USN-6549-4: Linux kernel (Intel IoTG) vulnerabilities

It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service system crash. CVE-2023-37453 Lin Ma...

SUSE CVE-2023-6931

A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation. A perfevent's readsize can overflow, leading to an heap out-of-bounds increment or write in perfreadgroup. We recommend upgrading past commit...
