expat: heap-based buffer over-read via crafted XML input

In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.

Open5GS through 2.8.0 Heap Out-of-Bounds Read via PFCP Dropped DL Traffic Threshold IE

Open5GS through 2.8.0 contains a heap out-of-bounds read vulnerability in ogs_pfcp_parse_dropped_dl_traffic_threshold() that allows remote unauthenticated attackers to read past IE buffers via short IEs. Attackers can send PFCP Session Establishment or Modification Requests to the UPF on UDP port 8805 with DLPA and DLBY flags set, potentially crashing the UPF.

CVE-2026-107738

SumatraPDF: Untrusted binary record offset used without lower-bound validation

SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, ChmFile::GetCharZ() narrows file-controlled unsigned string offsets from /#WINDOWS and /#IVB to signed integers without a lower-bound check. An offset that becomes negative can make the function read before the /#STRINGS buffer, causing deterministic application termination. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.

RIOT: Out-of-Bounds Read in RIOT OS 6LoWPAN SFF Fragment Handling

RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. In 2026.07 and earlier, _receive() in sys/net/gnrc/network_layer/sixlowpan/gnrc_sixlowpan.c can route an undersized packet into SFF fragment handling after only a minimal payload check. The code then interprets the packet as a sixlowpan_frag_t or larger fragment header without verifying that the packet snip contains the required bytes. A remote attacker can send a malformed 6LoWPAN fragment that causes gnrc_sixlowpan_frag_recv() to read beyond the packet buffer, potentially disclosing memory and crashing the network stack. No fixed repository release is available as of this review.

FreeRDP 2.0.0-beta1 before 3.28.0 Out-of-Bounds Read via LocateCardsByATRA Handler

FreeRDP from 2.0.0-beta1 before 3.28.0 contains an out-of-bounds read vulnerability in smartcard_LocateCardsByATRA_Call because the ATR pattern cbAtr byte count is not capped. Malicious RDP servers can send crafted ATR mask arrays to use query timing as an oracle, leaking heap memory bit-by-bit to defeat ASLR and aid RCE exploits.

FreeRDP 3.0.0 before 3.32.0 contains a heap out-of-bounds read in freerdp_assistance_parse_all_elements_of() because it advances its parsing cursor without reducing the remaining length, letting the scan window exceed the decrypted ConnectionString2 buffer. Attackers can supply a crafted .msrcIncident invitation file and password that crash xfreerdp when opened, before any RDP connection.
