- Summary
- CVE-2026-98758 affecting package kernel 6.6.157.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: glink: fix use-after-free of ucsi on remove
The pmic_glink client is released by the devres cleanup, which runs after pmic_glink_ucsi_remove() has returned, so its notification callbacks can queue work until then. Work that runs after ucsi_unregister() has been called touches freed state: it dereferences the connector array that ucsi_unregister() freed, or registers and unregisters the instance a second time.
Disable both work items with disable_work_sync() before unregistering, and unregister only if the instance is still registered.
This issue was found by an in-house static analysis tool.
