| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: E-Switch, pair only capable devices
OFFLOADS paring using devcom is possible only on devices
that support LAG. Filter based on lag capabilities.
This fixes an issue where mlx5_get_next_phys_dev() was
called without holding the interface lock.
This issue was found when commit
bc4c2f2e0179 ("net/mlx5: Lag, filter non compatible devices")
added an assert that verifies the interface lock is held.

| In the Linux kernel, the following vulnerability has been resolved:
ip_gre: test csum_start instead of transport header
GRE with TUNNEL_CSUM will apply local checksum offload on
CHECKSUM_PARTIAL packets.
ipgre_xmit must validate csum_start after an optional skb_pull,
else lco_csum may trigger an overflow. The original check was
if (csum && skb_checksum_start(skb) < skb->data)
return -EINVAL;
This had false positives when skb_checksum_start is undefined:
when ip_summed is not CHECKSUM_PARTIAL. A discussed refinement
was straightforward
if (csum && skb->ip_summed == CHECKSUM_PARTIAL &&
skb_checksum_start(skb) < skb->data)
return -EINVAL;
But was eventually revised more thoroughly:
- restrict the check to the only branch where needed, in an
uncommon GRE path that uses header_ops and calls skb_pull.
- test skb_transport_header, which is set along with csum_start
in skb_partial_csum_set in the normal header_ops datapath.
Turns out skbs can arrive in this branch without the transport
header set, e.g., through BPF redirection.
Revise the check back to check csum_start directly, and only if
CHECKSUM_PARTIAL. Do leave the check in the updated location.
Check field regardless of whether TUNNEL_CSUM is configured. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid cycles in directory h-tree
A maliciously corrupted filesystem can contain cycles in the h-tree
stored inside a directory. That can easily lead to the kernel corrupting
tree nodes that were already verified under its hands while doing a node
split and consequently accessing unallocated memory. Fix the problem by
verifying traversed block numbers are unique. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state
The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that
we are in the middle of replay the fast commit journal. This was
actually a mistake, since the sbi->s_mount_info is initialized from
es->s_state. Arguably s_mount_state is misleadingly named, but the
name is historical --- s_mount_state and s_state dates back to ext2.
What should have been used is the ext4_{set,clear,test}_mount_flag()
inline functions, which sets EXT4_MF_* bits in sbi->s_mount_flags.
The problem with using EXT4_FC_REPLAY is that a maliciously corrupted
superblock could result in EXT4_FC_REPLAY getting set in
s_mount_state. This bypasses some sanity checks, and this can trigger
a BUG() in ext4_es_cache_extent(). As a easy-to-backport-fix, filter
out the EXT4_FC_REPLAY bit for now. We should eventually transition
away from EXT4_FC_REPLAY to something like EXT4_MF_REPLAY. |
| In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Trap RDMA segment overflows
Prevent svc_rdma_build_writes() from walking off the end of a Write
chunk's segment array. Caught with KASAN.
The test that this fix replaces is invalid, and might have been left
over from an earlier prototype of the PCL work. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: tcp_rtx_synack() can be called from process context
Laurent reported the enclosed report [1]
This bug triggers with following coditions:
0) Kernel built with CONFIG_DEBUG_PREEMPT=y
1) A new passive FastOpen TCP socket is created.
This FO socket waits for an ACK coming from client to be a complete
ESTABLISHED one.
2) A socket operation on this socket goes through lock_sock()
release_sock() dance.
3) While the socket is owned by the user in step 2),
a retransmit of the SYN is received and stored in socket backlog.
4) At release_sock() time, the socket backlog is processed while
in process context.
5) A SYNACK packet is cooked in response of the SYN retransmit.
6) -> tcp_rtx_synack() is called in process context.
Before blamed commit, tcp_rtx_synack() was always called from BH handler,
from a timer handler.
Fix this by using TCP_INC_STATS() & NET_INC_STATS()
which do not assume caller is in non preemptible context.

| In the Linux kernel, the following vulnerability has been resolved:
sfc: fix considering that all channels have TX queues
Normally, all channels have RX and TX queues, but this is not true if
modparam efx_separate_tx_channels=1 is used. In that cases, some
channels only have RX queues and others only TX queues (or more
preciselly, they have them allocated, but not initialized).
Fix efx_channel_has_tx_queues to return the correct value for this case
too.
