CVE-2024-50099 affects Linux kernel ARM64 uprobe handling of LDR (literal) and LDRSW (literal) instructions. The simulate_ldr_literal() and simulate_ldrsw_literal() functions were reused from kprobes without adapting their privileged plain C memory accesses for user memory. These accesses lack exception-table entries, so faults trigger a kernel BUG(), terminating the kernel thread and potentially causing a lockup or panic. Hardware or software Privileged Access Never (PAN) causes the simulated user-memory accesses to fault whenever either mechanism is enabled. Address wrapping also theoretically permits access to a limited kernel virtual-address range, although contemporary kernels reserve that region and accesses fault. The fix rejects uprobes on these instructions while preserving their kprobe support.

An ARM64 Linux kernel vulnerability involving unsafe simulation of LDR (literal) and LDRSW (literal) instructions through uprobes. Unprotected accesses to user memory from kernel context can cause faults, terminate a kernel thread, and potentially cause a lockup or panic. The reference rates it Medium, with a CVSS v3 score of 5.5, requiring local access and low privileges and primarily affecting availability. The fix rejects uprobes on these instructions while retaining their simulation for kprobes. The Google Container-Optimized OS advisory recommends updating sys-kernel/lakitu-kernel-6_1 and related packages to version 18613.75.60 or later.
