Original Description n8n before 1.123.64, 2.29.8, and 2.30.1 contains a TOCTOU race condition in the Git node's clone operation that allow...
acl: TOCTOU Symlink Traversal via getfacl/setfacl
A time-of-check to time-of-use TOCTOU race condition vulnerability was found in acl. By replacing a pathname component with a symbolic link between a security check and subsequent file operations, an attacker can redirect file access control list operations. This occurs when privileged processes...
CVE-2026-64034
A flaw was found in the Linux kernel's mana network driver. This Time-of-Check to Time-of-Use TOCTOU vulnerability allows a hardware component to modify a message identifier hwcmsgid in Direct Memory Access DMA memory after it has been validated but before it is used. This manipulation bypasses...
ALSA-2026:43420 Important: acl security update
Access Control Lists ACLs are used to define fine-grained discretionary access rights for files and directories. The acl packages contain the getfacl and setfacl utilities needed for manipulating access control lists. Security Fixes: acl: Symlink traversal privilege escalation via libacl function...
GHSA-GX3V-Q759-G323 Gitea: TOTP TOCTOU race on web 2FA paths + missing replay check on Basic-Auth `X-Gitea-OTP` surface
Summary I'm reporting two related TOTP one-time-use defects in Gitea that survive the CVE-2021-45331 fix. The 2018 fix PR 3878 introduced the TwoFactor.LastUsedPasscode field and added an in-memory inequality check on the web 2FA login path. That check works correctly in the single-request case,...

EUVD-2026-45776
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix TOCTOU race for reported vlans The local TT based TVLV is generated by first checking the number of VLANs which have at least one TT entry. A new buffer with the correct size for the VLANs is then allocated...
CVE-2026-64034
The CVE concerns the Linux kernel net: mana TOCTOU in hwc_msg_id handling. In mana_hwc_rx_event_handler(), resp->response.hwc_msg_id is read from DMA-coherent memory and bounds-checked, then mana_hwc_handle_resp() re-reads the same field from the same DMA buffer for test_bit() and pointer arit...
