The vulnerability of the ext4_xattr_set_entry() function in the fs/ext4/xattr.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of data.

The vulnerability of the ext4xattrsetentry function in the fs/ext4/xattr.c module of the Linux kernel is related to incorrect calculation of the available storage space for storing attributes. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
