In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
xfrm: esp: restore combined single-frag length gate<\/p>\n
The ESP out-of-place fast path appends the trailer in esp_output_head()
\nbefore esp_output_tail() allocates the destination page frag. The
\nhead-side gate currently checks skb->data_len and tailen separately, but
\nthe tail code allocates a single destination frag from the combined
\npost-trailer skb->data_len.<\/p>\n
Reject the page-frag fast path when the combined aligned length exceeds a
\npage. Otherwise skb_page_frag_refill() may fall back to a single page while
\nthe destination sg still spans the combined skb->data_len.<\/p>\n
Restore this combined-length page gate for both IPv4 and IPv6.<\/p>\n","protected":false},"excerpt":{"rendered":"
