kernel: ext4: make sure the first directory block is not a hole

The syzbot constructs a directory that has no dirblock but is non-inline, i.e. the first directory block is a hole. And no errors are reported when creating files in this directory. Then, we get a directory block without '.' and '..' but with a valid dentry. This may cause some code that relies o...

kernel: ext4: fix infinite loop when replaying fast_commit

In the Linux kernel, the following vulnerability has been resolved: ext4: fix infinite loop when replaying fastcommit When doing fastcommit replay an infinite loop may occur due to an uninitialized extentstatus struct. ext4extdetermineinserthole does not detect the replay and calls...

kernel: ext4: update orig_path in ext4_find_extent()

In the Linux kernel, the following vulnerability has been resolved: ext4: update origpath in ext4findextent In ext4findextent, if the path is not big enough, we free it and set origpath to NULL. But after reallocating and successfully initializing the path, we don't update origpath, in which case...

kernel: ext4: dax: fix overflowing extents beyond inode size when partially writing

An inode corruption flaw was found in the Linux kernel's Ext4 file system functionality related to how a user can interrupt a write using the daxiomaprwfunction. This flaw allows a local user to make non-fatal mistakes with Ext4, leading to a file system denial of service...

kernel: ext4: fix access to uninitialised lock in fc replay path

In the Linux kernel, the following vulnerability has been resolved: ext4: fix access to uninitialised lock in fc replay path The following kernel trace can be triggered with fstest generic/629 when executed against a filesystem with fast-commit feature enabled: INFO: trying to register non-static...

kernel: ext4: filesystems without casefold feature cannot be mounted with siphash

In the Linux kernel, the following vulnerability has been resolved: ext4: filesystems without casefold feature cannot be mounted with siphash When mounting the ext4 filesystem, if the default hash version is set to DXHASHSIPHASH but the casefold feature is not set, exit the mounting...

kernel: ext4: avoid use-after-free in ext4_ext_show_leaf()

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid use-after-free in ext4extshowleaf In ext4findextent, path may be freed by error or be reallocated, so using a previously saved ppath may have been freed and thus may trigger use-after-free, as follows: ext4splitextent...

kernel: ext4: drop ppath from ext4_ext_replay_update_ex() to avoid double-free

In the Linux kernel, the following vulnerability has been resolved: ext4: drop ppath from ext4extreplayupdateex to avoid double-free When calling ext4forcesplitextentat in ext4extreplayupdateex, the 'ppath' is updated but it is the 'path' that is freed, thus potentially triggering a double-free i...

kernel: ext4: fix timer use-after-free on failed mount

In the Linux kernel, the following vulnerability has been resolved: ext4: fix timer use-after-free on failed mount Syzbot has found an ODEBUG bug in ext4fillsuper The deltimersync function cancels the serrreport timer, which reminds about filesystem errors daily. We should guarantee the timer is ...

kernel: ext4: aovid use-after-free in ext4_ext_insert_extent()

In the Linux kernel, the following vulnerability has been resolved: ext4: aovid use-after-free in ext4extinsertextent As Ojaswin mentioned in Link, in ext4extinsertextent, if the path is reallocated in ext4extcreatenewleaf, we'll use the stale path and cause UAF. Below is a sample trace with dumm...

kernel: ext4: fix double brelse() the buffer of the extents path

In the Linux kernel, the following vulnerability has been resolved: ext4: fix double brelse the buffer of the extents path In ext4exttrytomergeup, set path1.pbh to NULL after it has been released, otherwise it may be released twice. An example of what triggers this is as follows: split2 map split...

kernel: ext4: sanity check for NULL pointer after ext4_force_shutdown

REJECTED CVE A NULL pointer dereference vulnerability has been identified in the Linux Kernel's ext4 filesystem. The issue occurs during concurrent write operations with inline data, where an ext4forceshutdown is triggered due to inconsistencies like "block bitmap and bg descriptor inconsistent."...
