Use After Free

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.

Curl's SMB implementation contains a use-after-free vulnerability that causes denial of service when processing consecutive requests to the same host, as the library incorrectly dereferences freed memory on subsequent connections. Public exploit code exists for this vulnerability affecting Curl installations. An attacker can crash Curl-based applications or services by triggering multiple SMB requests, though remote code execution is not possible due to the nature of the memory corruption.

Arbitrary code execution in Adobe Acrobat and Acrobat Reader versions 24.001.30307 and earlier stems from a use-after-free memory vulnerability triggered when users open specially crafted files. An attacker can achieve code execution with the privileges of the current user, though exploitation requires victim interaction. No patch is currently available for affected versions.

Arbitrary code execution in Adobe Acrobat Reader and Acrobat (versions 24.001.30307 and earlier) via a use-after-free vulnerability requires victims to open a malicious file. Local attackers can exploit this to execute code with the privileges of the current user. No patch is currently available.

Local privilege escalation on Android devices occurs through a race condition in the VPU driver's instance opening function, allowing attackers to trigger a use-after-free condition without requiring special privileges or user interaction. An unprivileged local attacker can exploit this vulnerability to gain elevated system privileges. No patch is currently available for this vulnerability.
