CVE-2026-23475 spi: fix statistics allocation
In the Linux kernel, the following vulnerability has been resolved: spi: fix statistics allocation The controller per-cpu statistics is not allocated until after the controller has been registered with driver core, which leaves a window where accessing the sysfs attributes can trigger a...
CVE-2026-23459
The CVE-2026-23459 issue affects the Linux kernel IP tunnel code, specifically iptunnel_xmit_stats(). The bug arose because the function assumed tunnels used NETDEV_PCPU_STAT_TSTATS, while vxlan/geneve tunnels call udp_tunnel[6]_xmit_skb() and read NETDEV_PCPU_STAT_DSTATS, creating potential data...
CVE-2026-23459 ip_tunnel: adapt iptunnel_xmit_stats() to NETDEV_PCPU_STAT_DSTATS
In the Linux kernel, the following vulnerability has been resolved: iptunnel: adapt iptunnelxmitstats to NETDEVPCPUSTATDSTATS Blamed commits forgot that vxlan/geneve use udptunnel6xmitskb which call iptunnelxmitstats. iptunnelxmitstats was assuming tunnels were only using NETDEVPCPUSTATTSTATS...

CVE-2026-23374
A flaw was found in the Linux kernel's blktrace component. This vulnerability arises when the tracingrecordcmdline function attempts to access a per-CPU variable in a preemptible context, which is an unsafe operation. A local attacker could exploit this to trigger a kernel bug, potentially leadin...
