Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-613 advisory.

In the Linux kernel, the following vulnerability has been resolved:

inet: inet_defrag: prevent sk release while still in use (CVE-2024-26921)

In the Linux kernel, the following vulnerability has been resolved:

af_unix: Fix garbage collector racing against connect() (CVE-2024-26923)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path

The commit mutex should not be released during the critical sectionbetween nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GCworker could collect expired objects and get the released commit lockwithin the same GC sequence.

nf_tables_module_autoload() temporarily releases the mutex to loadmodule dependencies, then it goes back to replay the transaction again.Move it at the end of the abort phase after nft_gc_seq_end() is called.
