发布于3月6日3月6日 Members SUSE: CVE-2024-35986: SUSE Linux Security Advisory Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/20/2024 Created 06/24/2024 Added 06/24/2024 Modified 08/28/2024 Description In the Linux kernel, the following vulnerability has been resolved: phy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered The power_supply frame-work is not really designed for there to be long living in kernel references to power_supply devices. Specifically unregistering a power_supply while some other code has a reference to it triggers a WARN in power_supply_unregister(): WARN_ON(atomic_dec_return(&psy->use_cnt)); Folllowed by the power_supply still getting removed and the backing data freed anyway, leaving the tusb1210 charger-detect code with a dangling reference, resulting in a crash the next time tusb1210_get_online() is called. Fix this by only holding the reference in tusb1210_get_online() freeing it at the end of the function. Note this still leaves a theoretical race window, but it avoids the issue when manually rmmod-ing the charger chip driver during development.
