GHSA-PHWJ-RPRQ-35PP Nokogiri: Possible Use-After-Free when setting an attribute value via `Nokogiri::XML::Attr#value=` or `#content=`

Summary Nokogiri’s CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, Nokogiri::XML::Attrvalue= could free the underlying native child node while the wrapper remained...

GHSA-WJV4-X9W8-WM3H Nokogiri: Possible Use-After-Free when setting `Document#root=` to an invalid node type

Summary Nokogiri::XML::Documentroot= validated only that the new root was a Nokogiri::XML::Node, allowing a DTD node to be set as the document root. The result is a heap use-after-free during garbage collection or finalization, leading to an invalid memory read or potentially a segfault. Nokogiri...

CVE-2026-56210

A heap-buffer-overflow read vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC Scalable Video Coding layer ID control function allows setting a spatiallayerid exceeding the configured number of layers. This causes an out-of-bounds heap rea...

Astra Linux – Vulnerability in RustC

In the standard library of Rust before version 1.29.0, there is weak synchronization in the Arc::getmut method. This synchronization issue can lead to memory safety issues due to race conditions...

Astra Linux – Vulnerability in RustC

In the standard library of Rust before version 1.2.0, BinaryHeap is not panic-safe. The binary heap becomes in an inconsistent state when the comparison of generic elements within siftup or siftdownrange causes a panic. This bug results in a decrease of zeroed memory of an arbitrary type, which c...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: crosectypec: Stale pointers have been set to zero. The function crostypecgetswitchhandles allocates four pointers when obtaining type-c switch handles. These pointers are all freed if none of them are obtained...

SUSE CVE-2026-6040

A heap use-after-free existed when importing the blank-width characters of an ODF number format. A position value read from the document was not checked against the length of the format-code string, so a malformed number format could be processed against memory outside that string. In fixed...
