CVE-2026-43317 Details
Description
In the Linux kernel, the following vulnerability has been resolved: most: core: fix leak on early registration failure A recent commit fixed a resource leak on early registration failures but for some reason left out the first error path which still leaks the resources associated with the interface. Fix up also the first error path so that the interface is always released on errors.
A resource leak vulnerability has been identified in the Linux kernel's MOST core driver. This issue arises during the early registration of interfaces, where certain error paths fail to release allocated resources, leading to a leak. The vulnerability affects the Linux kernel stable tree.
Users can apply the latest patch available in the Linux kernel stable tree to address this vulnerability.
