Answer in brief
CVE-2026-74370 records a Unknown severity vulnerability in liveupdate: fix TOCTOU race in luo_session_retrieve(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: liveupdate: fix TOCTOU race in luo_session_retrieve() Extend the scope of the rwsem_read lock in luo_session_retrieve() to overlap with the acquisition of the session mutex. This prevents a concurrent thread from releasing and freeing the session between the lookup and the mutex lock.
