CVE-2026-19280: CWE-787 Out-of-bounds Write
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a denial of service as a result of a buffer overflow in a PASE process. An authenticated attacker could leverage this to terminate their own process.
AI Analysis
Technical Summary
IBM i versions 7.3 through 7.6 contain a buffer overflow vulnerability (CWE-787) in a PASE process. This flaw can be exploited by an authenticated attacker with low privileges to cause a denial of service by terminating their own process. The CVSS 3.1 base score is 5.2, reflecting local attack vector, low complexity, low privileges required, no user interaction, and impact on integrity and availability but not confidentiality.
Potential Impact
The vulnerability allows an authenticated attacker to cause denial of service by terminating their own process, impacting system availability and integrity. There is no impact on confidentiality. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, restrict access to trusted users and monitor for unusual process terminations related to PASE processes.
