Description
In the Linux kernel, the following vulnerability has been resolved:
riscv: Sanitize syscall table indexing under speculation
The syscall number is a user-controlled value used to index into the
syscall table. Use array_index_nospec() to clamp this value after the
bounds check to prevent speculative out-of-bounds access and subsequent
data leakage via cache side channels.
Affected configurations
• linux linux kernel (>= 6.4 < 6.12.70)
• linux linux kernel (>= 6.13 < 6.18.10)
• linux linux kernel 6.19
