Noroxi assessment

Priority: Monitor (action score 18/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.35% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: Azure Linux 3.0 ARM 9.0.2190-5; Azure Linux 3.0 x64 9.0.2190-5; CBL Mariner 2.0 ARM 9.0.2121-3.

Low priority for now. Upgrade to Azure Linux 3.0 ARM 9.0.2190-5; Azure Linux 3.0 x64 9.0.2190-5; CBL Mariner 2.0 ARM 9.0.2121-3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The UNIX editor Vim prior to version 9.1.0678 has a use-after-free error in argument list handling. When adding a new file to the argument list, this triggers `Buf*` autocommands. If in such an autocommand the buffer that was just opened is closed (including the window where it is shown), this causes the window structure to be freed which contains a reference to the argument list that we are actually modifying. Once the autocommands are completed, the references to the window and argument list are no longer valid and as such cause an use-after-free. Impact is low since the user must either intentionally add some unusual autocommands that wipe a buffer during creation (either manually or by sourcing a malicious plugin), but it will crash Vim. The issue has been fixed as of Vim patch v9.1.0678.
