PT-2026-38837

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in the function qtdemux parse theora extension within qtdemux.c. The vulnerability occurs due to an underflow of the gint size variable, which causes size to hold a large unintended...

PT-2026-38834

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in extract cc from data function within qtdemux.c. In the FOURCC c708 case, the subtraction atom length - 8 may result in an underflow if atom length is less than 8. When that...

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the ceph asynchronous unlink operation reducing the inlink counter prematurely before it is...

PT-2026-38833

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in qtdemux parse trak function within qtdemux.c. During the strf parsing case, the subtraction size -= 40 can lead to a negative integer overflow if it is less than 40. If this...

CROSS-implementation 安全漏洞

CROSS-implementation is an C-language implementation library for an asymmetric signature algorithm, developed by the CROSS Signature team. There is a security vulnerability in CROSS-implementation, which stems from a integer underflow in the cryptosignopen function, potentially leading to a buffe...
