Weekly CVE digest
One email a week with newly published vulnerabilities worth knowing about. No account needed.
This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.
A vulnerability has been identified in the Linux kernel related to improper reference counting management in the 'xfrm_state' structure. The issue occurs during the NETDEV_UNREGISTER event, leading to reference count leaks.
When addressparser finds no address by its strict reading, it falls back to pulling one out of the free text with /\s*\b[^@\s]+@[^\s]+\b\s*/. That pattern backtracks quadratically, causing high resource consumption when processing a single header.
