CVSS v3.1 |
| Access of resource using incompatible type ('type confusion') in .NET Core allows an unauthorized attacker to deny service over a network. |
| Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to deny service over a network. |
| IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API endpoint. The POST /api/v1/validate/code endpoint accepts user-supplied Python code and executes it directly using Python's built-in exec() function without sandboxing, input validation, or privilege restrictions, enabling any authenticated user to execute arbitrary system commands with the full privileges of the Langflow server process. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phy: clean the sfp upstream if phy probing fails
Sashiko reported that we don't call sfp_bus_del_upstream() in the probe
failure path, so let's add it, otherwise the sfp-bus is left with a
dangling 'upstream' field, that may be used later on during SFP events.
This issue existed before the generic phylib sfp support, back when
drivers were calling phy_sfp_probe themselves. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: check for PCI upstream bridge existence
pci_upstream_bridge() returns NULL if the device is on a root bus. If
8821CE is installed in the system with such a PCI topology, the probing
routine will crash. This has probably been unnoticed as 8821CE is mostly
supplied in laptops where there is a PCI-to-PCI bridge located upstream
from the device. However the card might be installed on a system with
different configuration.
Check if the bridge does exist for the specific workaround to be applied.
Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool. |

PCI/ASPM: Fix link state exit during switch upstream function removal
Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to
avoid use-after-free"), we would free the ASPM link only after the last
function on the bus pertaining to the given link was removed.
That was too late. If function 0 is removed before sibling function,
link->downstream would point to free'd memory after.
After above change, we freed the ASPM parent link state upon any function
removal on the bus pertaining to a given link.
That is too early. If the link is to a PCIe switch with MFD on the upstream
port, then removing functions other than 0 first would free a link which
still remains parent_link to the remaining downstream ports.
The resulting GPFs are especially frequent during hot-unplug, because
pciehp removes devices on the link bus in reverse order.
On that switch, function 0 is the virtual P2P bridge to the internal bus.
Free exactly when function 0 is removed -- before the parent link is
obsolete, but after all subordinate links are gone.

| openSIS Classic 9.3 contains an authenticated path traversal vulnerability in the legacy messaging sent-mail attachment download functionality that allows an authenticated attacker to read arbitrary files on the server via crafted path traversal sequences. |
| In the Linux kernel, the following vulnerability has been resolved:
drm: Set old handle to NULL before prime swap in change_handle
There was a potential race condition in change_handle. The ioctl
briefly had a single object with two idr entries; a concurrent
gem_close could delete the object and remove one of the handles
while leaving the other one dangling, which could subsequently
be dereferenced for a use-after-free.
To fix this, do the same dance that gem_close itself does.
(f6cd7daecff5 drm: Release driver references to handle before making it available again)
First idr_replace the old handle to NULL. Later, if the prime
operations are successful, actually close it.
create_tail required a similar dance to avoid a similar problem.
(bd46cece51a3 drm/gem: Fix race in drm_gem_handle_create_tail())
It idr_allocs the new handle with NULL, then swaps in the correct
object later to avoid races. We don't need to do that here, since
the only operations that could race are drm_prime, and
change_handle holds the prime lock for the entire duration.
v2: cleanups of error paths |
| Esri ArcGIS Server contains an unrestricted file upload vulnerability. An unauthenticated attacker could exploit this issue by uploading a crafted file to the affected endpoint. Successful exploitation could allow arbitrary file upload, potentially allowing for other attacks. This issue impacts all versions of ArcGIS Server on Windows and Linux 12.0 and prior. This issue does not impact ArcGIS Enterprise for Kubernetes. |
| Esri ArcGIS Server contains a directory traversal vulnerability. ArcGIS Enterprise on Kubernetes is not impacted. An unauthenticated attacker could exploit this issue by sending crafted path parameters. Successful exploitation could allow overwriting sensitive files on the system. Abuse of this issue can allow full administrative access to ArcGIS Server, with high impact to confidentiality, integrity, and availability. This issue impacts all versions of ArcGIS Server on Windows and Linux 12.0 and prior. This issue does not impact ArcGIS Enterprise for Kubernetes. |
| In the Linux kernel, the following vulnerability has been resolved:
debugobjects: Don't call fill_pool() in early boot hardirq context
When booting a debug PREEMPT_RT kernel on an ARM64 system, a "inconsistent
{HARDIRQ-ON-W} -> {IN-HARDIRQ-W} usage" lockdep warning message was
reported to the console.
During early boot, interrupts are enabled before the scheduler is
enabled. In this window (before SYSTEM_SCHEDULING is set) interrupts can
fire and in the hard interrupt context handler attempt to fill the pool
This can lead to a deadlock when the interrupt occurred when the interrupt
hits a region which holds a lock that is required to be taken in the
allocation path.
Add a new can_fill_pool() helper and reorder the exception rule and forbid
this scenario by excluding allocations from hard interrupt context. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix NULL pointer dereference
PCIe errors detected by a Root Port or Downstream Port cause error
recovery services to run on all subordinate devices regardless of
administrative state.
The .error_detected() callback, bnxt_io_error_detected(), disables
and synchronizes IRQs via bnxt_disable_int_sync(), which calls
bnxt_cp_num_to_irq_num() to map completion rings to IRQs using
bp->bnapi.
Since bp->bnapi is allocated on NIC open and freed on NIC close, PCIe
error recovery on a closed NIC can dereference a NULL pointer.
Check if bp->bnapi is NULL before disabling and synchronizing IRQs. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix the ACK parser to extract the SACK table for parsing
Fix modification of the received skbuff in rxrpc_input_soft_acks() and a
potential incorrect access of the buffer in a fragmented UDP packet (the
packet would probably have to be deliberately pre-generated as fragmented)
when AF_RXRPC tries to extract the contents of the SACK table by copying
out the contents of the SACK table into a buffer before attempting to parse
AF_RXRPC assumes that it can just call skb_condense() and then validly
access the SACK table from skb->data and that it will be a flat buffer -
but skb_condense() can silently fail to do anything under some
circumstances.
Note that whilst rxrpc_input_soft_acks() should be able to parse extended
ACKs, the rest of AF_RXRPC doesn't currently support that.
Further, there's then no need to call skb_condense() in rxrpc_input_ack(),
so don't. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/display: fix oops in suspend/shutdown without display
The xe driver keeps track of whether to probe display, and whether
display hardware is there, using xe->info.probe_display. It gets set to
false if there's no display after intel_display_device_probe(). However,
the display may also be disabled via fuses, detected at a later time in
intel_display_device_info_runtime_init().
In this case, the xe driver does for_each_intel_crtc() on uninitialized
mode config in xe_display_flush_cleanup_work(), leading to a NULL
pointer dereference, and generally calls display code with display info
cleared.
Check for intel_display_device_present() after
intel_display_device_info_runtime_init(), and reset
xe->info.probe_display as necessary. Also do unset_display_features()
for completeness, although display runtime init has already done
that. This will need to be unified across all cases later.
Move intel_display_device_info_runtime_init() call slightly earlier,
similar to i915, to avoid a bunch of unnecessary setup for no display
cases.
Note #1: The xe driver has no business doing low level display plumbing
like for_each_intel_crtc() to begin with. It all needs to happen in
display code.
Note #2: The actual bug is present already in commit 44e694958b95
("drm/xe/display: Implement display support"), but the oops was likely
introduced later at commit ddf6492e0e50 ("drm/xe/display: Make display
suspend/resume work on discrete").

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync
roc_abort_sync() can deadlock with roc_work(). roc_work() holds
dev->mt76.mutex, while cancel_work_sync() waits for roc_work()
to finish. If the caller already owns the same mutex, both
sides block and no progress is possible.
This deadlock can occur during station removal when
mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() ->
mt7921_roc_abort_sync() invokes cancel_work_sync() while
roc_work() is still running and holding dev->mt76.mutex.
This avoids the mutex deadlock and preserves exactly-once
work ownership. |

sctp: disable BH before calling udp_tunnel_xmit_skb()
udp_tunnel_xmit_skb() / udp_tunnel6_xmit_skb() are expected to run with
BH disabled. After commit 6f1a9140ecda ("add xmit recursion limit to
tunnel xmit functions"), on the path:
udp(6)_tunnel_xmit_skb() -> ip(6)tunnel_xmit()
dev_xmit_recursion_inc()/dec() must stay balanced on the same CPU.
Without local_bh_disable(), the context may move between CPUs, which can
break the inc/dec pairing. This may lead to incorrect recursion level
detection and cause packets to be dropped in ip(6)_tunnel_xmit() or
__dev_queue_xmit().
Fix it by disabling BH around both IPv4 and IPv6 SCTP UDP xmit paths.
In my testing, after enabling the SCTP over UDP:

| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Reject SIOCATMARK on non-stream sockets
SIOCATMARK reports whether the receive queue is at the urgent mark for
MSG_OOB.
In AF_UNIX, MSG_OOB is supported only for SOCK_STREAM sockets.
SOCK_DGRAM and SOCK_SEQPACKET reject MSG_OOB in sendmsg() and recvmsg(),
so they should not support SIOCATMARK either.
Return -EOPNOTSUPP for non-stream sockets before checking the receive
queue. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: fix pedit partial COW leading to page cache corruption
tcf_pedit_act() computes the COW range for skb_ensure_writable()
once before the key loop using tcfp_off_max_hint, but the hint does
not account for the runtime header offset added by typed keys. This
can leave part of the write region un-COW'd.
Fix by moving skb_ensure_writable() inside the per-key loop where
the actual write offset is known, and add overflow checking on the
offset arithmetic. For negative offsets (e.g. Ethernet header edits
at ingress), use skb_cow() to COW the headroom instead. Guard
offset_valid() against INT_MIN, where negation is undefined. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btmtk: validate WMT event SKB length before struct access
btmtk_usb_hci_wmt_sync() casts the WMT event response SKB data to
struct btmtk_hci_wmt_evt (7 bytes) and struct btmtk_hci_wmt_evt_funcc
(9 bytes) without first checking that the SKB contains enough data.
A short firmware response causes out-of-bounds reads from SKB tailroom.
Use skb_pull_data() to validate and advance past the base WMT event
header. For the FUNC_CTRL case, pull the additional status field bytes
before accessing them. |
