CVE-2025-22120: ext4: goto right label 'out_mmap_sem' in ext4_setattr()

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 32d872e3905746ff1048078256cb00f946b97d8a, 45314999f950321a341033ae8f9ac12dce40669b, 551667f99bcf04fa58594d7d19aef73c861a1200.

Low priority for now. Upgrade to Linux Linux 32d872e3905746ff1048078256cb00f946b97d8a, 45314999f950321a341033ae8f9ac12dce40669b, 551667f99bcf04fa58594d7d19aef73c861a1200 or later.

In the Linux kernel, the following vulnerability has been resolved: ext4: goto right label 'out_mmap_sem' in ext4_setattr() Otherwise, if ext4_inode_attach_jinode() fails, a hung task will happen because filemap_invalidate_unlock() isn't called to unlock mapping->invalidate_lock. Like this: EXT4-fs error (device sda) in ext4_setattr:5557: Out of memory INFO: task fsstress:374 blocked for more than 122 seconds.
