CVE-2023-53143

CVE-2023-53143 is a Linux kernel ext4 off-by-one fsmap bug for 1k-block filesystems. The crash stems from insufficient range validation in ext4_getfsmap_datadev when querying GETFSMAP, due to s_first_data_block being nonzero on 1k blocks, causing an underflow and invalid group calculation. A fix ...

CVE-2023-53100

The CVE-2023-53100 entry relates to the Linux kernel ext4 code path. The issue was triggered during inline data handling when adding xattrs to an inode: after ext4_xattr_shift_entries(), i_inline_off can be incorrectly updated (reported as changing to 176), which can cause ext4_update_inline_dir/...

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...
