set: if (trace->type.bit6) { ...
In the Linux kernel, the following vulnerability has been
resolved: xfrm: Wait for RCU readers during policy netns exit
xfrm_policy_fini() frees the policy_bydst hash tables after flushing the
policy work items and deleting all policies, but it does not wait for
concurrent RCU readers to leave their read-side critical sections first.
The policy_bydst tables are published via rcu_assign_pointer() and are
looked up through rcu_dereference_check(), so netns teardown must also wait
for an RCU grace period before freeing the table memory.

In the Linux kernel, the following vulnerability has been
resolved: net/rds: handle zerocopy send cleanup before the message is
queued A zerocopy send can fail after user pages have been pinned but
before the message is attached to the sending socket.
It was discovered that a logic flaw existed in the XFRM ESP-in-TCP
subsystem in the Linux kernel when handling socket buffer fragments. This
flaw is known as Fragnesia. A local attacker could use this to escalate
privileges, or possibly escape a container.)(CVE-2026-43503)
In the Linux kernel, the following vulnerability has been

return an error directly, which will result in stale extent entries
remaining in the extent status tree.
In the Linux kernel, the following vulnerability has been
resolved: smb/client: fix out-of-bounds read in symlink_data() Since
smb2_check_message() returns success without length validation for the
symlink error response, in symlink_data() it is possible for iov->iov_len
to be smaller than sizeof(struct smb2_err_rsp).
In the Linux kernel, the following vulnerability has been
resolved: smb: client: validate dacloffset before building DACL pointers
parse_sec_desc(), build_sec_desc(), and the chown path in
id_mode_to_cifs_acl() all add the server-supplied dacloffset to pntsd
before proving a DACL header fits inside the returned security descriptor.
On 32-bit builds a malicious server can return dacloffset near U32_MAX,
wrap the derived DACL pointer below end_of_acl, and then slip past the
later pointer-based bounds checks.
In the Linux kernel, the following vulnerability has been
resolved: procfs: fix missing RCU protection when reading real_parent in
do_task_stat() When reading /proc/.
It was discovered that a logic flaw existed in the XFRM ESP-in-TCP

When decoding osd_state and osd_weight from an incoming osdmap in
osdmap_decode(), both are decoded for each osd, i.e., map->max_osd times.
The ceph_decode_need() check only accounts for sizeof(*map->osd_weight)
once.
In the Linux kernel, the following vulnerability has been
resolved: nvmet-tcp: propagate nvmet_tcp_build_pdu_iovec() errors to its
callers Currently, when nvmet_tcp_build_pdu_iovec() detects an out-of-
bounds PDU length or offset, it triggers nvmet_tcp_fatal_error(cmd->queue)
and returns early.
In the Linux kernel, the following vulnerability has been
resolved: tipc: fix double-free in tipc_buf_append() tipc_msg_validate()
can potentially reallocate the skb it is validating, freeing the old one.
In tipc_buf_append(), it was being called with a pointer to a local
variable which was a copy of the caller's skb pointer.
In the Linux kernel, the following vulnerability has been
resolved: netfilter: conntrack: remove sprintf usage Replace it with
scnprintf, the buffer sizes are expected to be large enough to hold the
result, no need for snprintf+overflow check.
In the Linux kernel, the following vulnerability has been
resolved: ipv6: fix possible UAF in icmpv6_rcv() Caching saddr and daddr
before pskb_pull() is problematic since skb->head can change.
In the Linux kernel, the following vulnerability has been
resolved: rxrpc: Fix the ACK parser to extract the SACK table for parsing
Fix modification of the received skbuff in rxrpc_input_soft_acks() and a
potential incorrect access of the buffer in a fragmented UDP packet (the
packet would probably have to be deliberately pre-generated as fragmented)
when AF_RXRPC tries to extract the contents of the SACK table by copying
out the contents of the SACK table into a buffer before attempting to parse
AF_RXRPC assumes that it can just call skb_condense() and then validly
access the SACK table from skb->data and that it will be a flat buffer -
but skb_condense() can silently fail to do anything under some
circumstances.
In the Linux kernel, the following vulnerability has been
resolved: IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN In
drivers/infiniband/ulp/isert/ib_isert.c, isert_login_recv_done() computes
the login request payload length as wc->byte_len minus ISER_HEADERS_LEN
with no lower bound, and login_req_len is a signed int.
In the Linux kernel, the following vulnerability has been
resolved: RDMA/srp: bound SRP_RSP sense copy by the received length
srp_process_rsp() copies sense data from rsp->data + resp_data_len, where
resp_data_len is the full 32-bit value supplied by the SRP target and is
never checked against the number of bytes actually received (wc->byte_len).
The copy length is bounded to SCSI_SENSE_BUFFERSIZE, so at most 96 bytes
are copied, but the source offset is not bounded.
In the Linux kernel, the following vulnerability has been
resolved: netfilter: nft_tunnel: fix use-after-free on object destroy
nft_tunnel_obj_destroy() calls metadata_dst_free() which directly kfree()s
the metadata_dst, ignoring the dst_entry refcount.
In the Linux kernel, the following vulnerability has been
resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error
path returns the current descriptor buffer to the hardware BM pool.
In the Linux kernel, the following vulnerability has been

device or checking only that the `ETH_HLEN` bytes at
`skb_mac_header(skb)` lie between `skb->head` and `skb->data`.
Make these paths first verify that the skb is associated with an
Ethernet device, that the MAC header was set, and that it spans at
