Base de CVEs

A flaw was found in GStreamer gst-plugins-good (avidemux). In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).

An out-of-bounds read issue in the Base64 decoder in Amazon aws-sdk-cpp before 1.11.862, on some platforms, might allow a remote authenticated user to crash an application that processes crafted Base64-encoded input. To remediate this issue, users should upgrade to version 1.11.862.

The Intel ALH digital-audio-interface driver function dai_alh_get_properties() in drivers/dai/intel/alh/alh.c used a caller-supplied int stream_id with no range validation. The value indexes the fixed-size static const uint8_t alh_handshake_map[64] array and scales a FIFO register address, so an out-of-range stream_id produces an out-of-bounds read of one byte at an attacker-chosen signed offset from the array. That byte is written into prop->dma_hs_id and the resulting struct dai_properties is copied back to the caller, leaking it. dai_get_properties_copy() is a Zephyr __syscall, and its verifier z_vrfy_dai_get_properties_copy() (drivers/dai/dai_handlers.c) validates only the device-object permission and the destination buffer, not stream_id. A user-mode thread that has been granted access to the ALH DAI device object can therefore call the syscall with an arbitrary stream_id, crossing the userspace/kernel sandbox boundary. The impact is a one-byte-per-call arbitrary-offset kernel information disclosure (and leakage of a computed kernel address via fifo_address); a stream_id that resolves to an unmapped page faults in kernel context, giving a local denial of service. Exploitation requires CONFIG_USERSPACE and device access, making this a local, moderate-severity issue. The fix rejects negative and too-large stream_id values up front and returns NULL, which the copy wrapper maps to -ENOENT.
