Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fixes:...

CVE-2026-57437

A flaw was found in Nokogiri, an XML and HTML library for Ruby. This vulnerability occurs when an application directly constructs an XPathContext and allows its associated document to be garbage collected while the context is still in use. An attacker could potentially exploit this by causing the...

SUSE CVE-2026-52995

In the Linux kernel, the following vulnerability has been resolved: net/rds: zero per-item info buffer before handing it to visitors rdsforeachconninfo and rdswalkconnpathinfo both hand a caller-allocated on-stack u64 buffer to a per-connection visitor and then copy the full itemlen bytes back to...

SUSE CVE-2026-53005

In the Linux kernel, the following vulnerability has been resolved: afunix: Drop all SCM attributes for SOCKMAP. SOCKMAP can hide inflight fd from AFUNIX GC. When a socket in SOCKMAP receives skb with inflight fd, skpsockverdictdataready looks up the mapped socket and enqueue skb to its...

SUSE CVE-2026-53018

In the Linux kernel, the following vulnerability has been resolved: f2fs: avoid reading already updated pages during GC We found the following issue during fuzz testing: page: refcount:3 mapcount:0 mapping:00000000b6e89c65 index:0x18b2dc pfn:0x161ba9 memcg:f8ffff800e269c00 aops:f2fsmetaaops ino:2...

GHSA-QPW4-5X99-6VJP golang.org/x/crypto: Invoking memory leak when rejecting channels can lead to DoS

An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected users. Rejected channels are now properly removed from the connection's internal state and released for...

CVE-2026-53018

A flaw was found in the Linux kernel's f2fs filesystem. During garbage collection, a race condition can occur when a page is moved and updated, but the system attempts to read it again from an outdated location. This can trigger a kernel bug, leading to a system crash and a denial of service DoS....

CVE-2026-57437

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::XPathContext did not keep its source document alive for garbage collection. If an XPathContext outlived its document and the document was collected, evaluating an XPath expression...

CVE-2026-57437 Nokogiri: Possible Use-After-Free when directly using `NokogirI::XML::XPathContext` beyond document lifetime

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::XPathContext did not keep its source document alive for garbage collection. If an XPathContext outlived its document and the document was collected, evaluating an XPath expression...

CVE-2026-57436 Nokogiri: Possible Use-After-Free when setting `Document#root=` to an invalid node type

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, 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...

CVE-2026-57435 Nokogiri: Possible Use-After-Free when setting an attribute value via `Nokogiri::XML::Attr#value=` or `#content=`

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, 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,...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...
