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...
