CVE-2026-72463

CVE-2026-72463 (Linux kernel xfrm): The flaw lets a use-after-free occur in xfrm async resumption when xfrm_rcv_cb changes skb->dev to a tunnel device without taking a reference, risking tunnel dev UAF and orig device refcount leaks. The patch stashs the original skb->dev and extends RCU pr...

CVE-2026-72444

CVE-2026-72444 relates to the Linux kernel flow_dissector which could read 12 bytes from eth_hdr(skb) when FLOW_DISSECTOR_KEY_ETH_ADDRS is requested, potentially operating on non-Ethernet or pathologic mac_header states (e.g., TUN in L3 mode). The fix gates the copy to only Ethernet devices (dev-...

CVE-2026-72432

Summary: CVE-2026-72432 affects the Linux kernel, specifically the tpm_crb driver. The issue arises when a device could be matched to a platform driver even if its ACPI companion is absent, due to device_match_driver_override(). Root cause: The probe path did not validate ACPI_COMPANION() for NUL...
