CVE-2026-80542

A flaw was found in the drm/amd/display component of the Linux kernel. The amdgpudmcrtcsetvblank function attempts to dereference a NULL pointer when vblank is enabled or queried before a display stream is properly attached. This can be triggered by a local attacker running specific graphics test...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-80519

A flaw was found in the Linux kernel. Specifically, within the OpenVPN OVPN module's crypto completion callback mechanism, a timing issue exists. This vulnerability arises when peer references are released prematurely, before the associated cleanup operations are complete. An attacker could...

CVE-2026-67590

A flaw was found in Apache Qpid ProtonJ2. A remote attacker, without needing to authenticate, could exploit a vulnerability related to unbounded type nesting. This could lead to a StackOverflowError, causing the application to become unresponsive and resulting in a denial of service...

CVE-2026-67552

A flaw was found in Apache Qpid Proton-Dotnet. This vulnerability allows a remote attacker, without needing to authenticate, to exploit a weakness in how the software handles data structures with excessive nesting. This can lead to a StackOverflowError, which ultimately results in a denial of...

CVE-2026-67551

A flaw was found in Apache Qpid Proton Dotnet. A remote, unauthenticated attacker could exploit a vulnerability in the handling of type sizes and counts. This could lead to excessive memory allocation, resulting in a denial of service DoS for the affected system...

CVE-2026-80568

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. Changing the diagnostic report type while a video stream V4L2 is active can alter the expected report size. Since V4L2 buffers are allocated based on the initial size at stream start, a larger subsequent report could lead to a he...

CVE-2026-63388

A flaw was found in Libevent. A heap out-of-bounds write vulnerability in the buffereventsocketsetconnaddress function allows an unauthenticated local peer to achieve arbitrary code execution. By connecting to an AFUNIX listener, an attacker can overwrite critical heap data, leading to memory...

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-80564

A flaw was found in the Linux kernel's gve component. A local user can trigger a NULL pointer dereference by attempting to use the ptp adjfine function, which has a missing implementation. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-63380

A flaw was found in Libevent, an event notification library. This vulnerability allows a local attacker to trigger a null pointer dereference during specific error handling within the evwsnewsession function. By inducing an allocation or locking failure, an attacker can cause the application to...

CVE-2026-42931

A flaw was found in Gitea. An authenticated attacker can trigger a denial of service by sending a large HTTP request to the NPM package tag API endpoint. The server attempts to read the entire request body into memory without a size limit, leading to an Out-of-Memory OOM error and crashing the...

CVE-2026-63387

A flaw was found in Libevent, an event notification library. An off-by-one stack buffer overflow exists in the dnsnametolabels function when processing a name-bearing DNS record. A remote attacker could send a specially crafted DNS server response, which may lead to a crash or corruption of the...

CVE-2026-63495

A flaw was found in Libevent. An unauthenticated remote client can exploit this vulnerability by repeatedly sending fragmented WebSocket frames to the Libevent WebSocket server. Due to a lack of a total message-size limit, these fragmented frames accumulate in memory without bound, leading to...

CVE-2026-63384

A flaw was found in Libevent. An incorrect integer conversion in the evtagunmarshalheader function allows a remote attacker to provide a specially crafted payload length. This can lead to a wrapped large allocation request, resulting in a denial of service DoS for the affected system...

CVE-2026-63383

A flaw was found in Libevent, an event notification library. A remote attacker could exploit an out-of-bounds read vulnerability in the decodetaginternal function by sending specially crafted, attacker-controlled tagged RPC Remote Procedure Call data. This could lead to a denial of service, causi...

CVE-2026-80540

A flaw was found in the Linux kernel's drm/amdgpu component, specifically within the Universal Video Decoder UVD image size calculation. This vulnerability occurs because the minimum image size calculation incorrectly uses width instead of pitch and fails to reject pitch values exceeding 4096. An...

CVE-2026-71084

A flaw was found in mysql-connector-odbc. An unauthenticated attacker with local logon access to the infrastructure where MySQL Connectors executes can exploit this vulnerability. This can lead to a complete denial of service DoS by causing the component to crash repeatedly. Additionally, the...

CVE-2026-71079

A flaw was found in MySQL Connector/ODBC. This vulnerability allows a low privileged attacker with network access to cause a complete denial of service DoS by triggering a hang or frequently repeatable crash of the component. The attacker can exploit this flaw through multiple protocols...
