Improper verification of the source of a communication channel in the DNS resolver in Amazon FreeRTOS-Plus-TCP before V4.4.2 might allow remote third-party to insert a chosen address into the device's DNS cache via a forged DNS reply. To remediate this issue, users should upgrade to version V4.4.2 and enable ipconfigDNS_CHECK_REPLY_SOURCE_IP.

Researchers warn that hackers could soon exploit a maximum-severity vulnerability (CVE-2026-103849) affecting Magento and Adobe Commerce, potentially allowing them to execute arbitrary PHP code on store servers. [...]

IBM i 7.3, 7.4, 7.5, and 7.6 could allow a local attacker to bypass NFS version restrictions due to improper enforcement of the export version flag.

IBM Db2 Genius Hub 1.0 could allow a local attacker to obtain sensitive information due to improper verification of cryptographic signature.

IBM i 7.3, 7.4, 7.5, and 7.6 could allow a local attacker to obtain sensitive information due to missing subtree checks during file handle resolution.

IBM Db2 Genius Hub 1.0 could allow a remote authenticated attacker to bypass security restrictions due to a missing initialization vector in the cryptographic algorithm.

Openwave Webtop Media Transcoder does not enforce administrator-defined file type restrictions to restrict the file-types to be converted. This may allow an authenticated user to process and convert unintended document types if bypassing the Webmail experience.

Integer overflow in OpenModSim (<=1.11.0), leading to denial of service

`lopdf::Document::load_mem` (and the other `load*` entry points) parses nested PDF arrays and dictionaries with unbounded recursion. A small crafted PDF whose Catalog contains a deeply nested array (`/X [[[ … ]]]`, on the order of 10,000 levels) exhausts the call stack and aborts the process with `SIGABRT`. Because this is a stack-overflow abort rather than a `panic!`, it cannot be caught with `catch_unwind`: any service that parses untrusted PDF input with lopdf can be crashed by a ~21 KB file

## Summary The MCP Apps UI resource (an interactive DataStore table rendered in the host's webview/iframe) communicates with its parent via `postMessage`. Its inbound `message` listener performs no `event.origin` validation, and its outbound messages are sent with target origin `'*'`. Any window/frame able to reach the document can inject data into the table and interfere with the MCP UI handshake, and the UI's own JSON-RPC messages are broadcast without an origin restriction. ## Affected code

### Impact A path traversal vulnerability in the `revision` command allowed a crafted migration name supplied via the `-m` argument to escape the intended migrations directory. Under specific conditions, an attacker could cause the tool to create a `.sql` file in an arbitrary location writable by the user executing the command. This issue is only exploitable if an attacker can influence the migration name passed to the `revision` command, such as through an insecure automation or CI/CD pipelin

In the Linux kernel, the following vulnerability has been resolved: afs: Fix missing NULL pointer check in afs_break_some_callbacks() Fix afs_break_some_callbacks() to check to see if afs_lookup_volume_rcu() returned NULL (e.g. the specified volume is unknown).

In the Linux kernel, the following vulnerability has been resolved: afs: Fix the volume AFS_VOLUME_RM_TREE is set on Fix afs_insert_volume_into_cell() to set AFS_VOLUME_RM_TREE on the volume replaced, not the new volume, as it's now removed from the cell's volume tree. This will cause the old volume to be removed from the tree twice and the new volume never to be removed.

In the Linux kernel, the following vulnerability has been resolved: drm/xe/pf: Don't attempt to process FAST_REQ or EVENT relays Currently defined VF/PF relay actions use regular REQUEST messages only and the PF shouldn't attempt to handle FAST_REQUEST nor EVENT messages as this would result in breaking the VFPF ABI protocol and also might trigger an assert on the PF side. (cherry picked from commit 1714d360fc5ae2e0886a69e979095d9c7ff3568a)

In the Linux kernel, the following vulnerability has been resolved: HID: bpf: Fix hid_bpf_get_data() range check hid_bpf_get_data() returns a pointer into the HID-BPF context data when the caller-provided offset and size fit inside ctx->allocated_size. The current check adds rdwr_buf_size and offset before comparing the result against ctx->allocated_size. Since both values are unsigned, a very large size can wrap the sum below ctx->allocated_size and make the helper return a pointer even thou

In the Linux kernel, the following vulnerability has been resolved: gue: validate REMCSUM private option length GUE private flags can indicate that remote checksum offload metadata is present. The private flags field itself is accounted for by guehdr_flags_len(), but guehdr_priv_flags_len() currently returns 0 even when GUE_PFLAG_REMCSUM is set. This lets a packet with only the private flags field pass validate_gue_flags(), after which gue_remcsum() and gue_gro_remcsum() read the missing REMC

In the Linux kernel, the following vulnerability has been resolved: netfilter: xt_u32: reject invalid shift counts u32_match_it() executes rule-supplied shift operands on a 32-bit value. A malformed u32 rule can provide a shift count of 32 or more, triggering an undefined shift out-of-bounds during packet evaluation. Validate XT_U32_LEFTSH and XT_U32_RIGHTSH operands in u32_mt_checkentry() and reject malformed rules before they reach the packet path.

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6tables: mark malformed IPv6 extension headers for hotdrop The ah, hbh and rt matches check that the fixed extension header is present, then use the header length field to derive the advertised extension header length for matching. For the ah match, add the missing advertised-length check. For hbh and rt, update the existing advertised-length checks. In all three cases, set hotdrop to true before returning false
