In the Linux kernel, the following vulnerability has been resolved: nfc: nci: fix uninit-value in the RF discover/activated NTF handlers ncirfdiscoverntfpacket and ncirfintfactivatedntfpacket each parse a notification into an on-stack struct ncirfdiscoverntf / ncirfintfactivatedntf that is not...

CVE-2026-80794

This Linux kernel vulnerability affects the NFC NCI subsystem, specifically the nci_rf_discover_ntf_packet() and nci_rf_intf_activated_ntf_packet() handlers. The root cause is that on-stack notification structs are not zero-initialised before parsing. When a notification reports a zero rf_tech_sp...

In the Linux kernel, the following vulnerability has been resolved: ipv4: reject undersized MTUs in ipdofragment ipdofragment subtracts the IPv4 header length from the effective MTU and passes the resulting payload MTU to ipfragnext. If the effective MTU is smaller than hlen + 8, ipfragnext round...

CVE-2026-80793

This Linux kernel vulnerability affects the IPv4 fragmentation path in ip_do_fragment() . When the effective MTU is smaller than the IPv4 header length plus 8, the function passes a zero-length payload to ip_frag_next() , causing the fragmentation state to stall indefinitely. The result is a soft...

CVE-2026-80792

CVE-2026-80792 is a use-after-free vulnerability in the Linux kernel 's IPv6 output path. In ip6_finish_output2(), a pointer to the IPv6 destination address (daddr ) is cached before calling lwtunnel_xmit(). Because the LWT-BPF transmit path or other encapsulation operations can reallocate the sk...
