In the Linux kernel, the following vulnerability has been resolved: ext4: fix another off-by-one fsmap error on 1k block filesystems Apparently syzbot figured out that issuing this FSMAP call: struct fsmaphead cmd = .fmhcount = ...; .fmhkeys = .fmrdevice = / ext4 dev /, .fmrphysical = 0, ,...
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-2023-53101 ext4: zero i_disksize when initializing the bootloader inode
In the Linux kernel, the following vulnerability has been resolved: ext4: zero idisksize when initializing the bootloader inode If the boot loader inode has never been used before, the EXT4IOCSWAPBOOT inode will initialize it, including setting the isize to 0. However, if the "never before used"...
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...
