CVE-2026-39461 select(2) file descriptor set overflow causes stack overflow

libcasper3 communicates with helper processes via UNIX domain sockets, and uses the select2 system call to wait for data to become available. However, it does not verify that its socket descriptor fits within select2's descriptor set size limit of FDSETSIZE 1024. An attacker able to cause an...

CVE-2026-39461

The CVE-2026-39461 issue affects libcasper(3), which communicates with helper processes over UNIX domain sockets and uses select(2) to wait for data. The problem is that it does not verify that its socket descriptor fits within FD_SETSIZE (1024), potentially allowing an application that opens man...

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...

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...
