CVE ID :CVE-2026-58100
Published : Oct. 15, 2026, 7:18 a.m. | 30 minutes ago
Description :kqueue_fork_copy_knote() indexed into the child's file descriptor table using a knote's file descriptor number without a bounds check. Because the child's table is copied before knotes are transferred, a concurrent thread in the parent could grow the parent's table and register knotes with file descriptor numbers beyond the end of the child's table, causing an out-of-bounds read. An unprivileged local user may be able to exploit these races to escalate privileges.
Severity: 0.0 | NA
