CVE-2026-64165 · Published 2026-07-19 · Updated 2026-07-19

Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ARM integrator early initialization process. The intcp init early() function calls syscon regmap lookup by compatible(), which subsequently triggers of syscon register(). Because of syscon register() attempts to allocate memory before the memory management subsystem has been initialized, the operation fails. Depending on the compiler version used (specifically observed with gcc 10.x, 11.x, and 13.x), this results in either a kernel NULL pointer dereference leading to a system crash or the return of an -ENOMEM error, which prevents sched clock register() from being called.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
