CVE-2023-53835 ext4: don't clear SB_RDONLY when remounting r/w until quota is re-enabled

In the Linux kernel, the following vulnerability has been resolved: ext4: don't clear SBRDONLY when remounting r/w until quota is re-enabled When a file system currently mounted read/only is remounted read/write, if we clear the SBRDONLY flag too early, before the quota is initialized, and there ...

CVE-2023-53835

The CVE-2023-53835 entry concerns the Linux kernel ext4 filesystem: when remounting from read-only to read/write, SB_RDONLY can be cleared before quota is initialized, potentially triggering a WARN_ON_ONCE(dquot_initialize_needed(inode)) in ext4_xattr_block_set(). The issue is documented with a d...
