CVE-2026-45253 Missing validation in ptrace(PT_SC_REMOTE)

ptracePTSCREMOTE failed to properly validate parameters for the syscall2 and syscall2 meta-system calls. As a result, a user with the ability to debug a process may trigger arbitrary code execution in the kernel, even if the target process has no special privileges. The missing validation allows ...

CVE-2026-45250

The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the supplied list exceeds the capaci...

CVE-2026-45250

CVE-2026-45250 concerns a stack buffer overflow in the FreeBSD kernel arising from setcred(2). The unprivileged user can trigger a copyin into a fixed-size kernel-stack array before validating the number of supplementary groups, causing a stack overflow when the list is large. This allows an unpr...

Parser-Free Querying of Security Logs

Security analysts routinely query system logs to detect threats and investigate incidents, but each log source uses its own semi-structured format: logs are cheap to produce, but expensive to use. The standard approach, building per-source parsers to normalize logs into structured schemas, is...
