🚨 CVE-2026-63946
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: fix UAF in iso_recv_frame
iso_recv_frame reads conn->sk under iso_conn_lock but releases the lock
before using sk, with no reference held. A concurrent iso_sock_kill()
can free sk in that...
🚨 CVE-2026-63947
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: HIDP: fix missing length checks in hidp_input_report()
hidp_input_report() reads keyboard and mouse payload data from an skb
without first verifying that skb->len contains enough data...
🚨 CVE-2026-63952
In the Linux kernel, the following vulnerability has been resolved:
memfd: deny writeable mappings when implying SEAL_WRITE
When SEAL_EXEC is added, SEAL_WRITE is implied to make W^X. But the
implied seal is set after the check that makes sure the memfd can not have
any...
🚨 CVE-2026-63968
In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix possible infinite loop in fib6_select_path()
Found while auditing the same pattern Sashiko reported in
rt6_fill_node() [1]. Apply the same fix as
commit f8d8ce1b515a ("ipv6: fix possible infinite...
🚨 CVE-2026-63970
In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: bind uarg before filling zerocopy skb
virtio_transport_send_pkt_info() allocates or reuses the zerocopy uarg
before entering the send loop, but virtio_transport_alloc_skb() still
fills the skb...
🚨 CVE-2026-63971
In the Linux kernel, the following vulnerability has been resolved:
sctp: fix race between sctp_wait_for_connect and peeloff
sctp_wait_for_connect() drops and re-acquires the socket lock while
waiting for the association to reach ESTABLISHED state. During this
window, another...
🚨 CVE-2026-63974
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Set HCI_CMD_DRAIN_WORKQUEUE during device close
Since hci_dev_close_sync() can now be called during the reset path, we
should also set HCI_CMD_DRAIN_WORKQUEUE. This avoids queuing timeouts...
🚨 CVE-2026-63975
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp
If dcid is received for an already-assigned destination CID the spec
requires that both channels to be discarded, but calling l2cap_chan_del
may...
🚨 CVE-2026-63976
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: l2cap: clear chan->ident on ECRED reconfiguration success
l2cap_ecred_reconf_rsp() returns early on success without clearing
chan->ident. Every other L2CAP response handler (l2cap_ecred_conn_rsp...
🚨 CVE-2026-63977
In the Linux kernel, the following vulnerability has been resolved:
dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work
The change_work was introduced to send device change notifications
from DPLL device callbacks without deadlocking on dpll_lock, since
the...
🚨 CVE-2026-63978
In the Linux kernel, the following vulnerability has been resolved:
net/handshake: Drain pending requests at net namespace exit
The arguments to list_splice_init() in handshake_net_exit() are
reversed. The call moves the local empty "requests" list onto
hn->hn_requests...
🚨 CVE-2026-63979
In the Linux kernel, the following vulnerability has been resolved:
net/handshake: hand off the pinned file reference to accept_doit
handshake_req_next() removes the request from the per-net
pending list and drops hn_lock before handshake_nl_accept_doit()
reads...
🚨 CVE-2026-63980
In the Linux kernel, the following vulnerability has been resolved:
net/handshake: Use spin_lock_bh for hn_lock
nvmet_tcp_state_change(), a socket callback that runs in BH context,
can reach handshake_req_cancel() via nvmet_tcp_schedule_release_queue()
and...
🚨 CVE-2026-63984
In the Linux kernel, the following vulnerability has been resolved:
ipv6: rpl: fix hdrlen overflow in ipv6_rpl_srh_decompress()
ipv6_rpl_srh_decompress() computes:
outhdr->hdrlen = (((n + 1) * sizeof(struct in6_addr)) >> 3);
hdrlen is __u8. For n >= 127 the result exceeds...
🚨 CVE-2026-63985
In the Linux kernel, the following vulnerability has been resolved:
ethtool: eeprom: add more safeties to EEPROM Netlink fallback
The Netlink fallback path for reading module EEPROM
(fallback_set_params()) validates that offset < eeprom_len,
but does not check that offset +...
🚨 CVE-2026-63992
In the Linux kernel, the following vulnerability has been resolved:
tunnels: do not assume transport header in iptunnel_pmtud_check_icmp()
In some cases, iptunnel_pmtud_check_icmp() can be called while
skb transport header is not set.
This triggers an out-of-bound access...
🚨 CVE-2026-63993
In the Linux kernel, the following vulnerability has been resolved:
vxlan: do not reuse cached ip_hdr() value after skb_tunnel_check_pmtu()
skb_tunnel_check_pmtu() can change skb->head.
Reusing old_iph afer skb_tunnel_check_pmtu() can cause an UAF.
Use instead ip_hdr(skb) as...
🚨 CVE-2026-63994
In the Linux kernel, the following vulnerability has been resolved:
tunnels: load network headers after skb_cow() in iptunnel_pmtud_build_icmp[v6]()
Sashiko found that iptunnel_pmtud_build_icmp() and
iptunnel_pmtud_build_icmpv6() were caching ip_hdr() and ipv6_hdr()
before an...
🚨 CVE-2026-63995
In the Linux kernel, the following vulnerability has been resolved:
ethtool: cmis: validate start_cmd_payload_size from module
The CMIS firmware update code reads start_cmd_payload_size from
the module's FW Management Features CDB reply and uses it directly
as the byte count...
🚨 CVE-2026-63996
In the Linux kernel, the following vulnerability has been resolved:
ethtool: cmis: require exact CDB reply length
Malicious SFP module could respond with rpl_len longer than
what cmis_cdb_process_reply() expected, leading to OOB writes.
Malicious HW is a bit theoretical but...
