CVE ID :CVE-2026-46322<\/p>\n
Published : June 9, 2026, 12:11 p.m. | 24\u00a0minutes ago<\/p>\n
Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
tun: free page on build_skb failure in tun_xdp_one()<\/p>\n
When build_skb() fails in tun_xdp_one(), the function sets ret to
\n-ENOMEM and jumps to the out label, which returns without freeing the
\npage that vhost_net_build_xdp() allocated for the frame. As with the
\nshort-frame rejection path, tun_sendmsg() discards the per-buffer error
\nand still returns total_len, so vhost_tx_batch() takes the success path
\nand never frees the page. Each build_skb() failure in a batch leaks one
\npage-frag chunk.<\/p>\n
Free the page before taking the error path, matching the put_page() the
\nother error exits of tun_xdp_one() already perform.<\/p>\n
Severity: 0.0 | NA<\/p>\n
