Dell vApp Manger, versions prior to 9.2.4.x contain an arbitrary file read vulnerability. A remote attacker could potentially exploit this vulnerability to read arbitrary files from the target system.

Ubuntu Security Notice 6460-1 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform data buffer size validation in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service or possibly expose sensitive information.

Vulnerability in the Sun ZFS Storage Appliance product of Oracle Systems (component: Core). The supported version that is affected is 8.8.60. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Sun ZFS Storage Appliance. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Sun ZFS Storage Appliance. CVSS 3.1 Base Score 5.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).

Red Hat Security Advisory 2023-5622-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include memory leak, privilege escalation, and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-5603-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include denial of service, out of bounds write, and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-5221-01 - 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 out of bounds write and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-5069-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include bypass, information leakage, and use-after-free vulnerabilities.

It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Querijn Voet discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other vulnerabilities were also discovered and addressed.
