CVE-2023-53101

CVE-2023-53101 affects the Linux kernel ext4 bootloader inode handling. The issue arises when EXT4_IOC_SWAP_BOOT initializes an inode with a non-zero i_size, causing i_disksize to remain non-zero and creating an i_size vs i_disksize inconsistency that can trigger a kernel warning (as shown in the...

CVE-2023-53089

CVE-2023-53089 affects the Linux kernel ext4/xattr path. The issue occurs during eviction of inodes with extended attributes (EA) where ext4_xattr_delete_inode triggers a hang due to finding an EA inode (ea_inum = 15) that is in I_FREEING state and waiting for the EA inode’s deletion, causing an ...
