Title
crypto: authencesn - reject too-short AAD (assoclen<8) to match ESP/ESN spec
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: authencesn - reject too-short AAD (assoclen<8) to match ESP/ESN spec
authencesn assumes an ESP/ESN-formatted AAD. When assoclen is shorter than
the minimum expected length, crypto_authenc_esn_decrypt() can advance past
the end of the destination scatterlist and trigger a NULL pointer dereference
in scatterwalk_map_and_copy(), leading to a kernel panic (DoS).
Add a minimum AAD length check to fail fast on invalid inputs.
Severity
No CVSS data available.

Title
crypto: algif_aead - Revert to operating out-of-place
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - Revert to operating out-of-place
This mostly reverts commit 72548b093ee3 except for the copying of
the associated data.
There is no benefit in operating in-place in algif_aead since the
source and destination come from different mappings. Get rid of
all the complexity added for in-place operation and just copy the
AD directly.

Title
crypto: af_alg - limit RX SG extraction by receive buffer budget
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - limit RX SG extraction by receive buffer budget
Make af_alg_get_rsgl() limit each RX scatterlist extraction to the
remaining receive buffer budget.
af_alg_get_rsgl() currently uses af_alg_readable() only as a gate
before extracting data into the RX scatterlist. Limit each extraction
to the remaining af_alg_rcvbuf(sk) budget so that receive-side
accounting matches the amount of data attached to the request.
If skcipher cannot obtain enough RX space for at least one chunk while
more data remains to be processed, reject the recvmsg call instead of
rounding the request length down to zero.
Severity
No CVSS data available.

Title
xfrm: esp: avoid in-place decrypt on shared skb frags
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: esp: avoid in-place decrypt on shared skb frags
MSG_SPLICE_PAGES can attach pages from a pipe directly to an skb. TCP
marks such skbs with SKBFL_SHARED_FRAG after skb_splice_from_iter(),
so later paths that may modify packet data can first make a private
copy. The IPv4/IPv6 datagram append paths did not set this flag when
splicing pages into UDP skbs.
That leaves an ESP-in-UDP packet made from shared pipe pages looking
like an ordinary uncloned nonlinear skb. ESP input then takes the no-COW
fast path for uncloned skbs without a frag_list and decrypts in place
over data that is not owned privately by the skb.
Mark IPv4/IPv6 datagram splice frags with SKBFL_SHARED_FRAG, matching
TCP. Also make ESP input fall back to skb_cow_data() when the flag is
present, so ESP does not decrypt externally backed frags in place.
Private nonlinear skb frags still use the existing fast path.
This intentionally does not change ESP output. In esp_output_head(),
the path that appends the ESP trailer to existing skb tailroom without
calling skb_cow_data() is not reachable for nonlinear skbs:
skb_tailroom() returns zero when skb->data_len is nonzero, while ESP
tailen is positive. Thus ESP output will either use the separate
destination-frag path or fall back to skb_cow_data().

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfrm: esp: avoid in-place decrypt on shared skb frags\n\nMSG_SPLICE_PAGES can attach pages from a pipe directly to an skb. TCP\nmarks such skbs with SKBFL_SHARED_FRAG after skb_splice_from_iter(),\nso later paths that may modify packet data can first make a private\ncopy. The IPv4/IPv6 datagram append paths did not set this flag when\nsplicing pages into UDP skbs.\n\nThat leaves an ESP-in-UDP packet made from shared pipe pages looking\nlike an ordinary uncloned nonlinear skb. ESP input then takes the no-COW\nfast path for uncloned skbs without a frag_list and decrypts in place\nover data that is not owned privately by the skb.\n\nMark IPv4/IPv6 datagram splice frags with SKBFL_SHARED_FRAG, matching\nTCP. Also make ESP input fall back to skb_cow_data() when the flag is\npresent, so ESP does not decrypt externally backed frags in place.\nPrivate nonlinear skb frags still use the existing fast path.\n\nThis intentionally does not change ESP output. In esp_output_head(),\nthe path that appends the ESP trailer to existing skb tailroom without\ncalling skb_cow_data() is not reachable for nonlinear skbs:\nskb_tailroom() returns zero when skb-\u003edata_len is nonzero, while ESP\ntailen is positive. Thus ESP output will either use the separate\ndestination-frag path or fall back to skb_cow_data()."
