CVE-2024-34027: f2fs: compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.23% (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 0a4ed2d97cb6d044196cc3e726b6699222b41019, 329edb7c9e3b6ca27e6ca67ab1cdda1740fb3a2b, 5d47d63883735718825ca2efc4fca6915469774f.

Low priority for now. Upgrade to Linux Linux 0a4ed2d97cb6d044196cc3e726b6699222b41019, 329edb7c9e3b6ca27e6ca67ab1cdda1740fb3a2b, 5d47d63883735718825ca2efc4fca6915469774f or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock It needs to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock to avoid racing with checkpoint, otherwise, filesystem metadata including blkaddr in dnode, inode fields and .total_valid_block_count may be corrupted after SPO case.
