CVE-2018-5873: An issue was discovered in the __ns_get_path function in fs/nsfs.c in the Linux kernel before 4.11.

An issue was discovered in the __ns_get_path function in fs/nsfs.c in the Linux kernel before 4.11. Due to a race condition when accessing files, a Use After Free condition can occur. This also affects all Android releases from CAF using the Linux kernel (Android for MSM, Firefox OS for MSM, QRD Android) before security patch level 2018-07-05.

Security readout for executives and security teams

CVE-2018-5873 is a Linux kernel namespace-filesystem race condition that can cause use-after-free memory corruption. It affects Linux kernels before 4.11 and CAF-based Android releases before the 2018-07-05 security patch level. Business urgency is highest for legacy mobile or embedded assets still running those builds. Exposure is most likely in older Linux systems, Android for MSM, Firefox OS for MSM, and QRD Android builds derived from CAF kernels that predate the referenced fixes or the 2018-07-05 Android security patch level. Prioritize if the organization still operates legacy Qualcomm Android, embedded, or unmanaged Linux assets. For current supported systems, this is mainly a verification item unless inventory shows pre-4.11 kernels or pre-2018-07-05 CAF Android builds. Mitigation focus: Update affected Linux kernels to a version containing the upstream fix.; Apply vendor Android or CAF builds at security patch level 2018-07-05 or later.; Confirm Qualcomm device firmware incorporates the referenced CAF kernel commit..
