CVE-ID: CVE-2021-0920

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the unix_scm_to_skb() function of af_unix.c in Linux kernel. A local user can run a specially crafted program to trigger a race condition and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

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.

Mitigation

Update the affected package the Linux Kernel to the latest version.

17) Missing initialization of resource

Risk: Low

CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

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.

Mitigation

Update the affected package the Linux Kernel to the latest version.

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-2022-25258

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
