PT-2026-90279

Name of the Vulnerable Software and Affected Versions Linux Kernel affected versions not specified Description An issue exists in the ip6 tnl xmit function where the use of skb realloc headroom to expand headroom for outer IPv6 and optional encap headers can lead to a use-after-free scenario. The...

CVE-2026-80825 wifi: mt76: mt7925: ensure tx headroom in usb_sdio_tx_prepare_skb

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: ensure tx headroom in usbsdiotxprepareskb mt7925usbsdiotxprepareskb pushes a TX descriptor and a USB header onto every skb and assumes the headroom for them is already there. That holds for locally generated...

CVE-2026-74743

A flaw was found in the Linux kernel's macvlan component. The macvlan component incorrectly initializes network packet buffer skb headroom and tailroom values, failing to inherit them from the underlying network device. This can occur when the underlying device requires additional space for heade...
