A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation (TLBI) operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local attacker to gain kernel privileges or a guest VM to escape to the hypervisor, resulting in complete system compromise.
Отчет
This is an Important flaw in the Linux kernel on ARM processors, allowing a local unprivileged attacker to achieve privilege escalation to kernel level or a guest virtual machine to escape to the hypervisor. The vulnerability stems from a race condition during Translation Lookaside Buffer Invalidation (TLBI) operations when memory permissions are altered, enabling writes to higher exception level resources.
