CVE-2026-45329 ESF-IDF: Out-of-Bounds Read in ESP-TEE Secure Service Wrappers

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.5.4 and 6.0, several ESP-TEE secure-service wrappers in espsecureservices.c and espsecureservicesiram.c validated only some of the caller-supplied pointer arguments, leaving input pointer arguments unchecked...

CVE-2026-45328

The CVE concerns ESF-IDF’s ESP-IDF esp_tee component. In versions 5.5.4 and 6.0, the secure-service wrappers in esp_secure_services.c and esp_secure_services_iram.c bridge calls from the REE to TEE-protected peripherals (AES, SHA, ECC, HMAC, SPI, MMU, WDT) and security features (attestation, OTA,...

CVE-2026-45160 ESF-IDF: Out-of-bounds Read in lwIP DHCP Server Option Parser

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.2.7, 5.3.5, 5.4.4, 5.5.4, and 6.0.1, an out-of-bounds read flaw exists in the DHCP server option parser parseoptions in components/lwip/apps/dhcpserver/dhcpserver.c shipped with ESP-IDF's lwIP component. The pars...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...
