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

Attack requires local authenticated access with low complexity (CVSS AV:L/AC:L/PR:L), limiting remote exploitation scenarios.
In the Linux kernel, the following vulnerability has been resolved: usb: chipidea: udc: fix DMA and SG cleanup in _ep_nuke() The ChipIdea UDC driver can encounter "not page aligned sg buffer" errors when a USB device is reconnected after being disconnected during an active transfer. This occurs because _ep_nuke() returns requests to the gadget layer without properly unmapping DMA buffers or cleaning up scatter-gather bounce buffers. Root cause: When a disconnect happens during a multi-segment DMA transfer, the request's num_mapped_sgs field and sgt.sgl pointer remain set with stale values. The request is returned to the gadget driver with status -ESHUTDOWN but still has active DMA state. If the gadget driver reuses this request on reconnect without reinitializing it, the stale DMA state causes _hardware_enqueue() to skip DMA mapping (seeing non-zero num_mapped_sgs) and attempt to use freed/invalid DMA addresses, leading to alignment errors and potential memory corruption. The normal completion path via _hardware_dequeue() properly calls usb_gadget_unmap_request_by_dev() and sglist_do_debounce() before returning the request. The _ep_nuke() path must do the same cleanup to ensure requests are returned in a clean, reusable state. Fix: Add DMA unmapping and bounce buffer cleanup to _ep_nuke() to mirror the cleanup sequence in _hardware_dequeue(): - Call usb_gadget_unmap_request_by_dev() if num_mapped_sgs is set - Call sglist_do_debounce() with copy=false if bounce buffer exists This ensures that when requests are returned due to endpoint shutdown, they don't retain stale DMA mappings. The 'false' parameter to sglist_do_debounce() prevents copying data back (appropriate for shutdown path where transfer was aborted).
Out-of-bounds write in Linux kernel vhost_vdpa subsystem allows local authenticated users to achieve arbitrary kernel memory corruption via ASID group assignment. Affects Linux kernel versions 5.19 through 6.19.x, with vendor patches available for stable branches 6.12.75, 6.18.16, 6.19.6, and mainline 7.0.

Use-after-free in Linux kernel farsync driver allows remote code execution when FarSync T-series WAN cards are detached while tasklets remain active. The vulnerability occurs when fst_tx_task or fst_int_task continue executing after fst_card_info is freed in fst_remove_one(), causing the kernel to access deallocated memory. Despite the CVSS 8.8 score with network vector, the EPSS score is extremely low (0.02%, 7th percentile), suggesting minimal real-world exploitation likelihood. No active exploitation confirmed (not in CISA KEV). Patches available across multiple stable kernel versions (5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0).
Out-of-bounds memory access in Linux kernel RPS (Receive Packet Steering) subsystem allows remote unauthenticated attackers to trigger kernel crashes or potentially achieve code execution with SYSTEM privileges. The flaw stems from incorrect assumptions about RPS hash table sizing across receive queues, introduced in commit 48aa30443e52. Exploitation requires no authentication (CVSS AV:N/PR:N) but EPSS probability remains low at 0.02% (4th percentile), suggesting limited real-world targeting. Patches available for stable kernel branches 6.18.16, 6.19.6, and 7.0.
Out-of-bounds kernel memory write in Linux kernel's AMD KFD (Kernel Fusion Driver) allows local authenticated attackers with low privileges to escalate to root privileges. The kfd_event_page_set() function performs unchecked memset operations of fixed size (KFD_SIGNAL_EVENT_LIMIT * 8 bytes) regardless of user-supplied buffer size, enabling unprivileged userspace processes to corrupt kernel memory. Patches are available across multiple stable kernel branches (5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0). EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability despite high CVSS severity, likely due to the local attack vector and requirement for systems with AMD GPU hardware running the amdkfd driver.
In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: validate num_ifs to prevent out-of-bounds write The driver obtains sw_attr.num_ifs from firmware via dpsw_get_attributes() but never validates it against DPSW_MAX_IF (64). This value controls iteration in dpaa2_switch_fdb_get_flood_cfg(), which writes port indices into the fixed-size cfg->if_id[DPSW_MAX_IF] array. When firmware reports num_ifs >= 64, the loop can write past the array bounds. Add a bound check for num_ifs in dpaa2_switch_init(). dpaa2_switch_fdb_get_flood_cfg() appends the control interface (port num_ifs) after all matched ports. When num_ifs == DPSW_MAX_IF and all ports match the flood filter, the loop fills all 64 slots and the control interface write overflows by one entry. The check uses >= because num_ifs == DPSW_MAX_IF is also functionally broken. build_if_id_bitmap() silently drops any ID >= 64: if (id[i] < DPSW_MAX_IF) bmap[id[i] / 64] |= ...
Use-after-free in Linux kernel fore200e ATM driver allows local attackers to achieve high-severity impacts during PCA-200E or SBA-200E adapter removal. When the device is detached, tx_tasklet or rx_tasklet may still be running and access already-freed memory in fore200e_tx_tasklet() or fore200e_rx_tasklet(), potentially leading to code execution, information disclosure, or denial of service. Patches available across stable kernel branches (5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0). EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. Not listed in CISA KEV. Identified through static analysis, suggesting no active in-the-wild exploitation at time of disclosure.
Heap buffer overflow in Linux kernel's IPv6 IOAM (In-situ Operations, Administration, and Maintenance) packet processing allows remote unauthenticated attackers to corrupt kernel memory and trigger system crashes. Attackers send crafted IPv6 packets with inconsistent IOAM trace headers (nodelen=0 with type bits set), causing __ioam6_fill_trace_data() to write ~100 bytes beyond allocated memory into skb_shared_info structures. Despite CVSS 9.8 critical rating, EPSS exploitation probability is low (0.05%, 16th percentile) and no active exploitation or public POC has been identified. Vendor patches available across multiple stable kernel branches (5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0).
Out-of-bounds read in Linux kernel EROFS filesystem allows local attackers with user interaction to read kernel memory and cause denial of service via crafted compressed images. The vulnerability stems from incorrect classification of unaligned plain extents, triggering OOB access in z_erofs_transform_plain(). Vendor patches are available across multiple stable kernel branches (6.15, 6.18.16, 6.19.6, 7.0). EPSS score of 0.02% (4th percentile) indicates very low observed exploitation probability, with no active exploitation confirmed at time of analysis.
Memory corruption in Linux kernel XFS filesystem allows authenticated users with write access to trigger kernel assertion failures and system shutdowns via crafted extended attribute operations. The vulnerability stems from incorrect freemap adjustment logic when adding xattrs to leaf blocks, causing the entries array and free space tracking to claim overlapping memory regions. This results in firstused pointer corruption where the name area starts below the end of the entries array. Vendor-released patches are available across multiple stable kernel branches (5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0). Low EPSS score (0.02%, 7th percentile) and no CISA KEV listing indicate no widespread exploitation observed, though the high CVSS 8.8 reflects severe impact on availability and potential for data corruption in XFS filesystems.
Buffer overflow in Linux kernel's ARM CMN performance monitoring driver allows local attackers with low privileges to execute arbitrary code and gain elevated access. The perf/arm-cmn driver fails to validate hardware configuration parameters against assumed maximum sizes, enabling memory corruption through crafted CMN device configurations. While EPSS indicates low exploitation probability (0.02%), patches are available across all maintained kernel branches (6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0) per vendor advisories. The local attack vector and requirement for low-privileged user access limit remote exploitation scenarios.
In the Linux kernel, the following vulnerability has been resolved: reset: gpio: suppress bind attributes in sysfs This is a special device that's created dynamically and is supposed to stay in memory forever. We also currently don't have a devlink between it and the actual reset consumer. Suppress sysfs bind attributes so that user-space can't unbind the device because - as of now - it will cause a use-after-free splat from any user that puts the reset control handle.
Remote unauthenticated attackers can cause critical out-of-bounds writes in the Linux kernel's Distributed Lock Manager (DLM) subsystem by sending malformed network messages with unvalidated length parameters to dlm_dump_rsb_name(). When the length exceeds DLM_RESNAME_MAXLEN, dlm_search_rsb_tree() writes beyond allocated buffers, enabling arbitrary code execution, denial of service, or information disclosure. Patches available for kernel versions 6.12.75, 6.18.16, 6.19.6, and 7.0.
