Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> riscv: Sanitize syscall table indexing under speculation<br /> <br /> The syscall number is a user-controlled value used to index into the<br /> syscall table. Use array_index_nospec() to clamp this value after the<br /> bounds check to prevent speculative out-of-bounds access and subsequent<br /> data leakage via cache side channels.
