CVE-2024-33847 f2fs: compress: don't allow unaligned truncation on released compress inode

In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: don't allow unaligned truncation on released compress inode f2fs image may be corrupted after below testcase: - mkfs.f2fs -O extraattr,compression -f /dev/vdb - mount /dev/vdb /mnt/f2fs - touch /mnt/f2fs/file -...

CVE-2024-33847

CVE-2024-33847 relates to the Linux kernel’s f2fs compression feature. The root cause is a truncation bug on released compressed inodes that can corrupt a f2fs image if a partial truncation changes the valid block count without updating i_blocks/total_valid_block_count. The patch fixes by allowin...
