IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to overwrite critical files and obtain sensitive information due to a time-of-check to time-of-use (TOCTOU) race condition.

Secure BootROM of RK3588s SoC is vulnerable to a time-of-check to time-of-use attack in case of booting from external media (SPI NOR or NAND, EMMC or SD). The code reads the header of the next-stage loader twice. The header contains hashes of the executable modules and is signed with a private key, the public part of which is verified against the SHA256 digest blown in the OTP. The first read is only partial and contains only the hashes of the executable modules. The second is complete, including the header signature. Although the header is verified based on the fully read data, the authenticity of the executable modules is checked against the partial data from the first read. An attacker with physical access to a device containing RK3588s SoC can easily modify the next-stage loader data on-the-fly using a low-cost SD-card or SPI NOR/NAND or EMMC emulator. Even a simple ultra low-cost circuit comprising two memory chips (containing the same data but different headers - the original and the modified one) and a multiplexer can be used to carry out an attack. This can lead to arbitrary code execution with the highest privileges available (EL3). This issue affects RK3588s: RK3588s SoC BootROM (secure) 350B20210512V100 and possibly others. As remediation apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable https://www.rock-chips.com/a/en/products/RK35_Series/2022/0926/1660.html

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to cause a denial of service and compromise data integrity due to a time-of-check time-of-use race condition.

Dell Command Update (DCU), versions prior to 5.7.1, a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

Dell Command Update (DCU), versions prior to 5.7.1, contain a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

During execve(2) of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging permission check still saw the original credentials. An unprivileged local user can exploit this race to modify the address space of a SUID binary before its credentials are elevated, potentially gaining full control of the affected system.

Race condition in USB in Google Chrome prior to 151.0.7922.169 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)

n8n is an open source workflow automation platform. Prior to 1.123.64, 2.29.8, and 2.30.1, the Git node clone operation allows an authenticated workflow user to swap a validated directory for a symlink before cloning, planting a crafted repository in the community node directory that loads as a custom JavaScript node after restart and executes arbitrary code on the server. This issue is fixed in versions 1.123.64, 2.29.8, and 2.30.1.

Budibase is an open-source low-code platform. Prior to 3.40.0, packages/backend-core/src/utils/outboundFetch.ts pinned a validated address through a Node agent, but the REST integration used getDispatcher from packages/backend-core/src/utils/fetch.ts, causing undici to ignore that agent and resolve the hostname again. A builder could use DNS rebinding to make packages/server/src/integrations/rest.ts connect to an internal address after a public address passed validation, with full response access and arbitrary REST methods. The fix adds createPinnedLookup support to the undici dispatcher and passes the validated address to custom fetch implementations. This issue is fixed in version 3.40.0.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to gain unauthorized access to system objects due to a time-of-check to time-of-use (TOCTOU) race condition involving symbolic links.

The userspace syscall verifiers z_vrfy_zsock_sendmsg() and z_vrfy_zsock_recvmsg() in subsys/net/lib/sockets/sockets.c snapshot the caller-supplied struct net_msghdr into a kernel-side copy with k_usermode_from_copy(), but then re-read the still-live user struct for subsequent decisions. The kernel iovec shadow buffer is sized from one read of msg->msg_iovlen, while the population loop is bounded by a second, live read of the same field. Because msg points into ordinary user memory, a cooperating second thread in the same memory domain can inflate msg->msg_iovlen in the window between the sizing read and the loop test (a classic double-fetch / TOCTOU). The population loop then iterates past the number of net_iovec slots actually allocated, writing attacker-influenced iov_base/iov_len values beyond the end of the kernel-heap shadow buffer. The recvmsg verifier has the same defect on both its inbound and result write-back loops. The code is reachable from an unprivileged user thread whenever CONFIG_USERSPACE is enabled and the zsock_sendmsg/zsock_recvmsg syscalls are available. A successful race corrupts kernel-managed heap memory across the user-to-kernel privilege boundary, yielding a local privilege-escalation primitive or, at minimum, a kernel-fault denial of service. The fix copies the header once and derives every size, bound, and gate from the snapshot, copying each iovec entry atomically so its base and length can no longer be raced apart.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: avoid rereading IB param length Reuse the parameter length returned by vcn_v4_0_enc_find_ib_param() instead of rereading it from the IB. This avoids a potential TOCTOU issue if the IB contents change between reads. (cherry picked from commit dbb02b4755f8c1f3773263f2d779872c1c0c073a)

A time-of-check/time-of-use (TOCTOU) race condition in fastschema through v0.15.1 allows an unauthenticated remote attacker to bypass the OTP attempt limit on the account recovery flow, enabling brute-force attacks on 6-digit OTP codes.
