CVE-2025-61663Grub2: missing unregister call for normal commands may lead to use-after-free

GNU grub2; Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8 Veröffentlicht: (vor 11 Monaten)

Beschreibung

A vulnerability has been identified in the GRUB2 bootloader's normal command that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the normal command is not properly unregistered when the module is unloaded. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability. Impact on the data integrity and confidentiality is also not discarded.

Schwachstellentyp (CWE): CWE-825

Podman: containers-common: containers-common: default seccomp af_vsock/netlink_audit deny rules bypassable via 32-bit truncation

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9; Red Hat Red Hat Hardened Images

A flaw was found in the default seccomp profile used by Podman via containers-common. Deny rules for AF_VSOCK and NETLINK_AUDIT compared socket arguments with unmasked 64-bit equality. Because the kernel truncates those int arguments to 32 bits, setting upper…

Dbus: dbus-daemon: dbus-daemon aborts (reply_serial != 0) when a broadcast from the driver cannot be delivered to a monitored bus

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8

A flaw was found in D-Bus. With a privileged Monitoring client attached (for example dbus-monitor or busctl monitor), an unprivileged local user can cause dbus-daemon to abort if a driver-originated broadcast such as NameOwnerChanged or ActivatableServicesCha…

Red Hat Migration Toolkit for Applications 8; Red Hat Migration Toolkit for Virtualization; Red Hat OpenShift Service Mesh 3; Red Hat Red Hat Advanced Cluster Management for Kubernetes 2

A flaw was found in the ansible-core user module. When generate_ssh_key is enabled, User.ssh_key_gen() guards the key files against symlinks but checks the ~/.ssh directory only with os.path.exists(). An unprivileged user on a managed node who replaces their …
