Title
netfilter: xt_IDLETIMER: reject rev0 reuse of ALARM timer labels
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: xt_IDLETIMER: reject rev0 reuse of ALARM timer labels
IDLETIMER revision 0 rules reuse existing timers by label and always call
mod_timer() on timer->timer.
If the label was created first by revision 1 with XT_IDLETIMER_ALARM,
the object uses alarm timer semantics and timer->timer is never initialized.
Reusing that object from revision 0 causes mod_timer() on an uninitialized
timer_list, triggering debugobjects warnings and possible panic when
panic_on_warn=1.
Fix this by rejecting revision 0 rule insertion when an existing timer with
the same label is of ALARM type.

"value": "AV:L - This is accessed through the iptables/netfilter sockopt interface (IPT_SO_SET_REPLACE), which requires local system access to create iptables rules. This is a local attack vector via setsockopt syscall.\nAC:L - The attacker can reliably trigger this by first creating a rev1 IDLETIMER rule with XT_IDLETIMER_ALARM flag and a chosen label, then creating a rev0 rule with the same label. No race condition or special conditions needed \u2014 this is a deterministic two-step operation.\nPR:L - The iptables interface requires CAP_NET_ADMIN, but ip_tables.c uses ns_capable(sock_net(sk)-\u003euser_ns, CAP_NET_ADMIN), meaning an unprivileged user can obtain this capability via user namespaces (unshare -Urn), making this reachable from a low-privilege user.\nUI:N - No user interaction is required. The attacker creates both iptables rules themselves without any victim action.\nS:U - The vulnerability stays within the kernel\u0027s security scope \u2014 there is no crossing of a security boundary like VM escape or sandbox escape. It\u0027s a standard kernel privilege escalation scenario.\nC:H - The bug calls mod_timer() on an uninitialized timer_list from kmalloc\u0027d memory. Since kmalloc does not zero memory, the timer_list contains stale heap content which an attacker can influence via heap spraying, potentially achieving arbitrary read through controlled function pointers and timer wheel manipulation.\nI:H - Operating mod_timer() on a timer_list with attacker-influenced stale heap data (uninitialized function pointer, hlist_node entries) can corrupt timer wheel data structures and potentially achieve arbitrary code execution if the function pointer is controlled through heap spraying.\nA:H - At minimum, mod_timer() on uninitialized memory triggers debug_assert_init() WARN which causes panic with panic_on_warn=1. Even without that, following garbage pointers in timer_list-\u003eentry corrupts kernel data structures causing a crash/oops."

Title
netfilter: nf_tables: always walk all pending catchall elements
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: always walk all pending catchall elements
During transaction processing we might have more than one catchall element:
1 live catchall element and 1 pending element that is coming as part of the
new batch.
If the map holding the catchall elements is also going away, its
required to toggle all catchall elements and not just the first viable
candidate.
Otherwise, we get:
WARNING: ./include/net/netfilter/nf_tables.h:1281 at nft_data_release+0xb7/0xe0 [nf_tables], CPU#2: nft/1404

Title
net: vxlan: fix nd_tbl NULL dereference when IPv6 is disabled
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: vxlan: fix nd_tbl NULL dereference when IPv6 is disabled
When booting with the 'ipv6.disable=1' parameter, the nd_tbl is never
initialized because inet6_init() exits before ndisc_init() is called
which initializes it. If an IPv6 packet is injected into the interface,
route_shortcircuit() is called and a NULL pointer dereference happens on

Fix this by adding an early check on route_shortcircuit() when protocol
is ETH_P_IPV6. Note that ipv6_mod_enabled() cannot be used here because
VXLAN can be built-in even when IPv6 is built as a module.

Title
drm/vmwgfx: Return the correct value in vmw_translate_ptr functions
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Return the correct value in vmw_translate_ptr functions
Before the referenced fixes these functions used a lookup function that
returned a pointer. This was changed to another lookup function that
returned an error code with the pointer becoming an out parameter.
The error path when the lookup failed was not changed to reflect this
change and the code continued to return the PTR_ERR of the now
uninitialized pointer. This could cause the vmw_translate_ptr functions
to return success when they actually failed causing further uninitialized
and OOB accesses.

Title
net: bridge: fix nd_tbl NULL dereference when IPv6 is disabled
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: fix nd_tbl NULL dereference when IPv6 is disabled
When booting with the 'ipv6.disable=1' parameter, the nd_tbl is never
initialized because inet6_init() exits before ndisc_init() is called
which initializes it. Then, if neigh_suppress is enabled and an ICMPv6
Neighbor Discovery packet reaches the bridge, br_do_suppress_nd() will
dereference ipv6_stub->nd_tbl which is NULL, passing it to
neigh_lookup(). This causes a kernel NULL pointer dereference.
BUG: kernel NULL pointer dereference, address: 0000000000000268
Oops: 0000 [#1] PREEMPT SMP NOPTI
[...]
RIP: 0010:neigh_lookup+0x16/0xe0

Fix this by replacing IS_ENABLED(IPV6) call with ipv6_mod_enabled() in
the callers. This is in essence disabling NS/NA suppression when IPv6 is
disabled.

Title
icmp: fix NULL pointer dereference in icmp_tag_validation()
Summary
In the Linux kernel, the following vulnerability has been resolved:
icmp: fix NULL pointer dereference in icmp_tag_validation()
icmp_tag_validation() unconditionally dereferences the result of
rcu_dereference(inet_protos[proto]) without checking for NULL.
The inet_protos[] array is sparse -- only about 15 of 256 protocol
numbers have registered handlers. When ip_no_pmtu_disc is set to 3
(hardened PMTU mode) and the kernel receives an ICMP Fragmentation
Needed error with a quoted inner IP header containing an unregistered
protocol number, the NULL dereference causes a kernel panic in
softirq context.
Oops: general protection fault, probably for non-canonical address 0xdffffc0000000002: 0000 [#1] SMP KASAN NOPTI
KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]
RIP: 0010:icmp_unreach (net/ipv4/icmp.c:1085 net/ipv4/icmp.c:1143)
Call Trace:
<IRQ>
icmp_rcv (net/ipv4/icmp.c:1527)
ip_protocol_deliver_rcu (net/ipv4/ip_input.c:207)
ip_local_deliver_finish (net/ipv4/ip_input.c:242)

process_backlog (net/core/dev.c:6628)
handle_softirqs (kernel/softirq.c:561)
</IRQ>
Add a NULL check before accessing icmp_strict_tag_validation. If the
protocol has no registered handler, return false since it cannot
perform strict tag validation.
Severity
No CVSS data available.

Title
clsact: Fix use-after-free in init/destroy rollback asymmetry
Summary
In the Linux kernel, the following vulnerability has been resolved:
clsact: Fix use-after-free in init/destroy rollback asymmetry
Fix a use-after-free in the clsact qdisc upon init/destroy rollback asymmetry.
The latter is achieved by first fully initializing a clsact instance, and
then in a second step having a replacement failure for the new clsact qdisc
instance. clsact_init() initializes ingress first and then takes care of the
egress part. This can fail midway, for example, via tcf_block_get_ext(). Upon
failure, the kernel will trigger the clsact_destroy() callback.
Commit 1cb6f0bae504 ("bpf: Fix too early release of tcx_entry") details the
way how the transition is happening. If tcf_block_get_ext on the q->ingress_block
ends up failing, we took the tcx_miniq_inc reference count on the ingress
side, but not yet on the egress side. clsact_destroy() tests whether the
{ingress,egress}_entry was non-NULL. However, even in midway failure on the
replacement, both are in fact non-NULL with a valid egress_entry from the
previous clsact instance.
What we really need to test for is whether the qdisc instance-specific ingress
or egress side previously got initialized. This adds a small helper for checking
the miniq initialization called mini_qdisc_pair_inited, and utilizes that upon
clsact_destroy() in order to fix the use-after-free scenario. Convert the
ingress_destroy() side as well so both are consistent to each other.

Title
xen/privcmd: restrict usage in unprivileged domU
Summary
In the Linux kernel, the following vulnerability has been resolved:
xen/privcmd: restrict usage in unprivileged domU
The Xen privcmd driver allows to issue arbitrary hypercalls from
user space processes. This is normally no problem, as access is
usually limited to root and the hypervisor will deny any hypercalls
affecting other domains.
In case the guest is booted using secure boot, however, the privcmd
driver would be enabling a root user process to modify e.g. kernel
memory contents, thus breaking the secure boot feature.
The only known case where an unprivileged domU is really needing to
use the privcmd driver is the case when it is acting as the device
model for another guest. In this case all hypercalls issued via the
privcmd driver will target that other guest.
Fortunately the privcmd driver can already be locked down to allow
only hypercalls targeting a specific domain, but this mode can be
activated from user land only today.
The target domain can be obtained from Xenstore, so when not running
in dom0 restrict the privcmd driver to that target domain from the
beginning, resolving the potential problem of breaking secure boot.
This is XSA-482

- defer reading from Xenstore if Xenstore isn't ready yet (Jan Beulich)
- wait in open() if target domain isn't known yet
- issue message in case no target domain found (Jan Beulich)

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxen/privcmd: restrict usage in unprivileged domU\n\nThe Xen privcmd driver allows to issue arbitrary hypercalls from\nuser space processes. This is normally no problem, as access is\nusually limited to root and the hypervisor will deny any hypercalls\naffecting other domains.\n\nIn case the guest is booted using secure boot, however, the privcmd\ndriver would be enabling a root user process to modify e.g. kernel\nmemory contents, thus breaking the secure boot feature.\n\nThe only known case where an unprivileged domU is really needing to\nuse the privcmd driver is the case when it is acting as the device\nmodel for another guest. In this case all hypercalls issued via the\nprivcmd driver will target that other guest.\n\nFortunately the privcmd driver can already be locked down to allow\nonly hypercalls targeting a specific domain, but this mode can be\nactivated from user land only today.\n\nThe target domain can be obtained from Xenstore, so when not running\nin dom0 restrict the privcmd driver to that target domain from the\nbeginning, resolving the potential problem of breaking secure boot.\n\nThis is XSA-482\n\n---\nV2:\n- defer reading from Xenstore if Xenstore isn\u0027t ready yet (Jan Beulich)\n- wait in open() if target domain isn\u0027t known yet\n- issue message in case no target domain found (Jan Beulich)"

No special conditions or race timing required.\nPR:H - The /dev/xen/privcmd device is typically restricted to root access. The attacker needs root privileges within the Xen guest VM, and this cannot be obtained through user namespaces since it requires real access to the Xen device node.\nUI:N - No user interaction is required. The root attacker in the guest VM can directly open the device and issue hypercalls without any victim action.\nS:C - This vulnerability allows bypassing Secure Boot/Lockdown protections. A root user who should be constrained by Secure Boot from modifying kernel memory can use privcmd hypercalls to cross that security boundary and modify kernel memory, defeating the Lockdown security model.\nC:H - Arbitrary hypercalls can be used to read kernel memory contents in the guest, providing full confidentiality compromise of kernel data that Secure Boot/Lockdown is designed to protect.\nI:H - The commit explicitly states the vulnerability allows \"a root user process to modify e.g. kernel memory contents.\" Arbitrary hypercalls enable writing to kernel memory, providing full integrity compromise.\nA:H - With the ability to issue arbitrary hypercalls and modify kernel memory, the attacker can crash the guest kernel or cause denial of service trivially."
