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: Linux kernel OverlayFS: Kernel crash via null pointer dereference in ovl_get_acl_rcu()

A flaw was found in the OverlayFS ovl component of the Linux kernel. A local user can trigger a null pointer dereference by performing a specific sequence of file system operations. This vulnerability occurs when the ovlgetaclrcu function attempts to access a real inode that has been set to NULL...

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

In the Linux kernel, the following vulnerability has been resolved: ext4: don't set SBRDONLY after filesystem errors When the filesystem is mounted with errors=remount-ro, we were setting SBRDONLY flag to stop all filesystem modifications. We knew this misses proper locking sb-sumount and does no...

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...
