Memory Corruption
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
How It Works
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space. Attackers exploit these flaws by carefully crafting inputs that trigger the corruption, allowing them to overwrite critical data structures like function pointers, return addresses, or object metadata. The corrupted memory then causes the program to execute attacker-controlled code or leak sensitive information when that memory is subsequently accessed.
Several common variants exist with distinct mechanisms. Buffer overflows write past array boundaries, overwriting adjacent memory. Use-after-free bugs occur when code accesses memory after it's been deallocated, allowing attackers to reallocate that space with malicious data. Type confusion tricks programs into treating objects as different types, causing field accesses at incorrect offsets that can leak data or enable writes to arbitrary locations. Double-free vulnerabilities free the same memory twice, corrupting heap metadata structures that allocate memory, ultimately enabling arbitrary writes when the corrupted allocator is used again.
The typical attack flow involves reconnaissance to identify the corruption primitive, heap manipulation to position target structures in predictable locations, triggering the vulnerability to corrupt specific memory, and finally leveraging the corruption to hijack control flow or extract data. Modern exploits often chain multiple primitives together, using information leaks to defeat ASLR before achieving code execution.
Impact
- Arbitrary code execution: Execute attacker-supplied machine code or reuse existing code (ROP/JOP) with full privileges of the vulnerable process
- Privilege escalation: Exploit kernel memory corruption to escalate from user to root/SYSTEM privileges
- Information disclosure: Leak cryptographic keys, passwords, authentication tokens, or bypass ASLR by reading memory layout
- Denial of service: Crash critical services by corrupting essential data structures
- Sandbox escape: Break out of browser or application isolation boundaries to compromise the host system
Real-World Examples
The Chrome V8 JavaScript engine has suffered numerous type confusion vulnerabilities where JavaScript objects are mishandled, allowing attackers to achieve browser compromise through malicious websites. CVE-2021-30551 exemplified this, enabling remote code execution via crafted web content.
Windows kernel vulnerabilities like CVE-2020-17087 demonstrated use-after-free exploitation, where local attackers triggered memory reuse in the kernel to escalate privileges to SYSTEM. This was actively exploited in targeted attacks before patching.
The Heartbleed vulnerability (CVE-2014-0160) in OpenSSL showed devastating information disclosure through a buffer over-read, leaking 64KB chunks of server memory containing private keys, passwords, and session tokens across millions of servers.
Mitigation
- Memory-safe languages: Use Rust, Go, or Swift for new code to eliminate entire classes of corruption bugs
- Sanitizers in development: Deploy AddressSanitizer (ASAN) and MemorySanitizer (MSAN) during testing to detect corruption immediately
- Fuzzing with coverage feedback: Continuously fuzz parsers and input handlers using AFL++ or libFuzzer to discover corruption bugs
- Control Flow Integrity (CFI): Enable compiler-based CFI to restrict indirect call targets and prevent ROP
- Exploit mitigations: Deploy stack canaries, ASLR, DEP/NX, and shadow stacks on all platforms
- Sandboxing: Isolate vulnerable components using seccomp, pledge, or process isolation to contain successful exploits
Recent CVEs (15306)
Use-after-free vulnerability in Linux kernel's Cadence MAC (macb) driver allows local attackers to read freed memory via ethtool get_ts_info calls on PTP-capable network interfaces. The PTP clock is registered when the interface opens and destroyed when it closes, but the ethtool handler can still access it after deallocation, causing a kernel memory access violation. No active exploitation confirmed; patch available in stable kernel releases.
Use-after-free vulnerability in Linux kernel SPI controller registration allows local attackers to trigger unclocked register accesses and potential information disclosure when per-CPU statistics allocation fails during controller initialization. The vulnerability affects all Linux kernel versions and is fixed via proper driver core deregistration on allocation failure; no CVSS score or active exploitation data available at time of analysis.
Use-after-free vulnerability in the Linux kernel's Bluetooth HIDP subsystem allows local attackers to trigger a kernel crash or potentially execute arbitrary code by failing to properly release L2CAP connection references when user callbacks are invoked. The flaw affects all Linux kernel versions in the CPE range and has been resolved through reference counting fixes in the L2CAP connection cleanup path; no public exploit code is currently identified, but the vulnerability requires local access to trigger via Bluetooth device manipulation.
Use-after-free in Linux kernel Bluetooth L2CAP layer allows local attackers to cause denial of service or potentially execute code via a race condition in l2cap_unregister_user(). The vulnerability arises because l2cap_register_user() and l2cap_unregister_user() access conn->users without proper locking (conn->lock), while l2cap_conn_del() protects the same structure with conn->lock, creating concurrent access to freed memory. All Linux kernel versions with Bluetooth L2CAP support are affected. Patch available via Linux stable kernel commits.
Use-after-free in Linux kernel netfilter ctnetlink module allows local attackers to read freed kernel memory by triggering multiple-round netlink dump operations on conntrack expectations, exploiting improper reference counting in ctnetlink_dump_exp_ct() that drops conntrack references before the dump callback completes. The vulnerability requires local network namespace access and CAP_NET_ADMIN capability but enables information disclosure of kernel heap contents via KASAN-detected slab-use-after-free on ct->ext dereference.
Use-after-free in Linux kernel MANA hardware channel teardown (net/mana driver) allows concurrent interrupt handlers to dereference freed memory in mana_hwc_destroy_channel(), potentially causing NULL pointer dereference or memory corruption. The vulnerability stems from improper teardown ordering where hwc->caller_ctx is freed before CQ/EQ IRQ handlers are fully synchronized, affecting all Linux kernel versions with the MANA driver. Fixes are available across stable kernel branches via upstream commit reordering.
NULL dereference and use-after-free in the Linux kernel's SMC (Shared Memory Communications) socket implementation occur when smc_tcp_syn_recv_sock() races with socket close operations, allowing a local attacker to trigger a kernel panic via concurrent manipulation of TCP SYN handling and SMC listen socket closure. The vulnerability affects the Linux kernel across multiple versions via the net/smc subsystem and is addressed through RCU-protected access and refcount validation rather than lock-based serialization.
A use-after-free vulnerability in the Linux kernel's mshv (Microsoft Hyper-V) driver allows local attackers to trigger a kernel panic by unmapping user memory after a failed mshv_map_user_memory() call. The error path incorrectly calls vfree() without unregistering the associated MMU notifier, leaving a dangling reference that fires when userspace performs subsequent memory operations. This is a memory safety issue affecting the Hyper-V virtualization subsystem in the Linux kernel.
Use-after-free in Linux kernel ksmbd SMB server allows local or remote attackers to read freed memory and potentially achieve denial of service or code execution via compound SMB2 requests that reuse a tree connection after it has been disconnected and its associated share_conf structure freed. The vulnerability exists because smb2_get_ksmbd_tcon() bypasses state validation checks when reusing connections in compound requests, enabling subsequent commands to dereference already-freed share_conf pointers. No CVE severity metrics are available, but KASAN confirms memory corruption is triggered in smb2_write operations during tree disconnect sequences.
Use-after-free in Linux kernel's ksmbd SMB server allows remote attackers to crash the kernel or potentially execute code via malicious SMB2 DURABLE_REQ_V2 replay operations. The vulnerability occurs when parse_durable_handle_context() unconditionally reassigns file handle connection pointers during replay operations, causing stale pointer dereferences when the reassigned connection is subsequently freed. A KASAN report confirms the use-after-free in spin_lock operations during file descriptor closure, triggered during SMB2 connection handling in the ksmbd-io workqueue. No public exploit code or active exploitation has been confirmed at time of analysis.
