CVE-2026-111759 markdown-it: Quadratic complexity in smartquotes with unmatched closing quotes

markdown-it is a Markdown parser. Prior to 14.3.2 and 15.0.2, when typographer: true is enabled, specially crafted Markdown can cause quadratic processing time in the smartquotes rule, potentially leading to denial of service in applications processing untrusted input. Many opening double quotes...

CVE-2026-98538 writeback: bound cleanup_offline_cgwb() rescans by rotating scanned inodes

In the Linux kernel, the following vulnerability has been resolved: writeback: bound cleanupofflinecgwb rescans by rotating scanned inodes cleanupofflinecgwb prepares at most WBMAXINODESPERISW inodes per call and is called again until the dying wb is drained, but every call walks wb-battached and...

CVE-2026-98538

The Linux kernel contains a performance issue in the writeback subsystem where the cleanup_offline_cgwb() function performs a quadratic drain of inodes. This occurs because the function repeatedly walks wb->b_attached and wb->b_dirty_time from the same end, causing it to rescanned a growing...

CVE-2026-110872 Nodemailer 3.0.0 before 10.0.10 Denial of Service via SMTP Reply Parsing

Nodemailer from 3.0.0 before 10.0.10 contains a quadratic complexity denial of service vulnerability in the SMTP client reply parser in SMTPConnection.onData and isPartialResponse. A malicious SMTP server or on-path attacker can stream continuation lines without a completion line before...

Important: expat

Issue Overview: Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity in the storeAtts function in xmlparse.c, where processing N specified attributes with non-normalized values triggers an ON^2 linear scan of elementType-defaultAtts to determin...

Amazon Linux 2 : expat (ALAS-2026-3965)

The version of expat installed on the remote host is prior to 2.1.0-15. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3965 advisory. Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity in the storeAtts function ...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...
