Title
vsock: Ignore signal/timeout on connect() if already established
Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Ignore signal/timeout on connect() if already established
During connect(), acting on a signal/timeout by disconnecting an already
established socket leads to several issues:
1. connect() invoking vsock_transport_cancel_pkt() ->
virtio_transport_purge_skbs() may race with sendmsg() invoking
virtio_transport_get_credit(). This results in a permanently elevated
`vvs->bytes_unsent`. Which, in turn, confuses the SOCK_LINGER handling.
2. connect() resetting a connected socket's state may race with socket
being placed in a sockmap. A disconnected socket remaining in a sockmap
breaks sockmap's assumptions. And gives rise to WARNs.
3. connect() transitioning SS_CONNECTED -> SS_UNCONNECTED allows for a
transport change/drop after TCP_ESTABLISHED. Which poses a problem for
any simultaneous sendmsg() or connect() and may result in a
use-after-free/null-ptr-deref.
Do not disconnect socket on signal/timeout. Keep the logic for unconnected
sockets: they don't linger, can't be placed in a sockmap, are rejected by
sendmsg().

Title
net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end()
The loops in 'qede_tpa_cont()' and 'qede_tpa_end()', iterate
over 'cqe->len_list[]' using only a zero-length terminator as
the stopping condition. If the terminator was missing or
malformed, the loop could run past the end of the fixed-size array.
Add an explicit bound check using ARRAY_SIZE() in both loops to prevent
a potential out-of-bounds access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

"value": "AV:N - The vulnerable TPA/GRO completion-descriptor handling runs in the qede NAPI receive path, driven entirely by packets arriving from the network on a Marvell/QLogic FastLinQ NIC typically deployed in internet-facing datacenter and cloud servers. The `len_list[]` contents are produced by hardware coalescing of remotely-sent TCP segments, so an off-path/remote peer supplies the data that drives the loop.\nAC:L - The overrun occurs whenever the aggregation fills all `len_list[]` slots leaving no zero terminator, a condition an attacker steers directly by sending high-rate/crafted TCP bursts that maximize the number of BDs per aggregation. No unpredictable memory layout or victim state is required, and the attack can be repeated indefinitely until it lands.\nPR:N - Sending Ethernet/TCP traffic to a host requires no credentials or account on the target; the RX path processes frames before any authentication or socket-level authorization. The driver parses the completion descriptor unconditionally in softirq context.\nUI:N - Packet reception and TPA aggregation happen automatically in the NAPI poll routine with no involvement from any logged-in user. No file must be opened, no filesystem mounted, and no configuration action performed.\nS:U - The out-of-bounds read and the resulting skb fragment-array corruption are confined to kernel memory under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The loop reads past `len_list[]` into adjacent DMA-mapped completion-ring memory, and the resulting garbage lengths are used to build skb fragments at arbitrary offsets/sizes within RX pages, which `napi_gro_receive()` then delivers up the stack to sockets \u2014 leaking uninitialized kernel/RX-ring memory to a remote peer.\nI:H - `qede_fill_frag_skb()` increments `tpa_info-\u003efrag_id` with no `MAX_SKB_FRAGS` bound, so the extra iterations write page pointer/offset/length triplets past `skb_shinfo(skb)-\u003efrags[]` \u2014 a controllable heap out-of-bounds write \u2014 and simultaneously over-consume the RX BD ring, corrupting driver state and adjacent slab objects in a way exploitable for control-flow hijack.\nA:H - Overrunning the skb shared-info fragment array and desynchronizing the RX BD ring reliably produces oops/panic (bad page state, DMA unmap of bogus mappings, refcount corruption) in softirq context, taking the machine down. The condition is remotely repeatable, so recovery is not possible while the attacker keeps sending traffic."

Title
s390/ctcm: Fix double-kfree
Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/ctcm: Fix double-kfree
The function 'mpc_rcvd_sweep_req(mpcginfo)' is called conditionally
from function 'ctcmpc_unpack_skb'. It frees passed mpcginfo.
After that a call to function 'kfree' in function 'ctcmpc_unpack_skb'
frees it again.
Remove 'kfree' call in function 'mpc_rcvd_sweep_req(mpcginfo)'.
Bug detected by the clang static analyzer.

MPC TH headers are regenerated per link and not routable, so the attacker must sit on the adjacent channel connection rather than across a routed network.\nAC:L - A single frame with `th_ch_flag = 0xfe` deterministically drives `ctcmpc_unpack_skb()` into `mpc_rcvd_sweep_req()` and the two consecutive `kfree()` calls every time \u2014 no race, no timing window, and no memory-layout precondition outside the attacker\u0027s control.\nPR:N - The attacker needs no account, credential, or capability on the target Linux image; it only has to be the CTC peer, and the path is reachable both in `MPCG_STATE_READY` and during the pre-establishment XID-negotiation states, where no authentication of any kind has occurred.\nUI:N - The remote peer triggers the double free entirely on its own by transmitting one frame on an already-active CTC link; no administrator or user action on the victim system is needed at attack time.\nS:U - The slab corruption occurs in the receiving kernel\u0027s own softirq/tasklet context and its consequences stay within that kernel\u0027s security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - On kernels without freelist hardening the double free leaves the kmalloc-64 percpu freelist self-referential, so repeated allocations hand the same 40-byte object to unrelated kernel structures, yielding an aliasing/use-after-free primitive that exposes arbitrary kernel memory contents to the attacker-controlled objects.\nI:H - The same freelist corruption lets attacker-influenced allocations overlap live kernel objects (type confusion), giving a write primitive over adjacent/aliased kernel data and a realistic path to control-flow hijack \u2014 classic exploitable heap corruption, not a mere accounting error.\nA:H - With `CONFIG_SLAB_FREELIST_HARDENED` the immediate double free hits `BUG_ON(object == fp)` in `set_freepointer()` inside a tasklet, which is fatal in interrupt context; without it the corrupted freelist causes near-certain crashes, and either outcome is re-triggerable at will by the peer."

Title
net: openvswitch: remove never-working support for setting nsh fields
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: remove never-working support for setting nsh fields
The validation of the set(nsh(...)) action is completely wrong.
It runs through the nsh_key_put_from_nlattr() function that is the
same function that validates NSH keys for the flow match and the
push_nsh() action. However, the set(nsh(...)) has a very different
memory layout. Nested attributes in there are doubled in size in
case of the masked set(). That makes proper validation impossible.
There is also confusion in the code between the 'masked' flag, that
says that the nested attributes are doubled in size containing both
the value and the mask, and the 'is_mask' that says that the value
we're parsing is the mask. This is causing kernel crash on trying to
write into mask part of the match with SW_FLOW_KEY_PUT() during
validation, while validate_nsh() doesn't allocate any memory for it:

The third issue with this process is that while trying to convert
the non-masked set into masked one, validate_set() copies and doubles
the size of the OVS_KEY_ATTR_NSH as if it didn't have any nested
attributes. It should be copying each nested attribute and doubling
them in size independently. And the process must be properly reversed
during the conversion back from masked to a non-masked variant during
the flow dump.
In the end, the only two outcomes of trying to use this action are
either validation failure or a kernel crash. And if somehow someone
manages to install a flow with such an action, it will most definitely
not do what it is supposed to, since all the keys and the masks are
mixed up.
Fixing all the issues is a complex task as it requires re-writing
most of the validation code.
Given that and the fact that this functionality never worked since
introduction, let's just remove it altogether. It's better to
re-introduce it later with a proper implementation instead of trying
to fix it in stable releases.

mptcp: fix a race in mptcp_pm_del_add_timer()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix a race in mptcp_pm_del_add_timer()
mptcp_pm_del_add_timer() can call sk_stop_timer_sync(sk, &entry->add_timer)
while another might have free entry already, as reported by syzbot.
Add RCU protection to fix this issue.
Also change confusing add_timer variable with stop_timer boolean.
syzbot report:

"value": "AV:N - The use-after-free is dereferenced inside `mptcp_incoming_options()` while parsing an MPTCP ADD_ADDR echo option received from a remote peer (`tcp_v4_rcv \u2192 tcp_rcv_established \u2192 tcp_data_queue \u2192 mptcp_incoming_options \u2192 mptcp_pm_del_add_timer`), as shown verbatim in the syzbot stack. Any remote MPTCP peer of an internet-facing MPTCP-enabled server reaches this code with ordinary TCP packets.\nAC:L - The attacker controls both sides of the race \u2014 the ADD_ADDR echo can be emitted at will and repeatedly to keep a thread parked in the unlocked window, while the freeing side (`FLUSH_ADDRS`/`DEL_ADDR`/userspace-PM `REMOVE`) is either driven by the PM daemon reacting to the attacker\u0027s own MPTCP address events or issued directly by a local attacker looping netlink calls. Both `mptcp_pm_del_add_timer()` callers are trivially invokable in a tight loop, so the window is hit reliably.\nPR:N - A remote MPTCP peer needs no credentials or privileges on the target \u2014 only an established MPTCP connection, whose keys are what `add_addr_hmac_valid()` checks. Even the netlink half of the race is only `GENL_UNS_ADMIN_PERM`, i.e. CAP_NET_ADMIN reachable by an unprivileged user via `unshare -Urn`, so no real privilege is required anywhere on the path.\nUI:N - Exploitation happens entirely in the kernel\u0027s TCP receive path and the MPTCP path-manager worker; no victim action, mount, or file open is needed.\nS:U - The corruption is confined to kernel slab memory and the compromised component is the kernel itself, so there is no crossing into a different security authority.\nC:H - The freed `mptcp_pm_add_entry` lives in a sprayable general kmalloc cache; after reclaim, `__timer_delete_sync()` reads attacker-groomed memory and a fired `mptcp_pm_add_timer()` re-announces `entry-\u003eaddr` from the reclaimed object, leaking kernel heap contents onto the wire and yielding an arbitrary-read primitive via the confused `entry-\u003esock` pointer.\nI:H - `__timer_delete_sync()` writes into the freed timer during detach, and a timer firing out of a reallocated object drives `sk_reset_timer()`/`__sock_put()` on a fully attacker-controlled `entry-\u003esock` pointer \u2014 a wild-pointer write and refcount decrement suitable for heap grooming into control-flow hijack.\nA:H - KASAN confirms a slab-use-after-free in `__timer_delete_sync()`; unmitigated this reliably corrupts timer-base list state and oopses or panics the kernel, and the race can be re-triggered repeatedly from the network for a persistent denial of service."

Title
mptcp: fix race condition in mptcp_schedule_work()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix race condition in mptcp_schedule_work()
syzbot reported use-after-free in mptcp_schedule_work() [1]
Issue here is that mptcp_schedule_work() schedules a work,
then gets a refcount on sk->sk_refcnt if the work was scheduled.
This refcount will be released by mptcp_worker().
[A] if (schedule_work(...)) {
[B] sock_hold(sk);
return true;
}
Problem is that mptcp_worker() can run immediately and complete before [B]
We need instead :
sock_hold(sk);
if (schedule_work(...))
return true;
sock_put(sk);
[1]
refcount_t: addition on 0; use-after-free.

"value": "AV:N - The vulnerable function is reached directly from the packet receive path (`tcp_input.c` \u2192 `mptcp_incoming_options()` on received MP_FASTCLOSE and DATA_FIN options) and from the mp_fail/close timeouts armed by remote peer behaviour such as a bad DSS checksum or subflow reset. A remote MPTCP peer drives the connection state machine that schedules the work, making this reachable over the network with no local access.\nAC:L - The attacker controls both sides of the race by opening and tearing down large numbers of MPTCP connections/subflows, generating an unbounded stream of work-scheduling events (timer expiry, MP_FASTCLOSE, DATA_FIN, subflow close) that each retry the race. The window is further widened on threaded-softirq/PREEMPT_RT kernels (as in the syzbot trace, `run_ktimerd`) and under vCPU preemption in virtualized deployments, so success is achievable at will through repetition.\nPR:N - No credentials or capabilities are checked anywhere on the path; a remote peer of an MPTCP connection (or an unauthenticated client connecting to an MPTCP-enabled listener) triggers the option-parsing and timeout paths in softirq context. Locally the same code is reachable by any unprivileged user simply creating and closing `IPPROTO_MPTCP` sockets.\nUI:N - The race is triggered entirely by attacker-generated traffic and normal MPTCP connection teardown/timeout processing. No victim action of any kind is required.\nS:U - The corruption is confined to kernel memory within the same security authority; there is no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel use-after-free.\nC:H - The `struct sock` is freed while still referenced, and the freed slab object can be reallocated and read back through the still-live MPTCP socket/timer state, exposing arbitrary kernel heap contents. Use-after-free on a socket object gives an attacker control over the contents of the freed object, enabling kernel memory disclosure.\nI:H - After the premature free, `sock_hold()` performs a refcount increment write at a fixed offset into freed (and potentially reallocated) memory, and the trailing `sock_put()` can re-enter `sk_free()`/`sk_destruct` on that object, producing a double free and freelist corruption. These are established primitives for heap grooming and control-flow hijacking, i.e. full integrity loss.\nA:H - The reported symptom is a refcount underflow warning followed by use-after-free of the MPTCP socket, which readily results in an oops or panic when the freed object is dereferenced by the timer, workqueue, or destructor path. Any UAF of this kind reliably crashes the kernel, and it can be triggered repeatedly."

Title
nvme: nvme-fc: Ensure ->ioerr_work is cancelled in nvme_fc_delete_ctrl()
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme: nvme-fc: Ensure ->ioerr_work is cancelled in nvme_fc_delete_ctrl()
nvme_fc_delete_assocation() waits for pending I/O to complete before
returning, and an error can cause ->ioerr_work to be queued after
cancel_work_sync() had been called. Move the call to cancel_work_sync() to
be after nvme_fc_delete_association() to ensure ->ioerr_work is not running
when the nvme_fc_ctrl object is freed. Otherwise the following can occur:

A malicious or compromised NVMe/FC target (or a peer able to inject frames on the fabric, which may be extended over routed links via FCIP/FCoE) needs no host access to drive both halves.\nAC:L - The attacker controls both sides of the race: it supplies the erroring I/O completions and triggers the association teardown, and during `nvme_fc_delete_association()` every aborted I/O unconditionally re-queues `ioerr_work` (state is DELETING, not RESETTING, so the `check_error` guard passes) after `cancel_work_sync()` has already run, so the work is reliably resurrected whenever I/O is outstanding at delete time.\nPR:N - A remote FC/NVMe-oF peer needs no credentials or privileges on the victim host; the vulnerable path is reached purely through normal transport error completions and fabric port-loss events on an already-established association.\nUI:N - No victim action is required \u2014 connectivity loss and `dev_loss_tmo` expiry delete the controller automatically while in-flight I/O is aborted, with no administrator involvement.\nS:U - The corruption is confined to kernel memory and workqueue state within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `nvme_fc_ctrl` is read after `kfree()` \u2014 the workqueue dereferences the embedded `work_struct` (`work-\u003efunc`, `work-\u003eentry`) and `nvme_fc_ctrl_ioerr_work()`/`nvme_fc_error_recovery()` read `ctrl-\u003ectrl` state from freed memory, a use-after-free that with slab reuse yields an information-disclosure primitive.\nI:H - The workqueue performs `list_del_init(\u0026work-\u003eentry)` and `move_linked_works()` list manipulation writing into the freed object, and `process_one_work()` loads and calls `work-\u003efunc` from it; reclaiming the slab with sprayed data gives an attacker-controlled indirect call and arbitrary-write primitive.\nA:H - The reported failure is an immediate kernel BUG/oops (`list_del corruption ... kernel BUG at lib/list_debug.c:52` in `move_linked_works()` from a `nvme-wq` worker), i.e. a system panic and loss of the storage path."

Title
Input: imx_sc_key - fix memory corruption on unload
Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: imx_sc_key - fix memory corruption on unload
This is supposed to be "priv" but we accidentally pass "&priv" which is
an address in the stack and so it will lead to memory corruption when
the imx_sc_key_action() function is called. Remove the &.
Severity
7.8 (High)

Title
Input: cros_ec_keyb - fix an invalid memory access
Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: cros_ec_keyb - fix an invalid memory access
If cros_ec_keyb_register_matrix() isn't called (due to
`buttons_switches_only`) in cros_ec_keyb_probe(), `ckdev->idev` remains
NULL. An invalid memory access is observed in cros_ec_keyb_process()
when receiving an EC_MKBP_EVENT_KEY_MATRIX event in cros_ec_keyb_work()
in such case.
Unable to handle kernel read from unreadable memory at virtual address 0000000000000028
...
x3 : 0000000000000000 x2 : 0000000000000000
x1 : 0000000000000000 x0 : 0000000000000000
Call trace:
input_event
cros_ec_keyb_work
blocking_notifier_call_chain
ec_irq_thread
It's still unknown about why the kernel receives such malformed event,
in any cases, the kernel shouldn't access `ckdev->idev` and friends if
the driver doesn't intend to initialize them.
Severity
No CVSS data available.
