CVE-2026-72067

CVE-2026-72067 affects the Linux kernel CPU hotplug path. The issue arises in cpuhp_invoke_callback() where, if one instance fails, the rollback path reuses the prior return value, which can hide the original error and make a failed transition appear successful. The fix is to keep the rollback re...

CVE-2026-72066

CVE-2026-72066 affects the Linux kernel: cpu: hotplug bound hotplug states sysfs output. The issue arises when states_show() writes CPU hotplug state names into a single sysfs buffer with sprintf(), which can overflow the PAGE_SIZE buffer when many states are registered. The documented fix is to ...

CVE-2026-72065

The CVE-2026-72065 issue affects the Linux kernel networking path for mana devices: it fixes a vulnerability where the packet length reported by the NIC RX CQE could be unchecked before skb processing. The underlying problem is trusting CQE-reported lengths from the NIC and passing them to skb ha...

CVE-2026-72064

CVE-2026-72064 relates to the Linux kernel net: mana RX path. When frag_count > 1, RX buffers are allocated from page pool fragments and remain DMA mapped; the RX completion path omits dma_unmap_single(), so the implicit CPU sync is not performed before passing data to the networking stack. Th...

CVE-2026-72063

CVE-2026-72063 affects Linux kernel Tegra GPIO direction handling. The fix removes redundant pinctrl_gpio_direction_input()/pinctrl_gpio_direction_output() calls, which previously entered the pinctrl core and could sleep in atomic context while a per-line spinlock was held. tegra_gpio_direction_i...

CVE-2026-72062

CVE-2026-72062 affects the Linux kernel GPIO path for mt7621, where bank-wide interrupt-trig state (rising/falling) could be corrupted by non-atomic read-modify-write updates when multiple IRQs on the same bank run concurrently. The issue arises because each gpio chip instance represents a 32-pin...

CVE-2026-72060

The CVE-2026-72060 entry concerns a Linux kernel issue in the TI ICSSG Ethernet driver where icssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name() for FW PA stats even if the PA stats block is absent. The root cause is that emac_get_stat_by_name() relies on pa_stats guard, but the...

CVE-2026-72061

The CVE refers to a Linux kernel vulnerability where net: sit requires CAP_NET_ADMIN in the device netns for changelink. ipip6_changelink() can operate across at most two netnamespaces (dev_net(dev) and the tunnel link netns t->net), which may differ if a device is created or moved to another ...

CVE-2026-72059

Summary: The CVE-2026-72059 issue in the Linux kernel affects the wwan t7xx driver. During CLDMA late initialization, md_ctrl->gpd_dmapool is created before TX/RX rings are initialized. If a ring init fails, the code frees initialized rings but leaks the DMA pool. Consequence: potential DMA po...

CVE-2026-72058

Summary: The CVE-2026-72058 issue in the Linux kernel affects the ixp4xx_hss HDLC netdev allocation. In ixp4xx_hss_probe, two separate HDLC netdevs were allocated: the first was stored in ndev, initialized, and registered, while the second was stored in port->netdev and later used by the remov...

CVE-2026-72056

Summary (CVE-2026-72056): In the Linux kernel, the ENA driver’s XDP TX queue handling leaks resources when regular TX queue setup fails. Specifically, create_queues_with_size_backoff() creates XDP TX queues prior to establishing the regular TX path; if the subsequent allocation/creation of regula...

CVE-2026-72057

In CVE-2026-72057, the Linux kernel net/sched code path act_ct is vulnerable due to tc_skb_cb not being preserved when defragmenting. The function tcf_ct_handle_fragments() calls nf_ct_handle_fragments() without saving/restoring skb->cb, and the defrag helper clears IPCB/IP6CB that alias the t...

CVE-2026-72055

The CVE-2026-72055 entry concerns a Linux kernel net: ip6_vti issue where vti6_changelink could be mishandled across net namespaces. The root cause is that CAP_NET_ADMIN was only checked against dev_net(dev) during the rtnl changelink path, allowing a caller with privileges in the device namespac...

CVE-2026-72054

CVE-2026-72054 concerns the Linux kernel’s net/vti changelink operation. The root cause is that vti_changelink() validated CAP_NET_ADMIN against the device netns (dev_net) but not against the tunnel’s netns (t->net), allowing a caller privileged in dev_net but not in t->net to rewrite a tun...

CVE-2026-72052

The CVE-2026-72052 issue affects the Linux kernel's IP6GRE/IP6ERSPAN changelink logic. Specifically, ip6gre_changelink() and ip6erspan_changelink() could be manipulated if a caller is privileged in dev_net(dev) but not in the tunnel’s netns (t->net). The vulnerability arises because the rtnl c...

CVE-2026-72053

The CVE-2026-72053 entry describes a Linux kernel vulnerability in the ipip driver related to changelink in ipip_changelink(). The issue arises because CAP_NET_ADMIN is checked only against the device’s netns (dev_net(dev)) while a tunnel can reside in a different netns (t->net), allowing a pr...

CVE-2026-72051

The CVE-2026-72051 issue affects the Linux kernel’s ip6_tunnel code: ip6_tnl_changelink() incorrectly checks CAP_NET_ADMIN only against the device netns (dev_net(dev)), allowing a caller privileged in that netns but not in the tunnel’s netns (t->net) to rewrite a tunnel. The remediation is toG...

CVE-2026-72050

The CVE-2026-72050 entry concerns the Linux kernel subsystem octeontx2-af where BPID bitmap handling in setup is flawed. Specifically, nix_setup_bpids() allocates bp->bpids via rvu_alloc_bitmap() (using a plain kcalloc). If any subsequent devm_kcalloc() allocations for the BPID mapping arrays ...

CVE-2026-72048

Linux kernel: ieee802154 ca8210 driver leaks cas_ctl on spi_async failure due to kzalloc_obj(GFP_ATOMIC) allocation that is only freed in the completion callback. On submission failure, spi_async() does not queue a callback, leaving cas_ctl and embedded spi_message/spi_transfer orphaned. The leak...

CVE-2026-72049

The CVE affects the Linux kernel ieee802154 code path: the legacy IEEE802154_NL netlink dump entries (LLSEC_LIST_KEY, LLSEC_LIST_DEV, LLSEC_LIST_DEVKEY, LLSEC_LIST_SECLEVEL) are built with IEEE802154_DUMP(), which sets no .flags, allowing unprivileged NETLINK_GENERIC readers to dump the 16-byte A...
