Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Keys: Fixed the issue of linking a duplicate key to a keyring’s assocarray. When making a DNS query within the kernel using dnsquery, the request code can, in rare cases, create a duplicate index key in the assocarray of the...

CVE-2026-50029

js-toml is a TOML parser for JavaScript, Prior to version 1.1.2, the interpreter checks whether a key already exists in a parser-built container with if objectkey instead of if key in object. When the prior value is a falsy primitive — false, 0, 0n, 0.0, -0, or "" — the duplicate-key branch is...

CVE-2026-50029

Affects js-toml prior to 1.1.2. The parser uses if (object[key]) to decide duplicates, causing falsy primitives (false, 0, 0n, 0.0, -0, "") to be overwritten by later keys; this yields structural type confusion in load() output (e.g., isAdmin becomes truthy object). MITRE/ATT&CK not specified in ...

CVE-2026-59870

js-yaml is a JavaScript YAML parser and dumper. From 5.0.0 before 5.2.1, YAML11SCHEMA support for the !!omap tag in src/tag/sequence/omap.ts uses omapTag.addItem to perform a linear duplicate-key scan on every insertion, causing On^2 CPU consumption when yaml.load parses a crafted ordered-map...
