CVE-2026-23320

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: align netdevice lifecycle with bind/unbind Currently, the netdevice is allocated in ncmallocinst and freed in ncmfreeinst. This ties the network interface's lifetime to the configuration instance rather than th...

CVE-2026-23320

CVE-2026-23320 concerns the Linux kernel USB gadget f_ncm driver. The root cause is that the net_device was allocated in ncm_alloc_inst() and freed in ncm_free_inst(), tying the interface lifetime to the configuration instance rather than the USB connection, which can cause the network interface ...

CVE-2026-23309

In the Linux kernel, the following vulnerability has been resolved: tracing: Add NULL pointer check to triggerdatafree If triggerdataalloc fails and returns NULL, eventhisttriggerparse jumps to the outfree error path. While kfree safely handles a NULL pointer, triggerdatafree does not. This cause...

CVE-2026-23309 tracing: Add NULL pointer check to trigger_data_free()

While kfree safely handles a NULL pointer, triggerdatafree does not. This cause...

CVE-2026-23309

CVE-2026-23309 refers to a Linux kernel vulnerability in the tracing subsystem. The issue was a NULL pointer dereference in trigger_data_free() when data->cmd_ops->set_filter is evaluated after a failed trigger_data_alloc() and returning NULL. The root cause was that trigger_data_free() did...

CVE-2026-23304 ipv6: fix NULL pointer deref in ip6_rt_get_dev_rcu()

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix NULL pointer deref in ip6rtgetdevrcu l3mdevmasterdevrcu can return NULL when the slave device is being un-slaved from a VRF. All other callers deal with this, but we lost the fallback to loopback in ip6rtpcpualloc -...

CVE-2026-23304

The connected advisories confirm CVE-2026-23304 affects the Linux kernel IPv6 routing code. Root cause: l3mdev_master_dev_rcu() can return NULL when a slave device is un-slaved from a VRF, and ip6_rt_get_dev_rcu() used by ip6_rt_pcpu_alloc() did not fall back to loopback, causing a NULL pointer d...

CVE-2026-23293 net: vxlan: fix nd_tbl NULL dereference when IPv6 is disabled

In the Linux kernel, the following vulnerability has been resolved: net: vxlan: fix ndtbl NULL dereference when IPv6 is disabled When booting with the 'ipv6.disable=1' parameter, the ndtbl is never initialized because inet6init exits before ndiscinit is called which initializes it. If an IPv6...

CVE-2026-23293

CVE-2026-23293 affects the Linux kernel net/vxlan code. Root cause: when IPv6 is disabled (ipv6.disable=1), nd_tbl is not initialized, leading to a NULL pointer dereference in neigh_lookup() invoked by route_shortcircuit() when an IPv6 packet is injected. Impact is local: a crafted, locally deliv...
