CVE-2024-40903 Open this link in a new tabHow to fix?
Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.22.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: fix use-after-free case in tcpm_register_source_caps
There could be a potential use-after-free case in tcpm_register_source_caps(). This could happen when:
- new (say invalid) source caps are advertised
- the existing source caps are unregistered
- tcpm_register_source_caps() returns with an error as usb_power_delivery_register_capabilities() fails
This causes port->partner_source_caps to hold on to the now freed source caps.
Reset port->partner_source_caps value to NULL after unregistering existing source caps.
