CVE-2026-56797

Dell Command Update (DCU) versions prior to 5.7.1 contain a TOCTOU race condition exploitable by a low-privileged local attacker, leading to elevation of privileges (CVSS 7.3 HIGH). No exploitation details are provided. Upgrade to DCU 5.7.1 or later as referenced in Dell DSA-2026-309.

CVE-2026-49415

During execve2 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...

CVE-2026-72338

A flaw was found in the Linux kernel's net/sched: actpedit component. A Time-of-check to time-of-use TOCTOU race condition exists when sizing and filling a flowrule buffer. This vulnerability allows a local attacker with CAPNETADMIN capabilities to perform a heap out-of-bounds write with controll...

CVE-2026-75856 CodeWhale before 0.8.64 SSRF Bypass via DNS Pinning TOCTOU

CodeWhale before 0.8.64 contains a server-side request forgery bypass vulnerability in DNS pinning logic that fails to prevent time-of-check-time-of-use attacks. Attackers can manipulate DNS responses to fail initial resolution checks and succeed on secondary requests, allowing requests to intern...

CVE-2026-74546

CVE-2026-74546 affects the Linux kernel hwmon adt7470 driver. A TOCTOU race can occur if fan data becomes 0 between the FAN_DATA_VALID() check and the FAN_PERIOD_TO_RPM() conversion, causing a divide-by-zero crash. The issue is mitigated by reading fan data once to prevent a concurrent update fro...

CVE-2026-74546

In the Linux kernel, the following vulnerability has been resolved: hwmon: adt7470 Fix divide-by-zero TOCTOU crash in fan speed read If the fan data becomes 0 between the FANDATAVALID check and the FANPERIODTORPM conversion, it will result in a divide-by-zero crash due to a race with a concurrent...
