CVE-2023-54096: soundwire: fix enumeration completion

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: 0.16% (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 48d1d0ce0782f995fda678508fdae35c5e9593f0, a36b522767f3a72688893a472e80c9aa03e67eda, c40d6b3249b11d60e09d81530588f56233d9aa44.

Low priority for now. Upgrade to Linux Linux 48d1d0ce0782f995fda678508fdae35c5e9593f0, a36b522767f3a72688893a472e80c9aa03e67eda, c40d6b3249b11d60e09d81530588f56233d9aa44 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: soundwire: fix enumeration completion The soundwire subsystem uses two completion structures that allow drivers to wait for soundwire device to become enumerated on the bus and initialised by their drivers, respectively. The code implementing the signalling is currently broken as it does not signal all current and future waiters and also uses the wrong reinitialisation function, which can potentially lead to memory corruption if there are still waiters on the queue. Not signalling future waiters specifically breaks sound card probe deferrals as codec drivers can not tell that the soundwire device is already attached when being reprobed. Some codec runtime PM implementations suffer from similar problems as waiting for enumeration during resume can also timeout despite the device already having been enumerated.
