CVE-2026-89126
SAP Web Dispatcher does not sufficiently validate certain network input processed by an internal component. An unauthenticated attacker could send specially crafted network traffic to trigger a memory corruption condition in the affected functionality. Successful exploitation could allow the attacker to execute arbitrary code and fully compromise the system, resulting in a high impact on confidentiality, integrity and availability of the system.

-
CVE-2026-126912
Buffer overflow in Skia in Google Chrome prior to 157.0.8103.78 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
-
CVE-2026-126885

-
CVE-2026-118383
A use-after-free in the replication component of MongoDB Server can occur when a newly elected replica set primary completes catch-up. The condition can be caused by requests that do not require authentication, and may result in the server terminating unexpectedly or, under certain conditions, arbitrary code execution in the context of the server process. Replica set members are affected, including the shard and config server replica set members of sharded clusters; standalone mongod instances are not.
-
CVE-2026-120868
Memory overflow in Packet Processing can lead to unpredictable or erroneous behavior or Denial of Service in NetScaler ADC and NetScaler Gateway.
-
CVE-2026-121289
On affected platforms running Arista EOS with BGP configured, a specially crafted packet can cause the BGP agent to crash. Successful exploitation causes the BGP agent process to terminate, resulting in the loss of all BGP sessions on the affected device and possible disruption to network routing until the process recovers. Due to the nature of the vulnerability, it may also be possible for a sophisticated attacker to achieve arbitrary code execution, which could compromise the confidentiality and integrity of the affected system.
-
CVE-2026-113364
Buffer Overflow in the data receiving process in NEC Corporation WebSAM WinShare Ver 7.5.0 and earlier, Ver 7.6.0 and Ver 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary code with SYSTEM privileges via a crafted packet with a malformed data size value in the protocol header.
-
CVE-2026-123966
A vulnerability was determined in Tenda AC19 16.03.10.07. Affected by this issue is the function saveParentControlInfo of the file /goform/saveParentControlInfo. This manipulation of the argument deviceId causes heap-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.
-
CVE-2026-95962
Use after free in Windows Virtual Filtering Platform (VFP) allows an unauthorized attacker to execute code over a network.
-
CVE-2026-124040
CivetWeb through 1.16, when built with USE_HTTP2 and enable_http2 on, contains a use-after-free vulnerability in handle_http2() that retains freed :method and :path pointers. Unauthenticated remote attackers can send a later HEADERS frame omitting these pseudo-headers to influence request method or path seen by access rules, or crash the server.
Critical CVEs are vulnerabilities scored 9.0 or higher on the CVSS scale. This list shows the ones with no patch or vendor advisory linked yet, ranked by how likely they are to be exploited (EPSS).
