Red Hat Security Advisory 2023-7077-01 - An update for kernel is now available for Red Hat Enterprise Linux 8. Issues addressed include buffer overflow, denial of service, double free, information leakage, memory leak, null pointer, out of bounds access, out of bounds write, and use-after-free vulnerabilities.
Dell VxRail, version(s) 8.0.100 and earlier contain a denial-of-service vulnerability in the upgrade functionality. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to degraded performance and system malfunction.
A double-free flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw allows a local user to crash or potentially escalate their privileges on the system.
Red Hat Security Advisory 2023-1470-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include a double free vulnerability.
Red Hat Security Advisory 2023-1468-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include a double free vulnerability.
Red Hat Security Advisory 2023-1467-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include a double free vulnerability.
Red Hat Security Advisory 2023-1469-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include a double free vulnerability.
Red Hat Security Advisory 2023-1471-01 - This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel. Issues addressed include a double free vulnerability.
