CVE-ID: CVE-2022-0644

CWE-ID: CWE-617 - Reachable Assertion

Exploit availability: No

Description

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

The vulnerability exists due to a reachable assertion error in the Linux kernel’s kernel_read_file_from_fd in the filesystem. A local user can attempt to read a file without read access/permission to perform a denial of service (DoS) attack.

CVE-ID: CVE-2022-22942

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: Yes

Description

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

The vulnerability exists due to an error in the vmwgfx driver in Linux kernel. A local unprivileged user can gain access to files opened by other processes on the system through a dangling 'file' pointer.

Exploiting this vulnerability requires an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor.

49) Missing initialization of resource

CVE-ID: CVE-2022-24448

CWE-ID: CWE-909 - Missing initialization of resource

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to missing initialization of resource within the fs/nfs/dir.c in the Linux kernel. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.

CVE-ID: CVE-2022-24959

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

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

The vulnerability exists due to memory leak within the yam_siocdevprivate() function in drivers/net/hamradio/yam.c. A local user can perform a denial of service attack.

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.

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.
