CVE-2021-44142 – Samba fruit_pwrite Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44142
01 Feb 2022 — The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.

CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
25 Jan 2022 — A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfull... • https://packetstorm.news/files/id/166196 • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

CVE-2020-25719 – samba: Samba AD DC did not always rely on the SID and PAC in Kerberos tickets
https://notcve.org/view.php?id=CVE-2020-25719
10 Nov 2021 — A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.

CVE-2021-3656 – kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
https://notcve.org/view.php?id=CVE-2021-3656
09 Sep 2021 — A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the en... • https://github.com/rami08448/CVE-2021-3656-Demo • CWE-862: Missing Authorization •
