CVE-2025-38433

CVE-2025-38433 concerns a Linux kernel issue on riscv nommu kernels where the function __runtime_fixup_32 fails to handle a zero-valued upper 32 bits during patching, potentially producing garbage in the pointer’s upper half and causing a kernel panic when accessed. The fixed logic adjusts the co...
