CVE-2026-44251 1 Wazuh 1 Wazuh 2026-07-17 6.5 Medium
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.0.0 and above, prior to 4.14.5, a size_t integer underflow in os_crypto/shared/msgs.c:389 allows any enrolled Wazuh agent to crash the wazuh-remoted process on the manager, immediately disconnecting all agents from the manager. A second code path reached by the same underflow may allow heap memory corruption. This issue has been fixed in version 4.14.5.
CVE-2026-40106 1 Wazuh 1 Wazuh 2026-07-17 4.7 Medium
Wazuh is a free and open source platform used for threat prevention, detection, and response. Versions 4.6.0 and above prior to 4.14.5 contain a heap-based buffer overflow vulnerability in the syscheck component of the Wazuh agent for Windows. When expanding registry paths containing wildcards (* or ?), the agent allocates a fixed-size heap buffer of 256 bytes (OS_SIZE_256). By creating a registry subkey with a maximum allowed length (255 characters) inside a monitored path, a low-privileged local attacker can force an out-of-bounds write during string concatenation. Since wazuh-agent.exe runs as NT AUTHORITY\SYSTEM, this can lead to a silent Denial of Service (blinding the agent) or potentially Local Privilege Escalation (LPE). This issue has been fixed in version 4.14.5.
CVE-2026-50012 1 Squid-cache 1 Squid 2026-07-17 5.5 Medium
Squid is a caching proxy for the Web. Prior to 7.6, due to an improper input validation bug in cache digest reply handling (peerDigestSwapInMask in src/peer_digest.cc), Squid is vulnerable to a heap-based buffer overflow: a cache digest's on-the-wire size may be larger than the mask_size declared within the digest, so a trusted peer sending a maliciously crafted reply to a cache_digest request message can trigger the overflow. This attack is limited to Squid instances compiled with the --enable-cache-digests option and configured with cache_peer entries. This issue is fixed in version 7.6.
CVE-2026-15422 2026-07-17 N/A
The illumos SCTP inbound path performs association lookup for INIT ACK chunks without adequately validating the address parameters carried in the chunk. Since this lookup runs during packet classification (i.e. before SCTP integrity checks or IPsec policy are applied) a remote, unauthenticated attacker can send a crafted SCTP INIT ACK packet with malformed address parameters to cause an out-of-bounds access and kernel heap corruption, which may lead to remote code execution. The flaw has existed since 2010 (illumos-gate commit a5407c02), and affects any illumos distribution prior to illumos-gate commit 53a3efde.
CVE-2026-15449 2026-07-17 N/A
A time-of-check to time-of-use (TOCTOU) flaw in the illumos data-link pseudo-driver (dld) affects handling of the DLDIOC_GETMACPROP and DLDIOC_SETMACPROP ioctls on /dev/dld. drv_ioc_prop_common() in usr/src/uts/common/io/dld/dld_drv.c copies the dld_ioc_macprop_t ioctl header in once to read its pr_valsize field, sizes and allocates a kernel heap buffer from that value, and then copies the full request in a second time from the same unprivileged user address. A concurrent thread can enlarge pr_valsize between the two copyins, so the second copyin and the subsequent property handling write beyond the end of the undersized allocation and corrupt the kernel heap. An unprivileged local user, including one confined to a non-global zone that owns a datalink, can trigger this to panic the system. The resulting kernel heap corruption may be usable for further compromise.
CVE-2026-34150 1 Wazuh 1 Wazuh 2026-07-17 7.5 High
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 1.0.0 and above, prior to 4.14.5, a heap buffer overflow in wazuh-analysisd allows an unauthenticated remote attacker to crash the Wazuh manager's analysis engine, causing complete loss of SIEM alert processing. The attack exploits the default configuration shipped in the official wazuh/wazuh-docker deployment with default configuration. An attacker can enroll with authd without a password to obtain a valid agent ID and encryption key, connect to remoted over the Wazuh agent protocol, and inject rootcheck events containing  {key: value}  patterns longer than 30 bytes that trigger a sprintf overflow of a 30-byte buffer in W_JSON_ParseRootcheck, corrupting the heap and crashing wazuh-analysisd so that all alert processing silently stops while the dashboard and API keep showing stale data.
CVE-2026-28378 1 Grafana 2 Grafana, Grafana Enterprise 2026-07-17 3.1 Low
The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers.
CVE-2026-42533 1 F5 2 Nginx Open Source, Nginx Plus 2026-07-17 8.1 High
A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
