An issue was discovered in illumos before f859e7171bb5db34321e45585839c6c3200ebb90, OmniOS Community Edition r151038, OpenIndiana Hipster 2021.04, and SmartOS 20210923. A local unprivileged user can cause a deadlock and kernel panic via crafted rename and rmdir calls on tmpfs filesystems. Oracle Solaris 10 and 11 is also affected.

This Solaris system is missing necessary patches to address a critical security update :

  - Vulnerability in the Oracle Solaris product of Oracle     Systems (component: Filesystem). Supported versions that     are affected are 11 and 10. Easily exploitable     vulnerability allows low privileged attacker with logon     to the infrastructure where Oracle Solaris executes to     compromise Oracle Solaris. While the vulnerability is in     Oracle Solaris, attacks may significantly impact     additional products. Successful attacks of this     vulnerability can result in unauthorized ability to     cause a hang or frequently repeatable crash (complete     DOS) of Oracle Solaris. CVSS 3.1 Base Score 6.5     (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H).
    (CVE-2021-43395)

    (CVE-2021-43395)

  - Vulnerability in the Oracle Solaris product of Oracle     Systems (component: Kernel). The supported version that     is affected is 11. Easily exploitable vulnerability     allows low privileged attacker with logon to the     infrastructure where Oracle Solaris executes to     compromise Oracle Solaris. Successful attacks of this     vulnerability can result in unauthorized ability to     cause a hang or frequently repeatable crash (complete     DOS) of Oracle Solaris as well as unauthorized update,     insert or delete access to some of Oracle Solaris     accessible data. Note: This vulnerability applies to     Oracle Solaris on SPARC systems only. CVSS 3.1 Base     Score 6.1 (Integrity and Availability impacts). CVSS     Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H).
    (CVE-2021-2192)

  - Vulnerability in the Oracle Solaris product of Oracle     Systems (component: Install). The supported version that     is affected is 11. Easily exploitable vulnerability     allows low privileged attacker with logon to the     infrastructure where Oracle Solaris executes to     compromise Oracle Solaris. Successful attacks require     human interaction from a person other than the attacker.
    Successful attacks of this vulnerability can result in     unauthorized update, insert or delete access to some of     Oracle Solaris accessible data and unauthorized ability     to cause a partial denial of service (partial DOS) of     Oracle Solaris. CVSS 3.1 Base Score 3.9 (Integrity and     Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L).
