val, @mpls={[], @llc={@snap={0xaa, 0x1, ')', "90e5dd"}}}}, 0x16)
llc_conn_handler() initialises local variables {saddr,daddr}.mac
based on skb in llc_pdu_decode_sa()/llc_pdu_decode_da() and passes
them to __llc_lookup().
However, the initialisation is done only when skb->protocol is
htons(ETH_P_802_2), otherwise, __llc_lookup_established() and
__llc_lookup_listener() will read garbage.
The missing initialisation existed prior to commit 211ed865108e
("net: delete all instances of special processing for token ring").
It removed the part to kick out the token ring stuff but forgot to
close the door allowing ETH_P_TR_802_2 packets to sneak into llc_rcv().
Let's remove llc_tr_packet_type and complete the deprecation.

Title
llc: make llc_ui_sendmsg() more robust against bonding changes
Summary
In the Linux kernel, the following vulnerability has been resolved:
llc: make llc_ui_sendmsg() more robust against bonding changes
syzbot was able to trick llc_ui_sendmsg(), allocating an skb with no
headroom, but subsequently trying to push 14 bytes of Ethernet header [1]
Like some others, llc_ui_sendmsg() releases the socket lock before
calling sock_alloc_send_skb().
Then it acquires it again, but does not redo all the sanity checks
that were performed.
This fix:
- Uses LL_RESERVED_SPACE() to reserve space.
- Check all conditions again after socket lock is held again.
- Do not account Ethernet header for mtu limitation.
[1]

Title
tcp: add sanity checks to rx zerocopy
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: add sanity checks to rx zerocopy
TCP rx zerocopy intent is to map pages initially allocated
from NIC drivers, not pages owned by a fs.
This patch adds to can_map_frag() these additional checks:
- Page must not be a compound one.
- page->mapping must be NULL.
This fixes the panic reported by ZhangPeng.
syzbot was able to loopback packets built with sendfile(),
mapping pages owned by an ext4 file to TCP rx zerocopy.

A purely remote peer cannot supply page-cache or compound pages into the receive frags, since those come from the local NIC/page_pool allocator.\nAC:L - The syzbot reproducer is fully deterministic with no race window and no dependence on memory layout: sendfile() guarantees PAGE_SIZE frags at offset 0 pointing at ext4 page-cache pages, and loopback delivers them unchanged to the same socket\u0027s receive queue. Follow-on inode eviction is likewise triggered on demand by the attacker via O_TRUNC/unlink+close.\nPR:L - Every step is available to an ordinary unprivileged user \u2014 tcp_mmap() performs no capability check, TCP_ZEROCOPY_RECEIVE is unconditionally compiled in under CONFIG_MMU, and sendfile() on a file the user owns needs no privilege. No CAP_NET_ADMIN or namespace trickery is required at all.\nUI:N - A single unprivileged process performs the entire sequence against itself via a loopback self-connect; no victim process must be running, and no administrator or user action is needed.\nS:U - The corruption is confined to the kernel\u0027s own page-cache/rmap accounting and the attacking process\u0027s address space, managed by the same security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Because the page is mapped outside the inode\u0027s i_mmap tree, filemap_unaccount_folio()\u0027s recovery path resets mapcount and subtracts the PTE\u0027s reference, letting the page be freed and reallocated while the attacker retains a valid read-only PTE to it \u2014 an arbitrary-read window into whatever kernel data (slab objects, page tables, other processes\u0027 pages) subsequently occupies that physical page.\nI:H - The dropped reference plus the later munmap-time page_remove_rmap()/put_page() drives _mapcount and the page refcount negative, producing a double-free of a buddy-allocator page that can be handed out twice and used as a write primitive into kernel-owned memory. The mismatched rmap/_nr_pages_mapped accounting for compound folios corrupts kernel state directly.\nA:H - This is exactly the reported crash \u2014 truncating the file makes filemap_unaccount_folio() hit VM_BUG_ON_FOLIO(folio_mapped(folio)) and panic the kernel; on non-DEBUG_VM builds it produces \"BUG: Bad page cache\"/bad-page-state taints and freelist corruption that destabilizes the whole system."

Title
ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()
syzbot found __ip6_tnl_rcv() could access unitiliazed data [1].
Call pskb_inet_may_pull() to fix this, and initialize ipv6h
variable after this call as it can change skb->head.

"value": "AV:N - The vulnerable code is in the IPv6 tunnel receive path, reached directly from `ipv6_rcv()` \u2192 `ip6_protocol_deliver_rcu()` \u2192 `gre_rcv()`/`ip6ip6_rcv()`/`ip4ip6_rcv()` when a host has an ip6tnl, ip6gre, ERSPAN or collect_md tunnel endpoint configured. A remote attacker triggers it purely by sending a crafted IPv6 packet (proto 47/41/4/137) with a truncated inner header.\nAC:L - The attacker fully controls the packet: simply emitting an outer IPv6+GRE header with zero/short inner payload deterministically reaches `dscp_ecn_decapsulate()` with the inner header absent from the linear area. No race, no memory-layout grooming, and no condition outside the attacker\u0027s control is required.\nPR:N - Tunnel decapsulation is completely unauthenticated \u2014 `ip6_tnl_rcv_ctl()`/`ip6_tnl_lookup()` only compare addresses and keys, and wildcard, `collect_md` and fallback tunnels match arbitrary sources. The attacker needs no account or credentials on the target.\nUI:N - Processing happens automatically in softirq context when the packet is received; no local user has to open, mount, or click anything.\nS:U - The uninitialized read and the out-of-bounds DSCP write are confined to kernel memory managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:L - KMSAN confirms uninitialized kernel heap memory is read and consumed by `__INET_ECN_decapsulate()`, and the outcome is remotely observable (packet dropped vs. delivered, plus the ratelimited \"non-ECT from %pI6 with DS=%#x\" log), giving a repeatable oracle over stale heap contents. The exposure is strictly bounded to a couple of bytes within the skb\u0027s own buffer rather than an arbitrary read.\nI:L - On tunnels configured with `IP6_TNL_F_RCV_DSCP_COPY`, `ipv6_change_dsfield()`/`ipv4_change_dsfield()` perform an unchecked read-modify-write beyond the packet data (unlike the bounds-checked `INET_ECN_set_ce()`), modifying kernel memory that does not belong to the packet \u2014 in the zero-tailroom case the first bytes of `struct skb_shared_info`. The corruption is a few bytes at a fixed offset, not an arbitrary write.\nA:H - The unchecked DSCP write can land on `skb_shared_info`\u0027s `meta_len` and `frag_list` pointer bytes, corrupting a kernel pointer that is later dereferenced during skb traversal/free, yielding an oops; garbage-driven ECN decisions additionally cause spurious `rx_frame_errors` drops of tunnel traffic, and the condition is a hard KMSAN/instrumented-kernel abort. Any unauthenticated remote peer can repeat it indefinitely."
