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...
