CVE-2026-119378: SQLite before 3.54.0 Use-After-Free in R-Tree nodeWrite()

Noroxi assessment

Priority: Monitor (action score 27/100)

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: 0.25% (FIRST EPSS).
Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
Fixed version: azl3 libdb 5.3.28-9 on Azure Linux 3.0 Release Notes; azl3 sqlite 3.44.0-4 on Azure Linux 3.0 Release Notes.

Low priority for now. Upgrade to azl3 libdb 5.3.28-9 on Azure Linux 3.0 Release Notes; azl3 sqlite 3.44.0-4 on Azure Linux 3.0 Release Notes or later.

Primary sources: NVD · CVE.org · FIRST EPSS

SQLite before 3.54.0 contains a use-after-free vulnerability in the R-Tree extension that allows attackers to make applications use freed heap memory by manipulating the %_node shadow table. Attackers can supply a database declaring %_node WITHOUT ROWID or with a RAISE(IGNORE) trigger so nodeWrite() hashes nodes as 0, crashing the process after node splits.

After a memory region is freed, another reference pointing to it is still used. By then, the same region may have been allocated for different data.
