CVE-2021-4037 (GCVE-0-2021-4037)

Vulnerability from cvelistv5

Published

2022-08-24 00:00

Modified

2024-08-03 17:16

Severity ?

CWE

CWE-284 - - Improper Access Control

Summary

A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS.

CVE-2021-20322 (GCVE-0-2021-20322)

Vulnerability from cvelistv5

Published

2022-02-18 17:50

Modified

2024-08-03 17:37

Severity ?

CWE

CWE-330

Summary

A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well.
