Out-of-bounds Read in OpenCV

An out-of-bounds read was discovered in OpenCV before 4.1.1 OpenCV-Python before 4.1.0.25. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this is not true when dealing with small images, leading...

PYSEC-2026-2805 Out-of-bounds Read in OpenCV

OpenCV Open Source Computer Vision Library through 3.3 corresponding to OpenCV-Python 3.3.0.9 has an out-of-bounds read error in the cv::RBaseStream::readBlock function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by using cv::imread, as demonstrated by the...

CVE-2026-10659

The CVE concerns Zephyr’s Dhara FTL disk driver (drivers/disk/ftl_dhara.c). On flash read errors, the driver previously wrote error codes unconditionally to a caller-supplied err pointer, and the journal-resume path forwarded NULL into dhara_nand_read(), causing a NULL dereference during disk ini...

CVE-2026-10659 NULL pointer dereference in Zephyr Dhara FTL disk driver on flash read error during journal resume

The Dhara flash translation layer disk driver drivers/disk/ftldhara.c implemented the dharanand callbacks so that, on a flash error, the error code was written unconditionally through the caller-supplied dharaerrort err pointer e.g. err = DHARAEECC in dharanandread, and similar in...

CVE-2026-56015

Net::IP::LPM versions through 1.10 for Perl allow a heap out-of-bounds read via an unbounded prefix length. add passes the prefix string to the trie builder addPrefixToTrie without checking it against the address width. addPrefixToTrie then walks the prefix buffer by prefixlength bits, reading...

EUVD-2026-40313

A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the gdatetimegetymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the gdatetimeaddfull function is processed. This flaw can corrupt the date output and potentially cause logic errors...

CVE-2026-53165

A flaw was found in the Linux kernel's iomap subsystem. A race condition can occur during buffered read error reporting, specifically in the iomapfinishfolioread function. This allows a separate process to clear a folio's mapping while an error is being reported, leading to a null pointer...

UBUNTU-CVE-2026-12340

Out-of-bounds heap read during SM2/SM3 certificate signature verification. When parsing a certificate with an SM3wSM2 signature, the Subject Key Identifier computation reads the trailing 65 bytes of the public key without checking that the key is at least that long. A public key shorter than 65...

httpd: mod_proxy_ajp: off-by-one out-of-bounds reads in AJP getter functions

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the AJP getter functions attempt to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause an out-of-bounds read. This issue leads to a denial of...

CVE-2026-54412 MQTT-C Heap Out-of-Bounds Read and Integer Underflow in mqtt_unpack_publish_response()

LiamBindle MQTT-C through version 1.1.6 contains a heap-based out-of-bounds read and integer underflow in the mqttunpackpublishresponse function in src/mqtt.c that allows a remote unauthenticated attacker controlling an MQTT broker - or able to inject MQTT traffic into an unencrypted session - to...

CVE-2026-46532 ESF-IDF: Heap Out-of-Bounds Read in Bluedroid AVRCP Target Parser

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.2.6, 5.3.5, 5.4.4, 5.5.3, and 6.0, an out-of-bounds read exists in the BlueDroid AVRCP vendor-command parser avrcparsvendorcmd in components/bt/host/bluedroid/stack/avrc/avrcparstg.c. This issue has been patched ...

CVE-2026-46433

CVE-2026-46433 affects lldpd (LLDP implementation). Prior to version 1.0.22, lldpd_decode() incorrectly shifts frame payload when removing 802.1Q VLAN tags, using a length calculation that causes a 4-byte heap OOB read if the frame size equals the interface MTU. This vulnerability is fixed in ver...
