Subject: [PATCH 1/6] bluetooth: Perform careful capability checks in
|
||||
hci_sock_ioctl()
|
||||
|
||||
Previously, capability was checked using capable(), which verified that the
|
||||
caller of the ioctl system call had the required capability. In addition,
|
||||
the result of the check would be stored in the HCI_SOCK_TRUSTED flag,
|
||||
making it persistent for the socket.
|
||||
|
||||
However, malicious programs can abuse this approach by deliberately sharing
|
||||
an HCI socket with a privileged task. The HCI socket will be marked as
|
||||
trusted when the privileged task occasionally makes an ioctl call.
|
||||
|
||||
This problem can be solved by using sk_capable() to check capability, which
|
||||
ensures that not only the current task but also the socket opener has the
|
||||
specified capability, thus reducing the risk of privilege escalation
|
||||
through the previously identified vulnerability.

Subject: [PATCH 2/6] ipvlan:Fix out-of-bounds caused by unclear skb->cb
|
||||
|
||||
If skb enqueue the qdisc, fq_skb_cb(skb)->time_to_send is changed which
|
||||
is actually skb->cb, and IPCB(skb_in)->opt will be used in
|
||||
__ip_options_echo. It is possible that memcpy is out of bounds and lead
|
||||
to stack overflow.
|
||||
We should clear skb->cb before ip_local_out or ip6_local_out.
|
||||
|
||||
v2:
|
||||
1. clean the stack info
|
||||
2. use IPCB/IP6CB instead of skb->cb
|
||||
|
||||
crash on stable-5.10(reproduce in kasan kernel).

In the event of a failure in tcf_change_indev(), fw_set_parms() will

immediately return an error after incrementing or decrementing

reference counter to zero and make reference freed, leading to

In order to prevent this, move the point of possible failure above the

point where the TC_FW_CLASSID is handled.

Subject: [PATCH 4/6] netfilter: nft_set_pipapo: fix improper element removal
|
||||
|
||||
end key should be equal to start unless NFT_SET_EXT_KEY_END is present.
|
||||
|
||||
Its possible to add elements that only have a start key
|
||||
("{ 1.0.0.0 . 2.0.0.0 }") without an internval end.
|
||||
|
||||
Insertion treats this via:
|
||||
|
||||
if (nft_set_ext_exists(ext, NFT_SET_EXT_KEY_END))
|
||||
end = (const u8 *)nft_set_ext_key_end(ext)->data;
|
||||
else
|
||||
end = start;
|
||||
|
||||
but removal side always uses nft_set_ext_key_end().
|
||||
This is wrong and leads to garbage remaining in the set after removal
|
||||
next lookup/insert attempt will give:

Subject: [PATCH 5/6] netfilter: nf_tables: prevent OOB access in
|
||||
nft_byteorder_eval
|
||||
|
||||
When evaluating byteorder expressions with size 2, a union with 32-bit and
|
||||
16-bit members is used. Since the 16-bit members are aligned to 32-bit,
|
||||
the array accesses will be out-of-bounds.
|
||||
|
||||
It may lead to a stack-out-of-bounds access like the one below:

Subject: [PATCH 6/6] net/sched: flower: fix possible OOB write in
|
||||
fl_set_geneve_opt()
|
||||
|
||||
If we send two TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets and their total
|
||||
size is 252 bytes(key->enc_opts.len = 252) then
|
||||
key->enc_opts.len = opt->length = data_len / 4 = 0 when the third
|
||||
TCA_FLOWER_KEY_ENC_OPTS_GENEVE packet enters fl_set_geneve_opt. This
|
||||
bypasses the next bounds check and results in an out-of-bounds.
|
||||
|
||||
Fixes: 0a6e77784f49 ("net/sched: allow flower to match tunnel options")
