| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2026-4878 | A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation. | [email protected] | 6.7 | 0.19% | 2026-04-09 | 2026-06-18 |
| CVE-2023-2603 | A vulnerability was found in libcap. This issue occurs in the _libcap_strdup() function and can lead to an integer overflow if the input string is close to 4GiB. | [email protected] | 7.8 | 0.57% | 2023-06-06 | 2026-06-17 |
| CVE-2023-2602 | A vulnerability was found in the pthread_create() function in libcap. This issue may allow a malicious actor to use cause __real_pthread_create() to return an error, which can exhaust the process memory. | [email protected] | 3.3 | 0.35% | 2023-06-06 | 2026-06-17 |
