CVE-2023-53420

CVE-2023-53420 affects the Linux kernel NTFS code path. The issue arises in ntfs_listxattr() (fs/ntfs3/xattr.c) where slab-out-of-bounds access could occur due to incorrect handling in the ea_all iteration when aea->name_len is 0, potentially reading invalid memory during listxattr(). The vend...

grub2: UFS: Integer overflow may lead to heap based out-of-bounds write when handling symlinks

A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grubmalloc may be called with a smaller...

grub2: fs/ufs: OOB write in the heap

A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure...
