CVE-2026-90094: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: arm64: process: Fix context switching MTE store-only tag check SCTLR_EL1.TCSO0 is set when user opt-in for MTE store-only tag check mode. However, it is not part of SCTLR_USER_MASK which imply that on context switch we never clear SCTLR_EL1.TCSO0, so we are leaking that setting into another task. Fix that by including SCTLR_EL1_TCSO0_MASK into SCTLR_USER_MASK
