CVE-2026-72351

CVE-2026-72351 : In the Linux kernel, the vulnerability concerns GUE private flags indicating REMCSUM metadata. The root cause is that guehdr_priv_flags_len() returns 0 when GUE_PFLAG_REMCSUM is set, allowing a packet with only the private flags field to pass validate_gue_flags(). Consequently, g...

EUVD-2026-59247

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6tables: mark malformed IPv6 extension headers for hotdrop The ah, hbh and rt matches check that the fixed extension header is present, then use the header length field to derive the advertised extension header lengt...

CVE-2026-72348

The CVE-2026-72348 entry concerns the Linux kernel netfilter ip6tables handling of IPv6 extension headers (ah, hbh, rt). The issue stems from checks that derive the advertised extension header length from header length fields; improper advertised-length checks allowed malformed headers to bypass ...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix malformed ISOEND/CONT handling Core specification Part C vol 4 sec 5.4.5 does not exclude empty ISOCONT, ISOEND packets. We currently reject them if they are last. If controller sends malformed sequence ISOSTA...

CVE-2026-72326 net/sched: cake: reject overhead values that underflow length

In the Linux kernel, the following vulnerability has been resolved: net/sched: cake: reject overhead values that underflow length CAKE accepts signed overhead values and stores them in an s16, but the adjusted packet length calculation uses unsigned arithmetic. A negative effective length can...

CVE-2026-72296

The CVE-2026-72296 entry describes a Linux kernel vulnerability in the net/ife path where ife_decode() could return after pulling only the outer IFE header and metadata, causing eth_type_trans() to see an inner Ethernet header that may be absent in the linear data area. This could lead to a crash...

CVE-2026-72251

CVE-2026-72251 concerns the Linux kernel netfilter nf_nat_sip path. The issue is a memory-pointer/buffer handling flaw: if skb_ensure_writable() reallocates a cloned/fragmented skb, nf_nat_sip() may not update the destination pointer (dptr ) to the new buffer, risking a stale data pointer and pot...

CVE-2026-72234

The CVE relates to the Linux kernel’s batman-adv code. A use-after-free could occur when pskb_may_pull() reallocates the buffer behind skb, and pointers (notably the unicast_packet pointer) are not reassigned, after skb data is accessed. The issue was fixed by ensuring reassignment for affected p...
