High [CVE-2026-16524] PCP linux_sockets PMDA: Arbitrary Command Execution via Command Injection
A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh. This flaw is rated as Important because it allows a local attacker to achieve arbitrary command execution as the PMDA process user within the Performance Co-Pilot (PCP) environment. Exploitation requires the `linux_sockets` PMDA to be loaded and the `ss` utility to be present, which are common configurations. The vulnerability stems from an inverted validation logic in the `sockets_check_filter()` function, enabling the injection of malicious shell metacharacters into a filter value that is later executed. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-78. Affected products named by the advisory: Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On; Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support; and 9 more.
