 It was discovered that HPLIP did not properly handle certain data, which could result in an out-of-bounds write. An attacker could possibly use this issue to cause a denial of service, expose sensitive information or execute arbitrary code. (CVE-2026-91097)

 It was discovered that HPLIP did not properly handle certain input, which could result in a heap-based buffer overflow. An attacker could possibly use this issue to cause a denial of service, expose sensitive information or execute arbitrary code. (CVE-2026-91098)

 It was discovered that HPLIP created certain files with insecure permissions. An attacker could possibly use this issue to expose or modify sensitive information. (CVE-2026-91099)

 It was discovered that HPLIP did not properly handle certain input while issuing an OS command. An attacker could possibly use this issue to execute arbitrary commands. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2026-91100)

 It was discovered that HPLIP did not properly validate certain array indices. An attacker could possibly use this issue to cause a denial of service, expose sensitive information or execute arbitrary code.
 (CVE-2026-91101)

 It was discovered that HPLIP did not properly handle certain input while issuing an OS command. An attacker could possibly use this issue to execute arbitrary commands. (CVE-2026-91102)

 It was discovered that HPLIP did not properly handle certain numeric values, which could result in an integer underflow. An attacker could possibly use this issue to cause a denial of service, expose sensitive information or execute arbitrary code. (CVE-2026-91103)

 It was discovered that HPLIP did not properly handle certain input, which could result in a heap-based buffer overflow. An attacker could possibly use this issue to cause a denial of service, expose sensitive information or execute arbitrary code. (CVE-2026-91104, CVE-2026-91105, CVE-2026-91106)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
