CVE-2026-32710 1 Mariadb 2 Mariadb, Server 2026-04-02 8.6 High
MariaDB server is a community developed fork of MySQL server. An authenticated user can crash MariaDB versions 11.4 before 11.4.10 and 11.8 before 11.8.6 via a bug in JSON_SCHEMA_VALID() function. Under certain conditions it might be possible to turn the crash into a remote code execution. These conditions require tight control over memory layout which is generally only attainable in a lab environment. This issue is fixed in MariaDB 11.4.10, MariaDB 11.8.6, and MariaDB 12.2.2.
CVE-2026-33986 1 Freerdp 1 Freerdp 2026-04-02 7.5 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in yuv_ensure_buffer() in libfreerdp/codec/h264.c, h264->width and h264->height are updated before the reallocation loop. If any winpr_aligned_recalloc() call fails, the function returns FALSE but width/height are already inflated. This issue has been patched in version 3.24.2.
CVE-2026-33987 1 Freerdp 1 Freerdp 2026-04-02 7.1 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in persistent_cache_read_entry_v3() in libfreerdp/cache/persistent.c, persistent->bmpSize is updated before winpr_aligned_recalloc(). If realloc fails, bmpSize is inflated while bmpData points to the old buffer. This issue has been patched in version 3.24.2.
CVE-2026-5185 1 Nothings 1 Stb Image 2026-04-01 5.3 Medium
A security flaw has been discovered in Nothings stb_image up to 2.30. This affects the function stbi__gif_load_next of the file stb_image.h of the component Multi-frame GIF File Handler. The manipulation results in heap-based buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-26073 2 Everest, Linuxfoundation 2 Everest-core, Everest 2026-03-31 5.9 Medium
EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to possible `std::queue`/`std::deque` corruption. The trigger is powermeter public key update and EV session/error events (while OCPP not started). This results in a TSAN data race report and an ASAN/UBSAN misaligned address runtime error being observed. Version 2026.02.0 contains a patch.
CVE-2025-14905 1 Redhat 12 Directory Server, Directory Server E4s, Directory Server Eus and 9 more 2026-03-31 7.2 High
A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).
CVE-2022-24450 3 Linuxfoundation, Nats, Redhat 3 Nats-server, Nats Streaming Server, Acm 2026-03-30 8.8 High
NATS nats-server before 2.7.2 has Incorrect Access Control. Any authenticated user can obtain the privileges of the System account by misusing the "dynamically provisioned sandbox accounts" feature.
CVE-2026-20408 2 Mediatek, Openwrt 8 Mt6890, Mt7615, Mt7915 and 5 more 2026-03-30 8.8 High
In wlan, there is a possible out of bounds write due to a heap buffer overflow. This could lead to remote (proximal/adjacent) escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00461651; Issue ID: MSV-4758.
CVE-2026-33249 2 Linuxfoundation, Nats 2 Nats-server, Nats Server 2026-03-27 4.3 Medium
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Starting in version 2.11.0 and prior to versions 2.11.15 and 2.12.6, a valid client which uses message tracing headers can indicate that the trace messages can be sent to an arbitrary valid subject, including those to which the client does not have publish permission. The payload is a valid trace message and not chosen by the attacker. Versions 2.11.15 and 2.12.6 contain a fix. No known workarounds are available.
CVE-2026-4395 1 Wolfssl 1 Wolfssl 2026-03-27 9.8 Critical
Heap-based buffer overflow in the KCAPI ECC code path of wc_ecc_import_x963_ex() in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkey_raw buffer via a crafted oversized EC public key point. The WOLFSSL_KCAPI_ECC code path copies the input to key->pubkey_raw (132 bytes) using XMEMCPY without a bounds check, unlike the ATECC code path which includes a length validation. This can be triggered during TLS key exchange when a malicious peer sends a crafted ECPoint in ServerKeyExchange.
CVE-2026-3229 1 Wolfssl 1 Wolfssl 2026-03-27 5.5 Medium
An integer overflow vulnerability existed in the static function wolfssl_add_to_chain, that caused heap corruption when certificate data was written out of bounds of an insufficiently sized certificate buffer. wolfssl_add_to_chain is called by these API: wolfSSL_CTX_add_extra_chain_cert, wolfSSL_CTX_add1_chain_cert, wolfSSL_add0_chain_cert. These API are enabled for 3rd party compatibility features: enable-opensslall, enable-opensslextra, enable-lighty, enable-stunnel, enable-nginx, enable-haproxy. This issue is not remotely exploitable, and would require that the application context loading certificates is compromised.
