In the Linux kernel, the following vulnerability has been
resolved: nfsd: fix use-after-free due to delegation race A delegation
break could arrive as soon as we've called vfs_setlease. A delegation break
runs a callback which immediately (in nfsd4_cb_recall_prepare) adds the
delegation to del_recall_lru. If we then exit nfs4_set_delegation without
hashing the delegation, it will be freed as soon as the callback is done
with it, without ever being removed from del_recall_lru. Symptoms show up
later as use-after-free or list corruption warnings, usually in the
laundromat thread. I suspect aba2072f4523 'nfsd: grant read delegations to

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

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 rele

Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may

the first place, as it's the inverse order of what the submitting thread
will do.(CVE-2024-26585)
