CVE-ID: CVE-2021-4037

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions in the fs/inode.c:inode_init_owner() function logic of the Linux kernel. A local user can create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set to bypass implemented security restrictions and gain unauthorized access to the application.

The vulnerability exists due to a double free error within the network packet scheduler implementation in the route4_change() function in Linux kernel when removing all references to a route filter before freeing it. A local user can run a specially crafted program to crash the kernel or execute arbitrary code.

Mitigation

Install updates from vendor's repository.

CVE-ID: CVE-2022-2602

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

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

The vulnerability exists due to a use-after-free error caused by an io_uring request, which is being processed on a registered file. The Unix GC runs and frees the io_uring file descriptor and all the registered file descriptors in a specific order that may allow a local user to win a race and execute arbitrary code with elevated privileges.
