kernel: Linux kernel (CIFS): Use-after-free vulnerability allows data integrity compromise and denial of service

A flaw was found in the Linux kernel's Common Internet File System CIFS component. This use-after-free vulnerability occurs due to improper handling of server hostname information during connection re-establishment. An attacker on an adjacent network could exploit this, potentially leading to a...

kernel: Bluetooth: hci_event: call disconnect callback before deleting conn

A flaw was found in the Linux kernel in which a callback is not called when a Bluetooth peripheral is disconnected. This flaw leads to a use-after-free, which an attacker could use to escalate their privileges, corrupt system memory, or otherwise cause a denial of service...

kernel: ipv6: use RCU in ip6_output()

A use-after-free flaw was found in ip6finishoutput2 in net/ipv6/ip6output.c in ipv6 access. This flaw could allow an attacker to crash the system at device disconnect. This vulnerability could even lead to a kernel information leak problem...

Siemens SIMATIC and SIPLUS products Uncontrolled Resource Consumption (CVE-2025-40944)

Affected devices do not properly handle S7 protocol session disconnect requests. When receiving a valid S7 protocol Disconnect Request COTP DR TPDU on TCP port 102, the devices enter an improper session state. This could allow an attacker to cause the device to become unresponsive, leading to a...

The vulnerabilities of the `usbnet_stop()` and `usbnet_disconnect()` functions in the Linux operating system allow attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the usbnetstop and usbnetdisconnect functions in the Linux operating system is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of protected...
