3) NULL pointer dereference

EUVDB-ID: #VU61270

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-25258

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package linux to the latest version.

4) Exposure of Resource to Wrong Sphere

EUVDB-ID: #VU61269

Risk: Low

CVSSv4.0: 1.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2022-25375

CWE-ID: CWE-668 - Exposure of resource to wrong sphere

Exploit availability: Yes

Description

The 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.

Mitigation

5) Buffer overflow

EUVDB-ID: #VU62601

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-26490

CWE-ID: CWE-119 - Memory corruption
