Overview
CVE-2026-74358 is a known-severity vulnerability. It was published on August 15, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix fast commit wait/wake bit mapping on 64-bit
On 64-bit, ext4 dynamic inode states live in the upper half of i_flags,
and ext4_test_inode_state() applies the corresponding +32 offset.
The fast-commit wait and wake paths open-coded the wait key with the raw
EXT4_STATE_* value. Add small helpers for the state wait word and bit,
and use them for the FC_COMMITTING and FC_FLUSHING_DATA waits so the wait
key follows the same mapping as the state helpers.
Remediation

How can CyberStrike help with CVE-2026-74358?
CyberStrike is an open-source, AI-augmented pentesting engine.
