CVE-2026-89475: power: supply: bq24257: fix use-after-free on remove

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 47ccbad210f48721c30d69d65b83dc9fff919ca9, 6d2eb93975c07b0169a3287efc1ae3b60cf52d8e, 861ec73ce86e2ca18082cc7be4f140a5bbdf1428.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 47ccbad210f48721c30d69d65b83dc9fff919ca9, 6d2eb93975c07b0169a3287efc1ae3b60cf52d8e, 861ec73ce86e2ca18082cc7be4f140a5bbdf1428 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: power: supply: bq24257: fix use-after-free on remove The STAT-pin interrupt is devm-managed, so it stays armed until the devm cleanup that runs after remove() returns. remove() cancels bq->iilimit_setup_work while the threaded handler can still fire; that handler reschedules the work and dereferences bq, so the work runs against freed memory once devm frees bq. Make the delayed work device-managed with devm_delayed_work_autocancel(), registered before the interrupt request. The devm cleanup then releases the interrupt first, so the handler can no longer reschedule the work, and cancels the work before bq is freed. The explicit cancel_delayed_work_sync() in remove() is no longer needed and is dropped. Found by static analysis.
