Memory-safety defects in the upstream (abandoned) AOSP OpenCORE AAC decoder, shipped unpatched by Samsung TizenRT

Abandoned AOSP OpenCORE AAC decoder has out-of-bounds-write and wild-pointer flaws reachable from attacker-controlled frames, unpatched in Samsung TizenRT.

The OpenCORE AAC decoder in AOSP's abandoned external/opencore tree contains memory-safety defects of the out-of-bounds-write and wild-pointer class. The code is still vendored and built by multiple projects, most notably Samsung's widely deployed TizenRT embedded RTOS. The defects are reachable from untrusted media because an AAC frame is attacker-controlled. The researcher is requesting a CVE ID for the issue.

VLC Media Player Flaws Let Attackers Corrupt Memory and Leak Sensitive Data

VLC 3.0.0-3.0.23 has two flaws: a heap out-of-bounds write via malicious PNGs (CVE-2026-56711) and an out-of-bounds read via hostile RealRTSP servers.

CVE-2026-56711 is a heap out-of-bounds write (CVSS v4 8.6) caused by an integer overflow in VLC's AllocatePicture routine when processing PNG images with exceptionally large IHDR width and height values, allowing writes past the allocated buffer; it maps to CWE-190 and CWE-787 and was credited to Fabian Wahle of Hap Security. CVE-2026-73324 is a medium-severity out-of-bounds read (CVSS v4 6.9) in VLC's RealRTSP handling, where RtspReadLine copies response lines longer than 4,096 bytes into a fixed buffer without null termination, potentially leaking heap data back to a hostile RTSP server via the Session header. Both bugs affect VLC 3.0.0 through 3.0.23, and updated builds had not yet been released at the time of disclosure.
