CVSS v3.1 |
| Dell ObjectScale, versions prior to 4.3.0.1, contain(s) a Path Traversal vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Information tampering. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: check return value of nvmet_tcp_set_queue_sock
The return value of nvmet_tcp_set_queue_sock() is currently ignored in
nvmet_tcp_tls_handshake_done(). If it fails (e.g., due to the socket
not being in TCP_ESTABLISHED state), the socket callbacks will not be
properly set, leading to queue and socket leakage.
Fix this by capturing the return value and calling
nvmet_tcp_schedule_release_queue() on failure to ensure proper cleanup. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: fix integer overflow in immediate data length check
imm_buf->len is a user-controlled uint32_t received from the network.
Adding it to imm_data_offset without overflow checking allows a
malicious initiator to send len=0xFFFFFFFF, causing req_size to wrap
around to a small value, bypassing the bounds check, and subsequently
passing a ~4GB length to sg_init_one().
Use check_add_overflow() to detect wrapping before the comparison. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: addrconf: bail out of dad_failure when state is no longer POSTDAD
addrconf_dad_failure() transitions ifp->state from DAD to POSTDAD
via addrconf_dad_end(), which drops ifp->lock on return. The lock
is re-acquired after net_info_ratelimited(). A concurrent
ipv6_del_addr() can take the lock in that window, set ifp->state
to DEAD and run list_del_rcu(&ifp->if_list).
addrconf_dad_failure() then overwrites DEAD with ERRDAD at errdad:
and schedules a new dad_work. The work calls ipv6_del_addr()
again, hitting the already-poisoned list entry:
general protection fault: 0000 [#1] SMP NOPTI
CPU: 4 PID: 217 Comm: kworker/4:1
Workqueue: ipv6_addrconf addrconf_dad_work
RIP: 0010:ipv6_del_addr+0xe9/0x280
RAX: dead000000000122
Call Trace:
addrconf_dad_stop+0x113/0x140
addrconf_dad_work+0x28c/0x430
process_one_work+0x1eb/0x3b0
worker_thread+0x4d/0x400
kthread+0x104/0x140
ret_from_fork+0x35/0x40
Fold the addrconf_dad_end() logic into addrconf_dad_failure() under
a single ifp->lock critical section. The STABLE_PRIVACY branch
temporarily drops ifp->lock around address regeneration, so at
lock_errdad: verify the state is still POSTDAD before transitioning
to ERRDAD; bail out otherwise to avoid overwriting a state set by
another path while the lock was released. |
| In the Linux kernel, the following vulnerability has been resolved:
OPP: Fix race between OPP addition and lookup
A race exists between dev_pm_opp_add_dynamic() and
dev_pm_opp_find_freq_exact():
CPU0 (add) CPU1 (lookup)
------------------------------- ------------------------------
_opp_add()
mutex_lock()
list_add(&new_opp->node, head)
mutex_unlock() _opp_table_find_key()
mutex_lock()
dev_pm_opp_get(opp)
kref_get()
mutex_unlock()
kref_init(&new_opp->kref)
dev_pm_opp_put()
kref_put_mutex()
The newly added OPP is inserted into the list before its kref is
initialized. A concurrent lookup can find this OPP and increment its
reference count while it is still uninitialized, leading to refcount
corruption and a potential premature free.
Fix this by initializing ->kref and ->opp_table before making the OPP
visible via list_add(). This ensures any concurrent lookup observes a
fully initialized object.

| In the Linux kernel, the following vulnerability has been resolved:
vxlan: Fix potential null-ptr-deref in vxlan_gro_prepare_receive().
udp_tunnel_sock_release() could set sk->sk_user_data to NULL
while vxlan_gro_prepare_receive() is running.
Let's check if rcu_dereference_sk_user_data() is NULL after
skb_gro_remcsum_init(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: fix OOB access from firmware tx status queue ID
ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] where ts.qid is a
4-bit hardware field (0-15), but the txq array only has
ATH9K_NUM_TX_QUEUES (10) entries. A qid >= 10 causes an OOB array
access.
Add a bounds check on ts.qid before using it as an array index. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer
In rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit
descriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both
firmware-controlled). The result can exceed RTK_PCI_RX_BUF_SIZE (11478),
causing an out-of-bounds read from the pre-allocated DMA buffer when
skb_put_data copies new_len bytes. The USB transport already validates
this (rtw_usb_rx_data_put checks against RTW_USB_MAX_RECVBUF_SZ); the
PCIe path does not.
Add a check that new_len does not exceed the DMA buffer size. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers
rtw88 stores an ieee80211_hw pointer via pci_set_drvdata() at probe
time, but io_error_detected() and io_resume() retrieve it as a
net_device pointer. This causes netif_device_detach/attach to
operate on an ieee80211_hw struct, reading and writing at wrong
offsets.
Use ieee80211_stop_queues/wake_queues instead, consistent with
every other queue stop/start path in the driver. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: handle CB.InitCallBackState3 requests without a server record
The cache manager callback path now attaches the server record to an
incoming call through the rxrpc peer's app data. That association is
not guaranteed to exist for every callback request, and most callback
handlers already tolerate that case.
Make CB.InitCallBackState3 follow the same pattern by checking whether a
server record was attached before using it. If the peer is not mapped
to a server record, trace the request and ignore it, matching the
existing behaviour for other unmatched callback requests.
This keeps the callback handler consistent with the rest of the cache
manager service and avoids depending on peer state that may not be
available for a given request. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix potential infinite loop in rxrpc_recvmsg()
Fix the wait in rxrpc_recvmsg() also take check the oob queue. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: serialize kernel accept preallocation with socket teardown
rxrpc_kernel_charge_accept() reads rx->backlog without any
socket/backlog synchronization and passes that raw pointer into
rxrpc_service_prealloc_one(). A concurrent rxrpc_discard_prealloc()
sets rx->backlog = NULL and frees the backlog rings, so a kernel
preallocation worker can keep using a freed struct rxrpc_backlog
while updating *_backlog_head/tail and array slots.
Serialize the state check and backlog lookup with the socket lock,
and reject kernel preallocation once teardown has disabled
listening or discarded the service backlog. |
| In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: fix potential UAF on meter attach failure
While attaching a newly created meter attach_meter() function makes
the new meter visible to other CPUs but can still fail afterwards.
On failure, it detaches the meter back and returns an error.
However, this is an unexpected behavior for the ovs_meter_cmd_set()
that uses a plain kfree(meter) on attach failure without waiting for
RCU readers to stop using it, assuming it was never visible.
This is never a problem for ovs-vswitchd as it always creates meters
before creating any flows that use them. But the UAF can be triggered
with a custom application using uAPI:
BUG: KASAN: slab-use-after-free in ovs_meter_execute (net/openvswitch/meter.c:653)

...
netlink_sendmsg (af_netlink.c:1900)
Fix that by making sure attach_meter() doesn't make the meter visible
until all the checks are done and the function can't fail anymore.
This also makes sure the "hash" value is calculated after the potential
re-sizing of the table.

Bluetooth: ISO: avoid deadlocks in iso_sock_timeout
iso_sock_timeout() takes lock_sock, so sync disabling the timer while
holding that lock may deadlock.
iso_sock_timeout() may also run concurrently with iso_conn_del(), which
leads to UAF
[Task 1] [Task hdev->workqueue]
iso_sock_timeout iso_conn_del
iso_conn_hold_unless_zero iso_chan_del
`------------> iso_conn_put
caller frees hcon
iso_conn_put
iso_conn_free
conn->hcon->iso_data = NULL; /* UAF */
Fix the deadlock by removing the disable from the lock_sock sections.
Move the timer from iso_conn to iso_pinfo to decouple it from iso_conn
which may need to be freed in lock_sock section. Convert some of the
clear_timer to disable_timer. |
| IBM Documentation Offline 1.0.0 through 1.4.1 could allow a remote attacker to execute arbitrary code due to improper control of file paths. |
| NVIDIA Triton Inference Server for Linux contains a vulnerability where a user could cause files outside the model repository to be read, written to, or modified by providing a path in the model name to the Triton MLflow plugin. A successful exploit of this vulnerability might lead to denial of service and information disclosure. |
| IBM Documentation Offline 1.0.0 through 1.4.1 could allow a remote attacker to execute arbitrary code due to improper output neutralization for logs. |
| In Progress ShareFile Storage Zones Controller v5.12.5 and below, a party with valid zone credentials can perform path traversal using resumable upload initiation endpoint, allowing the party to write arbitrary content to any location writable by the application's service account. This may result in the execution of attacker-supplied code. |
| In Progress ShareFile Storage Zones Controller versions <= 5.12.5 and <= 6.0.2, an authenticated zone administrator can exploit improper validation in the download preparation flow, enabling attacker-controlled files to be written outside the intended preparation directory. This can lead to remote code execution in v5 versions. Remote code execution is not confirmed on v6 versions. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: xilinx-ams: fix out-of-bounds channel lookup in event handling
ams_event_to_channel() may return a pointer past the end of
dev->channels when no matching scan_index is found. This can lead
to invalid memory access in ams_handle_event().
Add a bounds check in ams_event_to_channel() and return NULL when
no channel is found. Also guard the caller to safely handle this
case. |
