CVE-ID: CVE-2022-3424
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the gru_set_context_option(), gru_fault() and gru_handle_user_call_os() functions in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Install updates from vendor's repository.

2) Improper access control
EUVDB-ID: #VU71541
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4662
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper access restrictions in the Linux kernel USB core subsystem in the way user attaches usb device. A local user can perform a denial of service (DoS) attack.

3) Use-after-free
EUVDB-ID: #VU70508
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-47946
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the io_sqpoll_wait_sq() function in fs/io_uring.c. A remote attacker can crash the kernel by forking a process and then quickly terminating it.
