Time-of-check Time-of-use (TOCTOU) Race Condition

A race condition exists in the Falcon sensor for Windows that could allow an attacker, with the prior ability to execute code on a host, to delete arbitrary files. CrowdStrike released a security fix for this issue in Falcon sensor for Windows versions 7.24 and above and all Long Term Visibility (LTV) sensors. There is no indication of exploitation of these issues in the wild. Our threat hunting and intelligence team are actively monitoring for exploitation and we maintain visibility into any such attempts. The Falcon sensor for Mac, the Falcon sensor for Linux and the Falcon sensor for Legacy Systems are not impacted by this. CrowdStrike was made aware of this issue through our HackerOne bug bounty program. It was discovered by Cong Cheng and responsibly disclosed.Show less

Race condition in the Zoom Workplace VDI Plugin macOS Universal installer for VMware Horizon before version 6.4.10 (or before 6.2.15 and 6.3.12 in their respective tracks) may allow an authenticated user to conduct a disclosure of information via network access.Show less

In the Linux kernel, the following vulnerability has been resolved: media: rainshadow-cec: fix TOCTOU race condition in rain_interrupt() In the interrupt handler rain_interrupt(), the buffer full check on rain->buf_len is performed before acquiring rain->buf_lock. This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition, as rain->buf_len is concurrently accessed and modified in the work handler rain_irq_work_handler() under the same lock. Multiple interrupt invocations can race, with each reading buf_len before it becomes full and then proceeding. This can lead to both interrupts attempting to write to the buffer, incrementing buf_len beyond its capacity (DATA_SIZE) and causing a buffer overflow. Fix this bug by moving the spin_lock() to before the buffer full check. This ensures that the check and the subsequent buffer modification are performed atomically, preventing the race condition. An corresponding spin_unlock() is added to the overflow path to correctly release the lock. This possible bug was found by an experimental static analysis tool developed by our team.Show less

Race Condition in the Directory Validation Logic in the TeamViewer Full Client and Host prior version 15.69 on Windows allows a local non-admin user to create arbitrary files with SYSTEM privileges, potentially leading to a denial-of-service condition, via symbolic link manipulation during directory verification.Show less

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.Show less

Time-of-check Time-of-use race condition for some Intel(R) Connectivity Performance Suite software installers before version 40.24.11210 may allow an authenticated user to potentially enable escalation of privilege via local access.Show less

NVIDIA .run Installer for Linux and Solaris contains a vulnerability where an attacker could use a race condition to escalate privileges. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, denial of service, or data tampering.Show less
