CVE-2026-74308 ext4: fix kernel BUG in ext4_write_inline_data_end

In the Linux kernel, the following vulnerability has been resolved: ext4: fix kernel BUG in ext4writeinlinedataend When the data=journal mount option is used, the ext4journalledwriteend function incorrectly calls ext4writeinlinedataend without checking if the EXT4STATEMAYINLINEDATA flag is still...

CVE-2026-74308

Summary: CVE-2026-74308 affects the Linux kernel ext4 in the data=journal scenario. The bug was that ext4_journalled_write_end() could call ext4_write_inline_data_end() without verifying EXT4_STATE_MAY_INLINE_DATA, if a prior inline data conversion failed. This could leave i_inline_size unexpande...

CVE-2026-72225

The CVE-2026-72225 issue is in the Linux kernel’s journal code (jbd2). A numeric underflow occurs in jbd2_journal_initialize_fast_commit() when calculating journal capacity with (journal->j_last - num_fc_blks) where both operands are unsigned; if num_fc_blks > j_last, the subtraction wraps ...

CVE-2026-72193

CVE-2026-72193 concerns the in-tree ntfs3 kernel driver. A crafted NTFS3 disk image could trigger an in-kernel infinite loop during mount via a corrupted RESTART_TABLE free-chain, hanging the mounting thread and potentially invoking the soft-lockup watchdog on multi-CPU systems. The vulnerability...

CVE-2026-72163

The vulnerability CVE-2026-72163 affects the Linux kernel OCFS2 journaling path. The issue arises in ocfs2_assure_trans_credits: when a journal aborts during DIO completion, a NULL h_transaction dereference can occur because the handle’s aborted state isn’t checked before reading remaining credit...
