Detailsinfo

A vulnerability was found in Linux Kernel up to 6.11.6 and classified as problematic. Affected by this issue is an unknown functionality of the component qmp-usbc. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usbc: fix NULL-deref on runtime suspend Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation") removed most users of the platform device driver data from the qcom-qmp-usb driver, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. This bug was later reproduced when the driver was copied to create the qmp-usbc driver. Restore the driver data initialisation at probe to avoid a NULL-pointer dereference on runtime suspend. Apparently no one uses runtime PM, which currently needs to be enabled manually through sysfs, with these drivers.

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2024-50238 since 10/21/2024. There are neither technical details nor an exploit publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 216493 (Ubuntu 24.10 : Linux kernel vulnerabilities (USN-7276-1)), which helps to determine the existence of the flaw in a target environment.
