CVE-2024-58000

CVE-2024-58000 affects the Linux kernel Io_uring reg-wait path. The root cause is speculative execution on a kernel array indexed by user input when using ENTER_EXT_ARG_REG, which could interpret an offset into a pre-mapped memory region as an argument. The documented fix is to prevent speculativ...
