Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The perf mmap code does not prevent Virtual Memory Area VMA splits caused by resizing or partial unmapping of a mapping. This can lead to reference count leaks in perf mmap open and pe...

The vulnerability of the reference_count function and the biasPadEnable() function in the Linux operating system’s kernel allows a hacker to increase their privileges within the system.

The vulnerability of the referencecount biasPadEnable function in the Linux operating system is related to competitive access to resources a state of competition. Exploiting this vulnerability can allow a hacker to enhance their privileges within the system...

DEBIAN-CVE-2025-38349

In the Linux kernel, the following vulnerability has been resolved: eventpoll: don't decrement ep refcount while still holding the ep mutex Jann Horn points out that epoll is decrementing the ep refcount and then doing a mutexunlock&ep-mtx; afterwards. That's very wrong, because it can lead to a...

SUSE CVE-2025-52886

Poppler is a PDF rendering library. Versions prior to 25.06.0 use std::atomicint for reference counting. Because std::atomicint is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue...

Freedesktop Poppler 资源管理错误漏洞

Freedesktop Poppler is a Freedesktop community C++ class library for generating PDFs, which is inherited from Xpdf PDF reader. A resource management error vulnerability exists in Freedesktop Poppler versions prior to 25.06.0, which stems from a reference count overflow that could lead to reuse...

kernel: scsi: libfc: Fix use after free in fc_exch_abts_resp()

A vulnerability was found in the Linux kernel's SCSI libfc library in the fcexchabtsresp function, which can lead to a use-after-free scenario. This issue can occur because the function calls fcexchrelease, which decrements a reference count stored in the ep object and then frees the object once...
