CVE-2026-472578.1 ALT—
———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. In versions 1.5.0 and 1.6.0-rc1, there is a restore logic flaw in bacnet-stack that is reachable through the official, unmodified apps/server management path when BACNET_BACKUP_RESTORE is enabled. This issue has been patched in versions 1.5.1 and 1.6.0.4hCVE-2026-472177.5 ALT—
———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4 and 1.5.1, a remote attacker can trigger an uncontrolled recursion and stack overflow in the default server application of bacnet-stack by abusing the Channel object. This issue has been patched in versions 1.4.4 and 1.5.1.4hCVE-2026-1269038.1 ALT—
——0Improper state validation in ANGLE in Google Chrome on on Windows prior to 157.0.8103.78 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: High)7hCVE-2026-40670—4.2%
——1Improper check for unusual or exceptional conditions in AMD Secure Encrypted Virtualization - Secure Nested Paging (SEV-SNP) could allow a privileged attacker to potentially overlap MMIO regions with DRAM regions resulting in loss of integrity.2hCVE-2026-1208076.6 MÉD13.6%
——4A flaw in MongoDB’s X.509 cluster-membership authentication guard could allow a holder of a cluster-member certificate to gain elevated internal privileges when a specific deployment configuration is in use. An internal check, which prevents a certificate recognized as a cluster member from also being treated as a regular user, does not correctly distinguish between certain error conditions encountered during user lookup. Under certain timing conditions, this can cause the check to be bypassed, granting the connection full internal system privileges. Triggering this issue requires possession of a valid cluster-member TLS certificate, non-default X.509 cluster authentication configuration, and specific conditions during the user cache lookup process.2dCVE-2026-1235887.5 ALT28.2%
——8The recursive resolver in Hickory DNS (all versions of the hickory-recursor crate, and hickory-resolver 0.26.0 before 0.26.2) caches an empty connection pool when it follows a referral with no glue records and all queries for the name servers' IP addresses fail. An attacker able to spoof DNS responses can make these lookups fail, causing all subsequent queries for the affected zone to fail until the cache entry expires or is evicted.12h
