2024-05-23: CVE-2024-26923 was added to this 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.
(CVE-2024-26925)

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

smb: client: fix potential UAF in cifs_debug_files_proc_show() (CVE-2024-26928)

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

xen-netfront: Add missing skb_mark_for_recycle (CVE-2024-27393)

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

smb: client: fix potential UAF in cifs_signal_cifsd_for_reconnect() (CVE-2024-35861)

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

smb: client: fix potential UAF in smb2_is_valid_lease_break() (CVE-2024-35864)

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

erspan: make sure erspan_base_hdr is present in skb->head (CVE-2024-35888)

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

block: prevent division by zero in blk_rq_stat_sum() (CVE-2024-35925)

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

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