Title
nfsd: provide locking for v4_end_grace
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: provide locking for v4_end_grace
Writing to v4_end_grace can race with server shutdown and result in
memory being accessed after it was freed - reclaim_str_hashtbl in
particularly.
We cannot hold nfsd_mutex across the nfsd4_end_grace() call as that is
held while client_tracking_op->init() is called and that can wait for
an upcall to nfsdcltrack which can write to v4_end_grace, resulting in a
deadlock.
nfsd4_end_grace() is also called by the landromat work queue and this
doesn't require locking as server shutdown will stop the work and wait
for it before freeing anything that nfsd4_end_grace() might access.
However, we must be sure that writing to v4_end_grace doesn't restart
the work item after shutdown has already waited for it. For this we
add a new flag protected with nn->client_lock. It is set only while it
is safe to make client tracking calls, and v4_end_grace only schedules
work while the flag is set with the spinlock held.
So this patch adds a nfsd_net field "client_tracking_active" which is
set as described. Another field "grace_end_forced", is set when
v4_end_grace is written. After this is set, and providing
client_tracking_active is set, the laundromat is scheduled.
This "grace_end_forced" field bypasses other checks for whether the
grace period has finished.
This resolves a race which can result in use-after-free.

After this is set, and providing\nclient_tracking_active is set, the laundromat is scheduled.\nThis \"grace_end_forced\" field bypasses other checks for whether the\ngrace period has finished.\n\nThis resolves a race which can result in use-after-free."

Title
net: mscc: ocelot: Fix crash when adding interface under a lag
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mscc: ocelot: Fix crash when adding interface under a lag
Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag")
fixed a similar issue in the lan966x driver caused by a NULL pointer dereference.
The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic
and is susceptible to the same crash.
This issue specifically affects the ocelot_vsc7514.c frontend, which leaves
unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as
it uses the DSA framework which registers all ports.
Fix this by checking if the port pointer is valid before accessing it.
Severity
No CVSS data available.

This does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - The missing bounds check lets a peer-controlled payload_len make auth callbacks treat memory beyond the received control buffer as valid input. This is an unbounded kernel out-of-bounds read, so confidentiality impact is High.\nI:H - Although described as an out-of-bounds read, the auth_x callbacks can decrypt and clear claimed reply data in place based on attacker-controlled lengths. With the required conservative scoring, this can plausibly become kernel memory corruption and is scored as High integrity impact.\nA:H - Reading or cryptographically processing beyond the allocated control buffer can fault, corrupt memory, or otherwise crash the kernel. The malformed handshake frame can be sent repeatedly by the malicious peer."

Title
libceph: replace overzealous BUG_ON in osdmap_apply_incremental()
Summary
In the Linux kernel, the following vulnerability has been resolved:
libceph: replace overzealous BUG_ON in osdmap_apply_incremental()
If the osdmap is (maliciously) corrupted such that the incremental
osdmap epoch is different from what is expected, there is no need to
BUG. Instead, just declare the incremental osdmap to be invalid.

Title
libceph: make free_choose_arg_map() resilient to partial allocation
Summary
In the Linux kernel, the following vulnerability has been resolved:
libceph: make free_choose_arg_map() resilient to partial allocation
free_choose_arg_map() may dereference a NULL pointer if its caller fails
after a partial allocation.
For example, in decode_choose_args(), if allocation of arg_map->args
fails, execution jumps to the fail label and free_choose_arg_map() is
called. Since arg_map->size is updated to a non-zero value before memory
allocation, free_choose_arg_map() will iterate over arg_map->args and
dereference a NULL pointer.
To prevent this potential NULL pointer dereference and make
free_choose_arg_map() more resilient, add checks for pointers before
iterating.

Cleanup then deterministically dereferences a NULL `args` or `weight_set` pointer in the vulnerable code.\nPR:N - The attacker needs no local privileges on the vulnerable kernel host, and Ceph deployments can use auth-none/no-key configurations or process maps from a malicious configured peer. When uncertain between authentication-dependent and unauthenticated deployments, the higher severity PR:N is selected.\nUI:N - Once a CephFS/RBD/libceph client is connected, OSD maps are processed asynchronously by the kernel networking/messenger path. No additional victim action is needed for a remote peer to deliver the crafted map.\nS:U - The impact is within the vulnerable kernel client host and does not cross a separate security authority such as a hypervisor, VM boundary, or IOMMU boundary. This is a standard kernel availability impact with unchanged scope.\nC:N - The fixed flaw is a NULL pointer dereference during error cleanup after partial allocation failure. It does not provide an attacker-controlled memory read primitive.\nI:N - The direct vulnerable operation is dereferencing NULL in cleanup, not an out-of-bounds write, UAF, or controlled write. No integrity-modifying primitive is exposed by this fix.\nA:H - A NULL pointer dereference in kernel context can oops or panic the system, and the crafted map can be sent repeatedly by the remote peer. This is a high availability impact."

In the Linux kernel, the following vulnerability has been resolved:
libceph: return the handler error from mon_handle_auth_done()
Currently any error from ceph_auth_handle_reply_done() is propagated
via finish_auth() but isn't returned from mon_handle_auth_done(). This
results in higher layers learning that (despite the monitor considering
us to be successfully authenticated) something went wrong in the
authentication phase and reacting accordingly, but msgr2 still trying
to proceed with establishing the session in the background. In the
case of secure mode this can trigger a WARN in setup_crypto() and later
lead to a NULL pointer dereference inside of prepare_auth_signature().

No additional victim action is required once the client is connecting to the monitor.\nS:U - The impact is within the same kernel security authority as the vulnerable libceph client code. It does not cross a VM, sandbox, or separate authorization boundary.\nC:N - The investigated failure path is a WARN followed by a NULL pointer dereference through uninitialized secure-mode crypto state. There is no evidence of an information disclosure primitive.\nI:N - The bug does not provide an attacker-controlled write or control-flow corruption primitive. The observed and described impact is failure to stop session setup after an auth error, leading to a null dereference.\nA:H - The secure-mode path can dereference a NULL crypto request in kernel context and produce an oops or panic depending on system policy.

Title
bpf: Fix reference count leak in bpf_prog_test_run_xdp()
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix reference count leak in bpf_prog_test_run_xdp()
syzbot is reporting
unregister_netdevice: waiting for sit0 to become free. Usage count = 2
problem. A debug printk() patch found that a refcount is obtained at
xdp_convert_md_to_buff() from bpf_prog_test_run_xdp().
According to commit ec94670fcb3b ("bpf: Support specifying ingress via
xdp_md context in BPF_PROG_TEST_RUN"), the refcount obtained by
xdp_convert_md_to_buff() will be released by xdp_convert_buff_to_md().
Therefore, we can consider that the error handling path introduced by
commit 1c1949982524 ("bpf: introduce frags support to
bpf_prog_test_run_xdp()") forgot to call xdp_convert_buff_to_md().
Severity
No CVSS data available.

Title
net/mlx5e: Don't store mlx5e_priv in mlx5e_dev devlink priv
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Don't store mlx5e_priv in mlx5e_dev devlink priv
mlx5e_priv is an unstable structure that can be memset(0) if profile
attaching fails, mlx5e_priv in mlx5e_dev devlink private is used to
reference the netdev and mdev associated with that struct. Instead,
store netdev directly into mlx5e_dev and get mdev from the containing
mlx5_adev aux device structure.
This fixes a kernel oops in mlx5e_remove when switchdev mode fails due
to change profile failure.
$ devlink dev eswitch set pci/0000:00:03.0 mode switchdev
Error: mlx5_core: Failed setting eswitch to offloads.

net: can: j1939: j1939_xtp_rx_rts_session_active(): deactivate session upon receiving the second rts
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: can: j1939: j1939_xtp_rx_rts_session_active(): deactivate session upon receiving the second rts
Since j1939_session_deactivate_activate_next() in j1939_tp_rxtimer() is
called only when the timer is enabled, we need to call
j1939_session_deactivate_activate_next() if we cancelled the timer.
Otherwise, refcount for j1939_session leaks, which will later appear as
| unregister_netdevice: waiting for vcan0 to become free. Usage count = 2.

Title
nvme-tcp: fix NULL pointer dereferences in nvmet_tcp_build_pdu_iovec
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: fix NULL pointer dereferences in nvmet_tcp_build_pdu_iovec
Commit efa56305908b ("nvmet-tcp: Fix a kernel panic when host sends an invalid H2C PDU length")
added ttag bounds checking and data_offset
validation in nvmet_tcp_handle_h2c_data_pdu(), but it did not validate
whether the command's data structures (cmd->req.sg and cmd->iov) have
been properly initialized before processing H2C_DATA PDUs.
The nvmet_tcp_build_pdu_iovec() function dereferences these pointers
without NULL checks. This can be triggered by sending H2C_DATA PDU
immediately after the ICREQ/ICRESP handshake, before
sending a CONNECT command or NVMe write command.
Attack vectors that trigger NULL pointer dereferences:
1. H2C_DATA PDU sent before CONNECT → both pointers NULL
2. H2C_DATA PDU for READ command → cmd->req.sg allocated, cmd->iov NULL
3. H2C_DATA PDU for uninitialized command slot → both pointers NULL
The fix validates both cmd->req.sg and cmd->iov before calling
nvmet_tcp_build_pdu_iovec(). Both checks are required because:
- Uninitialized commands: both NULL
- READ commands: cmd->req.sg allocated, cmd->iov NULL
- WRITE commands: both allocated

Both checks are required because:\n- Uninitialized commands: both NULL\n- READ commands: cmd-\u003ereq.sg allocated, cmd-\u003eiov NULL\n- WRITE commands: both allocated"

"value": "AV:N - The vulnerable code is in the NVMe over TCP target receive path and is reachable by sending NVMe/TCP PDUs to the target TCP listener. A remote peer can send ICREQ followed by malformed H2C_DATA over the network.\nAC:L - No race or hard-to-control state is required for the pre-CONNECT trigger; the attacker only needs to send a valid IC handshake and then an H2C_DATA PDU with coherent length fields. The required packet sequence is deterministic.\nPR:N - The simplest trigger occurs after ICREQ/ICRESP but before CONNECT, before host NQN allow-list checks, controller creation, or DH-HMAC-CHAP authentication are reached. Thus an unauthenticated network peer can reach the vulnerable handler on a non-TLS or plaintext-accepted target port.\nUI:N - Exploitation does not require any victim user action after the target service is listening. The attacker sends protocol messages directly to the NVMe/TCP target.\nS:U - The impact is within the vulnerable kernel/target system\u2019s own security authority. There is no VM escape, IOMMU bypass, or cross-authority boundary change.\nC:N - The bug is a NULL pointer dereference of uninitialized command buffers, not an out-of-bounds read or use-after-free. The investigated paths support a crash impact, not disclosure of kernel memory.\nI:N - The dereferences are to NULL command buffer pointers and do not provide a practical arbitrary write or control-flow primitive. The fix and related history characterize the issue as invalid state leading to NULL dereference.\nA:H - The vulnerable dereference occurs in kernel context and can produce an oops or panic in the nvmet-tcp workqueue path. Repeated unauthenticated network triggers can deny availability of the target system or service."
