CVE-2025-68775 net/handshake: duplicate handshake cancellations leak socket

In the Linux kernel, the following vulnerability has been resolved: net/handshake: duplicate handshake cancellations leak socket When a handshake request is cancelled it is removed from the handshakenet-hnrequests list, but it is still present in the handshakerhashtbl until it is destroyed. If a...

CVE-2025-68775

CVE-2025-68775 affects the Linux kernel’s net/handshake code. A duplicate handshake cancellation can leave the handshake entry in the rhashtbl and, if a second cancellation occurs without HANDSHAKE_F_REQ_COMPLETED being set, lead to a refcount underflow on the socket. The issue arises when a canc...

curl: MQTT: unsigned integer underflow bypasses MAX_MQTT_MESSAGE_SIZE check

Summary An unsigned integer underflow exists in libcurl's MQTT publish path. Due to incorrect arithmetic ordering in the size validation logic, oversized MQTT PUBLISH messages are not rejected as intended. Affected version libcurl 8.18.0 Tested on macOS arm64 with AddressSanitizer enabled. Steps ...

Astra Linux – Vulnerability in StrongSwan

In the eap-mschapv2 plugin client-side in strongSwan, prior to version 6.0.3, a malicious EAP-MSCHAPv2 server could send a crafted message with a size of 6 to 8 bytes, causing an integer underflow, which could potentially lead to a heap-based buffer overflow...

curl: integer Overflow in MQTT Protocol Handling Allows Bypassing Message Size Limit

Summary: A logic error involving an integer overflow specifically, an unsigned integer underflow exists in the lib/mqtt.c file within the mqttpublish function. This vulnerability allows an attacker or a malicious user configuration to bypass the explicit MAXMQTTMESSAGESIZE check. The vulnerabilit...

curl: Integer-underflow leads to heap over-read in TFTP implementation

libcurl on commit 3ee1d3b573e6ea36fb478dbd0d9913483b900928 contains a vulnerability in its TFTP implementation that can cause curl or a libcurl-user to send heap memory beyond the bounds of an allocated chunk to a malicious TFTP server. The vulnerability lies in lib/tftp.c, in function...
