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...
The vulnerability of the hciSyncConnCompleteEvt() function in the net/bluetooth/hciEvent.c module of the Bluetooth subsystem in the Linux operating system allows a malicious actor to cause a service failure.
The vulnerability of the hciSyncConnCompleteEvt function in the net/bluetooth/hciEvent.c module of the Bluetooth subsystem in the Linux operating system is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...
The vulnerability of the hci_conn_del() function in the net/bluetooth/hci_conn.c module of the Linux kernel’s Bluetooth subsystem allows a attacker to cause a service failure.
The vulnerability of the hciconndel function in the net/bluetooth/hciconn.c module of the Bluetooth subsystem in the Linux operating system is related to improper control of resource identifiers “resource injection”. Exploiting this vulnerability could allow a attacker to cause service failures...
The vulnerability of the `sco_sock_kill()` function in the `net/bluetooth/sco.c` module of the Linux kernel’s Bluetooth subsystem allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.
The vulnerability of the scosockkill function in the net/bluetooth/sco.c module of the Linux kernel’s Bluetooth subsystem is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibili...
