CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: sync read disk super and set block size
When the user performs a btrfs mount, the block device is not set
correctly. The user sets the block size of the block device to 0x4000
by executing the BLKBSZSET command.
Since the block size change also changes the mapping->flags value, this
further affects the result of the mapping_min_folio_order() calculation.
Let's analyze the following two scenarios:
Scenario 1: Without executing the BLKBSZSET command, the block size is
0x1000, and mapping_min_folio_order() returns 0;
Scenario 2: After executing the BLKBSZSET command, the block size is
0x4000, and mapping_min_folio_order() returns 2.
do_read_cache_folio() allocates a folio before the BLKBSZSET command
is executed. This results in the allocated folio having an order value
of 0. Later, after BLKBSZSET is executed, the block size increases to
0x4000, and the mapping_min_folio_order() calculation result becomes 2.
This leads to two undesirable consequences:
1. filemap_add_folio() triggers a VM_BUG_ON_FOLIO(folio_order(folio) <
mapping_min_folio_order(mapping)) assertion.
2. The syzbot report [1] shows a null pointer dereference in
create_empty_buffers() due to a buffer head allocation failure.
Synchronization should be established based on the inode between the
BLKBSZSET command and read cache page to prevent inconsistencies in
block size or mapping flags before and after folio allocation.

| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: toshiba_haps: Fix memory leaks in add/remove routines
toshiba_haps_add() leaks the haps object allocated by it if it returns
an error after allocating that object successfully.
toshiba_haps_remove() does not free the object pointed to by
toshiba_haps before clearing that pointer, so it becomes unreachable
allocated memory.
Address these memory leaks by using devm_kzalloc() for allocating
the memory in question. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: handle changing device dma map requirements
The initial state of dma_needs_unmap may be false, but change to true
while mapping the data iterator. Enabling swiotlb is one such case that
can change the result. The nvme driver needs to save the mapped dma
vectors to be unmapped later, so allocate as needed during iteration
rather than assume it was always allocated at the beginning. This fixes
a NULL dereference from accessing an uninitialized dma_vecs when the
device dma unmapping requirements change mid-iteration. |
| An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. |
| A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service. |
| .NET Elevation of Privilege Vulnerability |
| There is a stored Cross‑Site Scripting (XSS) vulnerability in Esri Portal for ArcGIS versions 11.2 and below that may allow a remote, authenticated attacker to create a crafted link that can be saved as a new location when moving an existing item, which could potentially execute arbitrary JavaScript code in a victim’s browser. Exploitation does not require any privileges and can be performed by an anonymous user. |
| There is a cross‑site scripting (XSS) vulnerability in Esri Portal for ArcGIS Experience Builder versions 11.1 and below on Windows and Linux that allows a remote, authenticated attacker with low‑privileged access to create a crafted link which, when clicked, could potentially execute arbitrary JavaScript code in the victim’s browser. Exploitation requires basic authenticated access but does not require elevated or administrative privileges, indicating low privileges are required. |
| There is an improper access control issue in ArcGIS Server versions 11.3 and below on Windows and Linux which, under unique circumstances, could allow a remote, low‑privileged authenticated attacker to access secure services published to a standalone (unfederated) ArcGIS Server instance. Successful exploitation results in unauthorized access to protected services outside the attacker’s originally assigned authorization boundary, constituting a scope change. If exploited, this issue would have a high impact on confidentiality, a low impact on integrity, and no impact on the availability of the software. |
| There is a difficult‑to‑exploit improper authentication issue in the Home application for Esri Portal for ArcGIS versions 11.2 and below on Windows and Linux, and ArcGIS Enterprise versions 11.1 and below on Kubernetes, which under unique circumstances could allow a remote, authenticated attacker with low‑privileged access to compromise the confidentiality, integrity, and availability of the software. Successful exploitation allows the attacker to cross an authentication and authorization boundary beyond their originally assigned access, resulting in a scope change. |

| IBM Concert 1.0.0 through 2.1.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. |
| IBM Concert 1.0.0 through 2.1.0 stores potentially sensitive information in log files that could be read by a local user. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Sanitize payload size to prevent member overflow
In qla27xx_copy_fpin_pkt() and qla27xx_copy_multiple_pkt(), the frame_size
reported by firmware is used to calculate the copy length into
item->iocb. However, the iocb member is defined as a fixed-size 64-byte
array within struct purex_item.
If the reported frame_size exceeds 64 bytes, subsequent memcpy calls will
overflow the iocb member boundary. While extra memory might be allocated,
this cross-member write is unsafe and triggers warnings under
CONFIG_FORTIFY_SOURCE.
Fix this by capping total_bytes to the size of the iocb member (64 bytes)
before allocation and copying. This ensures all copies remain within the
bounds of the destination structure member. |
| In the Linux kernel, the following vulnerability has been resolved:
can: ems_usb: ems_usb_read_bulk_callback(): fix URB memory leak
Fix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:
gs_usb_receive_bulk_callback(): fix URB memory leak").
In ems_usb_open(), the URBs for USB-in transfers are allocated, added to
the dev->rx_submitted anchor and submitted. In the complete callback
ems_usb_read_bulk_callback(), the URBs are processed and resubmitted. In
ems_usb_close() the URBs are freed by calling
usb_kill_anchored_urbs(&dev->rx_submitted).
However, this does not take into account that the USB framework unanchors
the URB before the complete function is called. This means that once an
in-URB has been completed, it is no longer anchored and is ultimately not
released in ems_usb_close().
Fix the memory leak by anchoring the URB in the
ems_usb_read_bulk_callback() to the dev->rx_submitted anchor. |
