Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2022-0435
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Linux kernel networking module for the Transparent Inter-Process Communication (TIPC) protocol. A remote unauthenticated attacker can send specially crafted traffic to the system, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the TIPC bearer is set up.

No. We are not aware of malware exploiting this vulnerability.
5) Use-after-free
EUVDB-ID: #VU61181
Risk: Low
CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-0487
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a use-after-free error in rtsx_usb_ms_drv_remove in drivers/memstick/host/rtsx_usb_ms.c in memstick in the Linux kernel. A local user can trigger a use-after-free error and gain access to sensitive information.

CVE-ID: CVE-2022-25375
CWE-ID:
CWE-668 - Exposure of resource to wrong sphere
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to improper access restrictions in drivers/usb/gadget/function/rndis.c in the Linux kernel. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. A local user can run a specially crafted program to gain access to kernel memory.

CVE-ID: CVE-2022-25258
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error drivers/usb/gadget/composite.c in the Linux kernel. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). A local user can run a specially crafted program to trigger memory corruption and perform a denial of service (DoS) attack.
