kernel: ext4: don't set SB_RDONLY after filesystem errors

A flaw was found in the Linux kernel's handling of filesystem errors. When a filesystem encounters an error and is configured to remount as read-only, the kernel's attempt to apply this setting can conflict with other filesystem operations, specifically during filesystem freezing. This conflict c...

kernel: nfsd: map the EBADMSG to nfserr_io to avoid warning

In the Linux kernel, the following vulnerability has been resolved: nfsd: map the EBADMSG to nfserrio to avoid warning Ext4 will throw -EBADMSG through ext4readdir when a checksum error occurs, resulting in the following WARNING. Fix it by mapping EBADMSG to nfserrio. nfsdbufferedreaddir iterated...

kernel: ext4: update orig_path in ext4_find_extent()

A flaw was found in the Linux kernel's ext4 filesystem. When the ext4findextent function reallocates a path, it fails to update the original path pointer. A local attacker could exploit this by triggering a specific sequence of filesystem operations, leading to a null pointer dereference and...

kernel: ext4: check stripe size compatibility on remount as well

In the Linux kernel, the following vulnerability has been resolved: ext4: check stripe size compatibility on remount as well We disable stripe size in ext4fillsuper if it is not a multiple of the cluster ratio however this check is missed when trying to remount. This can leave us with cases where...

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

A flaw was found in the Linux kernel's ext4 filesystem. This flaw occurs due to a double brelse operation on a buffer in the extents path, meaning the same memory buffer is released twice. An attacker with administrative root privileges could exploit this vulnerability, leading to a system crash...

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

A flaw was found in the Linux kernel's ext4 filesystem. This use-after-free vulnerability occurs in the ext4extshowleaf function when a previously freed or reallocated memory path is incorrectly used. This issue is only triggered when the EXTDEBUG option is enabled, which means it does not affect...

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

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs when an attempt is made to mount an ext4 filesystem using the DXHASHSIPHASH default hash version on a filesystem that does not have the casefold feature enabled. Under these specific conditions, the mounting process...

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 access to uninitialised lock in fc replay path

A flaw was found in the Linux kernel. When the ext4 filesystem's fast-commit feature is enabled, a local attacker could trigger a condition where an uninitialized lock is accessed during the filesystem's replay path. This can lead to a system crash, resulting in a denial of service...

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: fix i_data_sem unlock order in ext4_ind_migrate()

A flaw was found in the kernel's ext4 filesystem. When an EXT4IOCMIGRATE ioctl input/output control operation, requiring synchronous updates, races with a write2 system call, it can lead to a deadlock. This deadlock occurs specifically when the CONFIGPROVELOCKING option is enabled, potentially...

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...
