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...

CVE-2026-72234 batman-adv: access unicast_ttvn skb->data only after skb realloc

In the Linux kernel, the following vulnerability has been resolved: batman-adv: access unicastttvn skb-data only after skb realloc The pskbmaypull called by batadvgetvid could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: free unfragmentable packet The caller of batadvfragsendpacket assume that the skb provided to the function are always consumed. But the pre-check for an empty payload or the zero fragment size returned an error...

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-2026-72021

Summary: The CVE-2026-72021 issue affects the Linux kernel’s IPVS SCTP state lookup. The kernel incorrectly read the SCTP chunk header using a wrong offset for IPv6 when extension headers were present, causing misclassification of handshake steps (e.g., INIT1 vs ESTABLISHED) and incorrect managem...
