In the Linux kernel, the following vulnerability has been resolved:
mm: swap: fix race between free_swap_and_cache() and swapoff()
There was previously a theoretical window where swapoff() could run and
teardown a swap_info_struct while a call to free_swap_and_cache() was
running in another thread. This could cause, amongst other bad
possibilities, swap_page_trans_huge_swapped() (called by
free_swap_and_cache()) to access the freed memory for swap_map.
This is a theoretical problem and I haven't been able to provoke it from a
test case. But there has been agreement based on code review that this is
possible (see link below).
Fix it by using get_swap_device()/put_swap_device(), which will stall
swapoff(). There was an extra check in _swap_info_get() to confirm that
the swap entry was not free. This isn't present in get_swap_device()
because it doesn't make sense in general due to the race between getting
the reference and swapoff. So I've added an equivalent check directly in
free_swap_and_cache().
Details of how to provoke one possible issue (thanks to David Hildenbrand
for deriving this):
--8try_to_unuse() will stop as soon as soon as si->inuse_pages==0.
So the question is: could someone reclaim the folio and turn
si->inuse_pages==0, before we completed swap_page_trans_huge_swapped().
Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are
still references by swap entries.
Process 1 still references subpage 0 via swap entry.
Process 2 still references subpage 1 via swap entry.
Process 1 quits. Calls free_swap_and_cache().
-> count == SWAP_HAS_CACHE
[then, preempted in the hypervisor etc.]
Process 2 quits. Calls free_swap_and_cache().
-> count == SWAP_HAS_CACHE
Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls
__try_to_reclaim_swap().
__try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()->
put_swap_folio()->free_swap_slot()->swapcache_free_entries()->
swap_entry_free()->swap_range_free()->

CVE-2024-26960 [HIGH] Kernel Live Patch Security Notice
Title: Kernel Live Patch Security Notice
Summary: Several security issues were fixed in the kernel.
In the Linux kernel, the following vulnerability has been
resolved: tls: fix use-after-free on failed backlog decryption When the
decrypt request goes to the backlog and crypto_aead_decrypt returns -EBUSY,
tls_do_decryption will wait until all async decryptions have completed. If
one of them fails, tls_do_decryption will return -EBADMSG and
tls_decrypt_sg jumps to the error path, releasing all the pages. But the
pages have been passed to the async callback, and have already been
released by tls_decrypt_done. The only true async case is when
crypto_aead_decrypt returns -EINPROGRESS. With -EBUSY, we already waited so
we can tell tls_sw_recvmsg that the data is available for immediate copy,

CVE-2024-38630 Kernel Live Patch Security Notice
Title: Kernel Live Patch Security Notice
Summary: Several security issues were fixed in the kernel.
In the Linux kernel, the following vulnerability has been
resolved: inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released. This affects skb fragments
reassembled via netfilter or similar modules, e.g. openvswitch or ct_act.c,
when run as part of tx pipeline. Eric Dumazet made an initial analysis of
this bug. Quoting Eric: Calling ip_defrag() in output path is also implying
skb_orphan(), which is buggy because output path relies on sk not
disappearing. A relevant old patch about the issue was : 8282f27449b
