| filelock is a platform-independent file lock for Python. In versions prior to 3.20.1, a Time-of-Check-Time-of-Use (TOCTOU) race condition allows local attackers to corrupt or truncate arbitrary user files through symlink attacks. The vulnerability exists in both Unix and Windows lock file creation where filelock checks if a file exists before opening it with O_TRUNC. An attacker can create a symlink pointing to a victim file in the time gap between the check and open, causing os.open() to follow the symlink and truncate the target file. All users of filelock on Unix, Linux, macOS, and Windows systems are impacted. The vulnerability cascades to dependent libraries. The attack requires local filesystem access and ability to create symlinks (standard user permissions on Unix; Developer Mode on Windows 10+). Exploitation succeeds within 1-3 attempts when lock file paths are predictable. The issue is fixed in version 3.20.1. If immediate upgrade is not possible, use SoftFileLock instead of UnixFileLock/WindowsFileLock (note: different locking semantics, may not be suitable for all use cases); ensure lock file directories have restrictive permissions (chmod 0700) to prevent untrusted users from creating symlinks; and/or monitor lock file directories for suspicious symlinks before running trusted applications. These workarounds provide only partial mitigation. The race condition remains exploitable. Upgrading to version 3.20.1 is strongly recommended. |
| A Time-of-check time-of-use (TOCTOU) race condition in the AMD Secure Processor (ASP) could allow an attacker to modify External Global Memory Interconnect Trusted Agent (XGMI TA) commands as they are processed potentially resulting in loss of confidentiality, integrity, or availability. |
| A Time-of-check time-of-use (TOCTOU) race condition in the AMD Secure Processor (ASP) could allow an attacker to corrupt memory resulting in loss of integrity, confidentiality, or availability. |
| Anti-tampering protection of the Zscaler Client Connector can be bypassed under certain conditions when running the Repair App functionality. This affects Zscaler Client Connector on Windows prior to 4.2.1

| Memory corruption may occur while processing message from frontend during allocation. |
| Memory corruption may occur in keyboard virtual device due to guest VM interaction. |
| VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. |

| Memory corruption when blob structure is modified by user-space after kernel verification. |
| Memory corruption occurs during the copying of read data from the EEPROM because the IO configuration is exposed as shared memory. |
| Time-of-check time-of-use (toctou) race condition in Windows Fundamentals allows an authorized attacker to execute code over a network. |
| Time-of-check time-of-use (toctou) race condition in Windows Virtual Machine Bus allows an unauthorized attacker to execute code locally. |

| In the Linux kernel, the following vulnerability has been resolved:
posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()
If an exiting non-autoreaping task has already passed exit_notify() and
calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent
or debugger right after unlock_task_sighand().
If a concurrent posix_cpu_timer_del() runs at that moment, it won't be
able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or
lock_task_sighand() will fail.
Add the tsk->exit_state check into run_posix_cpu_timers() to fix this.
This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because
exit_task_work() is called before exit_notify(). But the check still
makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail
anyway in this case. |
| Memory corruption while submitting blob data to kernel space though IOCTL. |
| Memory corruption when using Virtual cdm (Camera Data Mover) to write registers. |
| Time-of-check time-of-use (toctou) race condition in Windows Subsystem for Linux allows an authorized attacker to elevate privileges locally. |
| Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier are affected by a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability that could result in a security feature bypass. An attacker could exploit this vulnerability by manipulating the timing between the check of a resource's state and its use, allowing unauthorized write access. Exploitation of this issue does not require user interaction. |
| Time-of-check time-of-use (toctou) race condition in Windows TCP/IP allows an authorized attacker to elevate privileges locally. |
