Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: qede: ensure that the skb is allocated before use. qedebuildskb assumes that buildskb always works and proceeds directly to skbreserve. However, buildskb may fail under memory pressure. This results in a kernel panic because the...

EUVD-2026-55516

In the Linux kernel, the following vulnerability has been resolved: net: hip04: fix RX buffer leak on buildskb failure When buildskb fails in hip04rxpoll, the driver jumps to the refill path without releasing the current RX buffer and its DMA mapping. Installing a replacement buffer then overwrit...

SUSE CVE-2026-46322

In the Linux kernel, the following vulnerability has been resolved: tun: free page on buildskb failure in tunxdpone When buildskb fails in tunxdpone, the function sets ret to -ENOMEM and jumps to the out label, which returns without freeing the page that vhostnetbuildxdp allocated for the frame. ...

CVE-2026-46322

A flaw was found in the Linux kernel's tun driver. This vulnerability occurs when the buildskb function fails within tunxdpone, leading to a failure to free an allocated memory page. Each such failure results in a memory leak, where a 'page-frag chunk' is not released. Over time, repeated...

UBUNTU-CVE-2026-46322

In the Linux kernel, the following vulnerability has been resolved: tun: free page on buildskb failure in tunxdpone When buildskb fails in tunxdpone, the function sets ret to -ENOMEM and jumps to the out label, which returns without freeing the page that vhostnetbuildxdp allocated for the frame. ...

CVE-2026-46322

The CVE relates to the Linux kernel tun driver vulnerability CVE-2026-46322. When build_skb() fails inside tun_xdp_one(), the function returns -ENOMEM without freeing the allocated page for the frame, causing a memory leak of one page-frag chunk per failed build_skb() in a batch. The root cause i...
