Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) Google Chrome (affected versions not specified)

Description A bug in the Linux kernel's regsafe() function occurs when rold->reg->range is BEYOND PKT END and rcur->reg->range is N, potentially causing the function to return true and preventing the exploration of valid packet ranges.

In Google Chrome, the DevTools component contains insufficient input validation, which could allow a remote attacker to bypass security restrictions via a specially crafted HTML page.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
