  "details": "CVE-2026-4878. A flaw was found in libcap. A local unprivileged user can\nexploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the\n`cap_set_file()` function. This allows an attacker with write access to\na parent directory to redirect file capability updates to an\nattacker-controlled file. By doing so, capabilities can be injected into\nor stripped from unintended executables, leading to privilege\nescalation.\n",
