In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/sdma7.0: replace BUG_ON() with WARN_ON() There's no need to crash the kernel for these cases. (cherry picked from commit 9723a8bed3aa251a26bee4583bac9d8fb064dd44)

CTI-Transmute is affected by a stored cross-site scripting (XSS) vulnerability in the conversion graph used to visualise converted MISP and STIX content. Attacker-controlled values originating from converted CTI data were passed to multiple HTML-parsing sinks in the graph user interface without sufficient neutralisation. In particular, node labels, node sublabels, edge labels, node properties, edge properties, and node types could contain crafted HTML or JavaScript content. The Pivotick graph library renders some of these values through HTML-parsing operations. Consequently, a malicious value such as an HTML element containing an event handler could be interpreted as markup rather than displayed as plain text. The first remediation explicitly notes that Pivotick rendered node and edge labels as HTML and therefore introduced escaping before data was handed to the graph renderer. A separate vulnerable sink was present in the Open raw JSON functionality. The raw object associated with a graph node was inserted into a new document using document.write() and an interpolated HTML string. Crafted JSON content could therefore break out of the intended <pre> element and inject executable markup. The fix replaced this construction with DOM APIs and assigns the JSON using textContent. The initial correction did not cover all Pivotick rendering paths. A subsequent patch addressed additional XSS vectors in the graph properties panel. Values derived from the original CTI object—including property names, property values, hash algorithm names, child attributes, edge properties, and STIX object types—could still reach Pivotick's HTML resolver. According to the patch, Pivotick's tryResolveHTMLElement processes string values using template.innerHTML, allowing malicious markup to execute when a graph node is hovered over or selected. The complete remediation therefore: * HTML-escapes node labels, node sublabels, and edge labels before they are passed to Pivotick. * Restricts graph node type values to a safe identifier character set. * Wraps node and edge property values in DOM elements populated through textContent, preventing Pivotick from treating attacker-controlled strings as HTML. * Replaces the raw-JSON popup's interpolated document.write() with DOM construction and textContent.

In the Linux kernel, the following vulnerability has been resolved: pppoe: reload header pointer after dev_hard_header() pppoe_sendmsg() saves a pointer to the PPPoE header before calling dev_hard_header(). Device header callbacks are allowed to reallocate the skb head, invalidating pointers into it. This can happen when a send is blocked in copy_from_user() while the first non-Ethernet port is added to an empty team device. The team's delegated GRE header callback then expands the skb head. PPPoE subsequently writes six bytes through the stale pointer into the freed head. Reload the PPPoE header through the skb's network-header offset after device header creation. pskb_expand_head() updates that offset when it relocates the head.

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Return NULL on error in active_instance Avoid returning &node->base when node is NULL due to OOM during GFP_ATOMIC allocation. Discovered using AI-assisted static analysis confirmed by Intel Product Security. (cherry picked from commit 6029bc064f0b1bac184203a50fbaaf070fa18832)

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix 32-bit overflow in CWSR total size calculation total_cwsr_size was computed in 32-bit before being used as a BO/SVM allocation size. With large ctx_save_restore_area_size and debug_memory_size multiplied by the XCC count, the product can wrap, yielding an undersized CWSR save area that firmware later overruns. Promote total_cwsr_size to u64 and use check_add_overflow()/ check_mul_overflow() in both kfd_queue_acquire_buffers() and kfd_queue_release_buffers(). (cherry picked from commit 319f7e13423ae3f486b9aea82f9ad2d6af0ee608)

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: printer: fix infinite loop in printer_read() printer_read() uses the same variable for the requested copy size and the number of bytes actually copied to user space. copy_to_user() returns the number of bytes not copied, so when it fails to copy anything, the computed copied length becomes zero. In that case len, buf, current_rx_bytes and current_rx_buf are left unchanged. If RX data is available and the user buffer remains unwritable, the read loop can repeat indefinitely. Track the copied length separately and return -EFAULT, or the number of bytes already copied, if an iteration makes no progress.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: extend conn_hash lookup critical sections Using RCU-protected pointers outside the critical sections without refcount is incorrect and may result to UAF. Extend critical section to cover both hci_conn_hash lookup and use of the returned conn. Add surrounding rcu_read_lock() also when return value is not used, in preparation for RCU lockdep requirement to hci_lookup_le_connect(). This avoids concurrent deletion of the conn before we are done dereferencing it. Also, make sure to hold hdev->lock when accessing hdev->accept_list.

In the Linux kernel, the following vulnerability has been resolved: libceph: refresh auth->authorizer_buf{,_len} after authorizer update ceph_x_create_authorizer() caches au->buf->vec.iov_base and au->buf->vec.iov_len in struct ceph_auth_handshake. These cached values are then used by the messenger connect code when sending the authorizer. ceph_x_update_authorizer() can rebuild the authorizer when a newer service ticket is available. If the rebuilt authorizer no longer fits in the existing buffer, ceph_x_build_authorizer() drops its reference to au->buf and allocates a new one. If this is the final reference, ceph_buffer_put() frees the old ceph_buffer and its vec.iov_base, but auth->authorizer_buf still points at that freed memory. A subsequent msgr1 reconnect can therefore queue the stale pointer and trigger a KASAN slab-use-after-free in _copy_from_iter() while tcp_sendmsg() copies the authorizer. Refresh auth->authorizer_buf and auth->authorizer_buf_len after a successful authorizer rebuild so the messenger sends the current buffer.
