CVE-2026-70368 Stunnel: stack-based out-of-bounds read/write in stunnel s_vlog via oversized log message

A stack-based out-of-bounds read vulnerability exists in the "svlog" function of stunnel, when handling oversized log messages via "vsnprintf". A remote attacker with network access to a stunnel service can send protocol inputs that trigger a log message longer than 1024 bytes, leading to an...

AZL-93461 CVE-2026-64411 affecting package kernel for versions less than 6.6.145.2-1

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: terminate table name before findtablelock updatecounters and compatupdatecounters forward a user-supplied 32-byte table name to findtablelock without NUL-terminating it. On a lookup miss, findinlistlock calls...

capstone: Capstone: Memory corruption via unchecked vsnprintf return

A flaw was found in Capstone, a disassembly framework. An unchecked return value from vsnprintf within the SStreamconcat function allows a malicious input to manipulate the internal stream index. This can lead to a stack buffer underflow or overflow, potentially enabling a local attacker to achie...

Medium: capstone

Issue Overview: Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStreamconcat lets a malicious csoptmem.vsnprintf drive SStream's index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Comm...
