1) Use-after-free (CVE-ID: CVE-2023-0128)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the Overview Mode component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger use-after-free error and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


2) Heap-based buffer overflow (CVE-ID: CVE-2023-0129)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted HTML content in Network Service. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.


3) Buffer overflow (CVE-ID: CVE-2022-4139)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the i915 kernel driver on Linux kernel. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.



4) Stack-based buffer overflow (CVE-ID: CVE-2022-4378)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.


5) Integer overflow (CVE-ID: CVE-2022-45934)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow within the l2cap_config_req() function in net/bluetooth/l2cap_core.c in Linux kernel. A local user can pass specially crafted L2CAP_CONF_REQ packets to the device, trigger an integer overflow and execute arbitrary code with elevated privileges.
