Issue summary: An uncommon configuration of clients performing DANE TLSA-based server authentication, when paired with uncommon server DANE TLSA records, may result in a use-after-free and/or double-free on the client side. Impact summary: A use after free can have a range of potential consequences such as the corruption of valid data, crashes or execution of arbitrary code. However, the issue only affects clients that make use of TLSA records with both the PKIX-TA(0/PKIX-EE(1) certificate usages and the DANE-TA(2) certificate usage. By far the most common deployment of DANE is in SMTP MTAs for which RFC7672 recommends that clients treat as 'unusable' any TLSA records that have the PKIX certificate usages. These SMTP (or other similar) clients are not vulnerable to this issue. Conversely, any clients that support only the PKIX usages, and ignore the DANE-TA(2) usage are also not vulnerable. The client would also need to be communicating with a server that publishes a TLSA RRset with both types of TLSA records. No FIPS modules are affected by this issue, the problem code is outside the FIPS module boundary.

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.

Use-after-free memory corruption in Electron framework (versions <39.8.1, <40.7.0, <41.0.0) allows unauthenticated remote attackers to potentially execute arbitrary code when offscreen rendering is enabled and child windows are permitted. The vulnerability triggers when a parent offscreen WebContents is destroyed while child windows remain active, causing subsequent paint operations to dereference freed memory. EPSS data not available; no public exploit identified at time of analysis. Fixed versions released by vendor.

Use-after-free in Electron framework allows memory corruption when native save-file dialogs remain open during session teardown. Affected Electron versions prior to 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.7 enable local attackers with UI interaction to trigger freed memory dereference via downloaded files, potentially causing application crashes or memory corruption. Only applications that programmatically destroy sessions at runtime and permit downloads are vulnerable; no public exploit code or active exploitation has been identified.

Use-after-free in Electron framework allows memory corruption when handling fullscreen, pointer-lock, or keyboard-lock permission requests in apps with asynchronous `session.setPermissionRequestHandler()` callbacks. Affects npm package electron versions prior to 41.0.0-beta.8, 40.7.0, 39.8.0, and 38.8.6. Remote attackers can trigger memory corruption or crashes if the requesting frame navigates or window closes while the permission handler is pending. EPSS data not available; no public exploit identified at time of analysis. Vendor-released patches available across all affected major version branches.

Use-after-free in Electron's powerMonitor module allows local attackers to trigger memory corruption or application crashes through system power events. All Electron applications (versions <38.8.6, <39.8.1, <40.8.0, <41.0.0-beta.8) that subscribe to powerMonitor events (suspend, resume, lock-screen) are vulnerable when garbage collection frees the PowerMonitor object while OS-level event handlers retain dangling pointers. Exploitation requires local access and specific timing conditions (CVSS 7.0 HIGH, AC:H). No public exploit identified at time of analysis, though the technical details are publicly documented in the GitHub security advisory.

Use-after-free vulnerability in Linux kernel futex handling allows local attackers to read freed memory via race condition between futex_key_to_node_opt() and vma_replace_policy(). When mbind() concurrently replaces virtual memory area policies, __futex_key_to_node() may dereference a freed mempolicy structure, enabling information disclosure of kernel memory. The vulnerability requires local access and precise timing but poses memory safety risk in multi-threaded applications using futex operations alongside memory policy changes.

Use-after-free in Linux kernel clsact qdisc initialization and destruction rollback allows local denial of service or potential information disclosure when qdisc replacement fails midway during tcf_block_get_ext() operations. The vulnerability stems from asymmetric initialization and cleanup paths where egress_entry references from a previous clsact instance remain valid during failure scenarios, leading to double-free or use-after-free conditions. Affected Linux kernel versions across all distributions that include the clsact traffic control qdisc require patching.

Use-after-free in Linux kernel netfilter BPF hook memory management allows local attackers to read sensitive kernel memory via concurrent nfnetlink_hooks dumping operations. The vulnerability arises from premature memory release in hook structures before RCU readers complete their access, enabling information disclosure through netlink interface. No active exploitation confirmed, but the KASAN report demonstrates reliable reproducer availability.
