CVE-2026-53189

A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...

CVE-2026-7531 Use-after-free in PQC hybrid key-share handling

Use-after-free in PQC hybrid key-share handling. This is an incomplete-fix follow-up to CVE-2026-5460 released in 5.9.1: a malicious TLS 1.3 server sending a truncated PQC hybrid KeyShare can still trigger the error cleanup path to operate on freed memory...

CVE-2026-57236

A flaw was found in Nokogiri, an XML and HTML library for Ruby. When an attacker provides an invalid encoding to the Documentencoding= function, the library frees the document's current encoding string without replacing it. This leaves the document referencing freed memory, which can lead to a...

Astra Linux – Vulnerability in libpng1.6

LIBPNG is a reference library used in applications that read, create, and manipulate PNG Portable Network Graphics raster image files. In versions 1.2.1 through 1.6.55, pngsettRNS and pngsetPLTE each act as aliases for a heap-allocated buffer between pngstruct and pnginfo. This buffer shares a...

libpng: libpng: Arbitrary code execution due to use-after-free vulnerability

A flaw was found in libpng, a library used for processing PNG Portable Network Graphics image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can...

ROS-20260623-73-0042

The vulnerability of the bytes.decode function in the CPython interpreter relates to the use of memory after it is freed. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the optsymbolkeysset. An attacker can cause the application to read from freed memory by toggling the symbolkeys option from true to false on a reused parser instance and then invoking the parse method. Remediation...

CVE-2026-48984 pam_usb: xfree() does not call explicit_bzero — sensitive cryptographic material may linger in freed heap

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, the xfree memory release helper in calls free without first zeroing the buffer contents, releasing heap-allocated buffers containing sensitive data — including one-time pad bytes read fr...

PT-2026-50769

Name of the Vulnerable Software and Affected Versions pam usb versions 0.9.1 and earlier Description The xfree memory release helper calls free without zeroing buffer contents first. This results in heap-allocated buffers containing sensitive data, such as one-time pad bytes read from disk, being...

The vulnerability of the Windows operating system’s kernel, which allows a hacker to increase their privileges

The vulnerability of Windows operating system kernels is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges...

EUVD-2026-36630

Software installed and run as a non-privileged user may conduct GPU system calls to write to arbitrary freed physical pages. Physical memory allocated and freed, without the deferred free mechanism can lead to those resources being used for read/write by the GPU after the kernel module has freed...

CVE-2026-41158

Summary of CVE-2026-41158: The vulnerability concerns GPU DDK where backed sparse PMRs are not handled by the deferred free mechanism after shrink, allowing a non-privileged user to perform GPU system calls that write to arbitrarily freed physical pages. The root cause is that physical memory all...

PT-2026-49023

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description Software installed and run as a non-privileged user may perform GPU system calls to write to arbitrary freed physical pages. This occurs because physical memory...

CVE-2026-46274

A flaw was found in the Linux kernel's input/output work queue io-wq component. This vulnerability occurs because the system incorrectly handles work queue entries, leading to a stale pointer. A local attacker could exploit this issue by manipulating work queue operations. Successful exploitation...

CVE-2026-8829

HTML::Entities versions before 3.84 for Perl read freed heap memory in decodeentities. The XS routine backing HTML::Entities::decodeentities cached a pointer repl into the entity-value SV returned by hvfetch on the entity2char hash. When the input SV was identical to a value SV in that hash, and...

Уязвимость инструмента удаленного администрирования Chromoting Chrome Remote Desktop браузеров Google Chrome и Microsoft Edge связана с возможностью использования памяти после освобождения. Эксплуатация уязвимости может позволить нарушителю, действующему удаленно, выполнить произвольный код...

Linux kernel 安全漏洞

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 accidental reuse of freed memory due to an unexpected GFN in KVM x86 shadow paging...

CVE-2026-45984

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

CVE-2026-43497

A flaw was found in the Linux kernel's udlfb driver. This use-after-free vulnerability occurs because the dlfbopsmmap function does not properly track active memory mappings. When the framebuffer is reallocated, existing memory page table entries PTEs are not invalidated. This allows a local...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Added NULL checks when resetting request and reply queues. The driver encountered a crash during resource cleanup when the reply and request queues were NULL due to freed memory. This issue occurred when the creatio...
