CVE ID :CVE-2026-46320<\/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
tap: free page on error paths in tap_get_user_xdp()<\/p>\n
tap_get_user_xdp() rejects a frame shorter than ETH_HLEN with -EINVAL,
\nand returns -ENOMEM when build_skb() fails. Both paths jump to the err
\nlabel without freeing the page that vhost_net_build_xdp() allocated for
\nthe frame. tap_sendmsg() discards the per-buffer return value and always
\nreturns 0, so vhost_tx_batch() takes the success path and never frees
\nthe page; each rejected frame in a batch leaks one page-frag chunk.<\/p>\n
Free the page on both error paths, before the skb is built. This is the
\ntap counterpart of the same leak in tun_xdp_one().<\/p>\n
Severity: 0.0 | NA<\/p>\n
