CVE-2026-69249

A flaw was found in python-cryptography. When processing invalid certificate chains that include duplicate self-signed certificates, the system recursively invokes the same certificate, leading to an exponential increase in processing time. A remote attacker could exploit this by providing a...

CVE-2026-75159 MongoDB BI Connector Improper Memory Handling During Failed Kerberos Authentication May Cause Process Termination

An unauthenticated client that can reach a MongoDB Connector for BI deployment configured with Kerberos authentication may cause mongosqld to terminate when a crafted authentication exchange encounters a specific GSSAPI error-handling condition. This can interrupt BI Connector availability until...

CVE-2026-75159

CVE-2026-75159 affects MongoDB Connector for BI (mongosqld) deployments configured with Kerberos authentication . An unauthenticated, network-reachable client can trigger a specific GSSAPI error-handling condition during a crafted authentication exchange, causing mongosqld to terminate. This inte...

CVE-2026-67353

A flaw was found in guzzlehttp/guzzle. A remote attacker can exploit this vulnerability by sending an excessive number of large 'Set-Cookie' header fields from a malicious server. This causes the application's CookieJar to store an unbounded amount of data in memory, leading to resource exhaustio...

A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript replace function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory...

CVE-2026-71402 wicked: out-of-bounds read in the DHCPv4 option parser due to payload length taken from the IP total length

An out-of-bounds read was found in the DHCPv4 packet capture code of wicked. nicaptureinspectudpheader in src/capture.c reports the IP total length as the payload length instead of the length of the remaining UDP payload. Consequently, the DHCP option walker in the DHCPv4 client wickedd-dhcp4 rea...

CVE-2026-71402

CVE-2026-71402 is an out-of-bounds read in the DHCPv4 packet capture code of wicked (the openSUSE/SUSE network daemon), specifically in ni_capture_inspect_udp_header() in src/capture.c. The function reports the IP total length as the payload length instead of the remaining UDP payload length, cau...

CVE-2026-80588

A flaw was found in the Linux kernel's Multipath TCP mptcp implementation. Errors occurring during the receive path, before data is queued, may prevent the system from reclaiming forward-allocated memory. This can lead to an unbounded increase in memory usage under certain network conditions, suc...

CVE-2026-80552

A flaw was found in the s390/vfioccw component of the Linux kernel. This vulnerability occurs because the system fails to properly validate index ranges for read/write operations on existing regions. This oversight could allow an attacker to perform out-of-bounds memory access, potentially leadin...

CVE-2026-71401

An integer underflow in the wicked DHCPv4 packet capture code (function ni_capture_inspect_udp_header() in src/capture.c) allows an unauthenticated attacker on an adjacent network to trigger an out-of-bounds read past the receive buffer in the wickedd-dhcp4 daemon. The IP total length field is no...
