CVE-2026-89464: power: supply: twl4030_charger: cancel workers via devm

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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 6eba34732524067da2aad5ddfdfbc641ded10e9e, 72a2d6cd049f892853e4e2d8d8fc5e7d0244a458, 9644c96ef8646c65d46caa5139a6631e29b79d6c.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 6eba34732524067da2aad5ddfdfbc641ded10e9e, 72a2d6cd049f892853e4e2d8d8fc5e7d0244a458, 9644c96ef8646c65d46caa5139a6631e29b79d6c or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: power: supply: twl4030_charger: cancel workers via devm bci is devm-allocated. Two workers (bci->work and bci->current_worker) dereference it. twl4030_bci_remove() disables charging and masks interrupts. It cancels neither worker. A worker pending at remove() can run after devm frees bci. The USB transceiver comes from devm_usb_get_phy_by_node(). devm unregisters its notifier only after remove() returns. A cancel_work_sync() in remove() can then race a notifier reschedule. devm_work_autocancel() and devm_delayed_work_autocancel() avoid that. They cancel the workers during devm release, before bci is freed. The current_worker is registered first, since devm will cancel in reverse order and bci->work can reschedule current_worker.
