Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the Linux kernel's fscrypt, where the keyring is not properly destroyed after security sb delete, leading to a potential NULL dereference. This problem occurs whe...

The vulnerability of the fscrypt component in the Linux operating system’s kernel allows a hacker to trigger a service failure or increase their privileges.

The vulnerability of the fscrypt component in the Linux operating system’s kernel is related to the assignment of the zero pointer. Exploiting this vulnerability can allow an attacker to cause service failures or increase their privileges by revoking the keyrings used for encrypting ext4, f2fs, o...

SUSE CVE-2018-14616

An issue was discovered in the Linux kernel through 4.17.10. There is a NULL pointer dereference in fscryptdopagecrypto in fs/crypto/crypto.c when operating on a file in a corrupted f2fs image...

SUSE CVE-2022-25328

The bashcompletion script for fscrypt allows injection of commands via crafted mountpoint paths, allowing privilege escalation under a specific set of circumstances. A local user who has control over mountpoint paths could potentially escalate their privileges if they create a malicious mountpoin...

SUSE CVE-2022-25326

fscrypt through v0.3.2 creates a world-writable directory by default when setting up a filesystem, allowing unprivileged users to exhaust filesystem space. We recommend upgrading to fscrypt 0.3.3 or above and adjusting the permissions on existing fscrypt metadata directories where applicable...

SUSE CVE-2022-25327

The PAM module for fscrypt doesn't adequately validate fscrypt metadata files, allowing users to create malicious metadata files that prevent other users from logging in. A local user can cause a denial of service by creating a fscrypt metadata file that prevents other users from logging into the...
