GPAC through 26.07.0 NULL Pointer Dereference via MPEG-4 Form Handlers

GPAC through 26.07.0 contains a NULL pointer dereference vulnerability in the MPEG-4 Form spatial-constraint handlers in src/compositor/mpeg4_form.c that lets attackers crash the process via unchecked group lookups. Attackers can supply a crafted XMT scene whose Form constraints reference a non-existent group, crashing tools like MP4Box during chapter import for denial of service.

Node.js is vulnerable to a remotely triggerable uncaught exception in TLS servers via deferred handshake callbacks

A deferred-callback use-after-destroy in Node.js TLS server handshake handling allows a remote, unauthenticated attacker to terminate the server process. When a TLS server uses any of the SNICallback, OCSPRequest, newSession, or resumeSession hooks, or server.addContext(), the corresponding OpenSSL callbacks are deferred, and the deferred code does not handle the underlying socket being destroyed between scheduling and execution. By sending a client hello that reaches the vulnerable path (for example, no SNI together with an OCSP request) followed by padding and a socket FIN, an attacker makes OpenSSL deliver the client hello and the end-of-file in the same tick, so the socket is destroyed before the deferred callback runs and the process raises an uncaught exception instead of emitting an 'error' event. This vulnerability affects Node.js 26.x and 24.x.

Sssd: sssd: local denial of service through unchecked oauth2 json code type in pam responder

A flaw was found in SSSD's PAM responder on builds with the JSON PAM extension enabled. A local attacker can submit a crafted authentication request containing a non-string OAuth2 code value. Missing JSON type validation leads to a NULL pointer dereference, terminating the PAM responder and disrupting SSSD-backed authentication.

Pre-authentication NULL pointer dereference in MCUboot serial-recovery image upload (encrypted-image builds)

MCUboot's serial-recovery image-upload handler bs_upload() in boot/boot_serial/src/boot_serial.c declares const struct flash_area *fap = NULL and assigns it only via flash_area_open() part-way through the function. Two early validation failures (goto out_invalid_data) — a CBOR map that fails to decode, or an upload packet missing the off/data members — branch past the open while fap is still NULL, then fall into the shared epilogue. In MCUBOOT_ENC_IMAGES builds that epilogue unconditionally calls boot_handle_enc_fw(fap), which reaches boot_image_load_header() and flash_area_read() and dereferences the NULL flash_area. The defect is reachable pre-authentication: the trigger is the very first serial-recovery upload command carrying a malformed payload. The guarding conditions are default-true on a fresh recovery session — img_num, curr_off and img_size are zero-initialized statics, so curr_off == img_size and the primary-slot test both hold. It requires a non-default build: encrypted images (MCUBOOT_ENC_IMAGES / Zephyr CONFIG_BOOT_ENCRYPT_IMAGE) together with an active serial-recovery transport, on the Zephyr or Mynewt port (the two that build both boot/boot_serial/src/boot_serial.c and boot_serial_encryption.c with MCUBOOT_ENC_IMAGES). The impact is a transient denial of service of the bootloader during recovery. fap is a hard NULL rather than an attacker-controlled value, so there is no memory-corruption or information-leak primitive and image authentication is unaffected. Whether the dereference faults is platform-dependent — on targets where address 0x0 is mapped readable flash the read merely returns an error and execution continues, while targets that trap NULL (MPU / null-pointer-exception detection) take a hard fault. Because serial recovery is unauthenticated by design and already permits the console attacker to write the secondary slot, the added capability is only a low-value transient crash. The related unconditional flash_area_close(fap) call in the same epilogue is a safe no-op on the ports that reach it, so it does not contribute to the dereference. The affected ports are the Zephyr port — boot/zephyr/CMakeLists.txt compiles boot_serial.c under CONFIG_MCUBOOT_SERIAL and boot_serial_encryption.c under CONFIG_BOOT_ENCRYPT_IMAGE — and the Mynewt port, whose mcuboot_config.h defines MCUBOOT_SERIAL unconditionally and MCUBOOT_ENC_IMAGES under any BOOTUTIL_ENCRYPT_ syscfg, with boot/boot_serial/pkg.yml declaring no explicit source list so the whole directory is built. The Espressif port is not affected**: it compiles boot_serial.c but not boot_serial_encryption.c, and defines no MCUBOOT_ENC_IMAGES, so the #ifdef MCUBOOT_ENC_IMAGES block containing the call is preprocessed away. The NuttX, Cypress and Mbed ports do not build boot_serial.c at all.

Forge: TLS client crash on a handshake record received without a session

Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.3, a forge.tls client can pass a handshake record to tls.handleHandshake() while the connection has no session, including after a close_notify alert, after the application calls close(), or before handshake() is called. The handler dereferences c.session.md5 before dispatching the message, causing a TypeError to propagate from connection.process(). A malicious server or on-path attacker can deliver the record, including after a reset when the connection uses no encryption, and terminate a Node.js process if the application does not catch the exception. forge.tls servers are not affected, and there is no confidentiality or integrity impact. This issue is fixed in version 1.4.3.

ACPI: NFIT: core: Fix possible NULL pointer dereference

In the Linux kernel, the following vulnerability has been resolved: ACPI: NFIT: core: Fix possible NULL pointer dereference After commit 9b311b7313d6 ("ACPI: NFIT: Install Notify() handler before getting NFIT table"), acpi_nfit_probe() installs an ACPI notify handler for the NFIT device before checking the presence of the NFIT table. If that table is not there, 0 is returned without allocating the acpi_desc object and setting the driver data pointer of the NFIT device. If the platform firmware triggers an NFIT_NOTIFY_UC_MEMORY_ERROR notification on the NFIT device at that point, acpi_nfit_uc_error_notify() will dereference a NULL pointer. Prevent that from occurring by adding an acpi_desc check against NULL to acpi_nfit_uc_error_notify().

Node.js is vulnerable to an HTTP/2 denial of service via a NULL pointer dereference when a respondWithFile() download is cancelled

A NULL pointer dereference in Node.js HTTP/2 lets an unauthenticated client crash the server, over both TLS and cleartext, by cancelling file downloads. When the server serves a file with stream.respondWithFile() or stream.respondWithFD() and the client cancels the request, a StreamPipe used for the transfer is torn down in an order that leaves a NULL pointer which is then dereferenced, aborting the process. No crafted frames are needed, and a handful of cancelled requests against a default file-serving handler is enough. This vulnerability affects Node.js 26.x, 24.x, and 22.x.

virtio_pci: fix vq info pointer lookup via wrong index

In the Linux kernel, the following vulnerability has been resolved: virtio_pci: fix vq info pointer lookup via wrong index Unbinding a virtio balloon device: echo virtio0 > /sys/bus/virtio/drivers/virtio_balloon/unbind triggers a NULL pointer dereference. The dmesg says: BUG: kernel NULL pointer dereference, address: 0000000000000008 [...] RIP: 0010:__list_del_entry_valid_or_report+0x5/0xf0 Call Trace: <TASK> vp_del_vqs+0x121/0x230 remove_common+0x135/0x150 virtballoon_remove+0xee/0x100 virtio_dev_remove+0x3b/0x80 device_release_driver_internal+0x187/0x2c0 unbind_store+0xb9/0xe0 kernfs_fop_write_iter.llvm.11660790530567441834+0xf6/0x180 vfs_write+0x2a9/0x3b0 ksys_write+0x5c/0xd0 do_syscall_64+0x54/0x230 entry_SYSCALL_64_after_hwframe+0x29/0x31 [...] </TASK> The virtio_balloon device registers 5 queues (inflate, deflate, stats, free_page, reporting) but only the first two are unconditional. The stats, free_page and reporting queues are each conditional on their respective feature bits. When any of these features are absent, the corresponding vqs_info entry has name == NULL, creating holes in the array. The root cause is an indexing mismatch introduced when vq info storage was changed to be passed as an argument. vp_find_vqs_msix() and vp_find_vqs_intx() store the info pointer at vp_dev->vqs[i], where 'i' is the caller's sparse array index. However, the virtqueue itself gets vq->index assigned from queue_idx, a dense index that skips NULL entries. When holes exist, 'i' and queue_idx diverge. Later, vp_del_vqs() looks up info via vp_dev->vqs[vq->index] using the dense index into the sparsely-populated array, and hits NULL. Fix this by storing info at vp_dev->vqs[queue_idx] instead of vp_dev->vqs[i], so the store index matches the lookup index (vq->index). Apply the fix to both the MSIX and INTX paths.

In the Linux kernel, the following vulnerability has been resolved: ALSA: ice1712: check snd_ctl_new1() return value snd_ctl_new1() can return NULL when memory allocation fails. The ice1712 driver calls snd_ctl_new1() without checking the return value before dereferencing the pointer in multiple places (ice1712.c, ice1724.c, aureon.c), which can lead to NULL pointer dereferences. Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any fails.

dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work

In the Linux kernel, the following vulnerability has been resolved: dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work The change_work was introduced to send device change notifications from DPLL device callbacks without deadlocking on dpll_lock, since the callbacks are already invoked under that lock. Now that __dpll_device_change_ntf() is exported for callers that already hold dpll_lock, use it directly and remove the change_work infrastructure entirely. This eliminates a race condition where change_work could be re-scheduled after cancel_work_sync() during device teardown, potentially causing the handler to dereference a freed or NULL dpll_dev pointer.
