Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Memory leak (CVE-ID: CVE-2023-1074)

The vulnerability allows a local user to perform DoS attack on the target system.

The vulnerability exists due memory leak in Linux kernel Stream Control Transmission Protocol. A local user can start a malicious network service and then connect to remotely, forcing the kernel to leak memory.


2) Use-after-free (CVE-ID: CVE-2023-1079)

The vulnerability allows an attacker to compromise the vulnerable system.

The vulnerability exists due to a use-after-free error within the asus_kbd_backlight_set() function when plugging in a malicious USB device. An attacker with physical access to the system can inject a malicious USB device, trigger a use-after-free error and execute arbitrary code.



3) Buffer overflow (CVE-ID: CVE-2023-1073)

The vulnerability allows an attacker to compromise the affected system.

The vulnerability exists due to a boundary error in the Linux kernel human interface device (HID) subsystem. An attacker with physical access to the system can insert in a specific way malicious USB device, trigger memory corruption and execute arbitrary code.


4) NULL pointer dereference (CVE-ID: CVE-2023-1382)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in net/tipc/topsrv.c within the TIPC protocol implementation in the Linux kernel. A local user can perform a denial of service (DoS) attack.


5) Use-after-free (CVE-ID: CVE-2023-25012)

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the bigben_remove() function in drivers/hid/hid-bigbenff.c. An attacker with physical access to the system can attach a specially crafted USB device to the system and cause a denial of service condition.
