CVE-2023-39198: cve-details
A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.

Red Hat Security Advisory 2024-2394-03 - An update for kernel is now available for Red Hat Enterprise Linux 9. Issues addressed include code execution, double free, integer overflow, memory exhaustion, memory leak, null pointer, out of bounds access, out of bounds read, out of bounds write, privilege escalation, and use-after-free vulnerabilities.
Ubuntu Security Notice 6549-5 - 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. Lin Ma discovered that the Netlink Transformation subsystem in the Linux kernel did not properly initialize a policy data structure, leading to an out-of-bounds vulnerability. A local privileged attacker could use this to cause a denial of service or possibly expose sensitive information.
