CVE-2024-26640

A vulnerability was found in Linux Kernel where rx zerocopy feature allowed mapping of pages owned by the filesystem, leading to potential system panic which is caused by the lack of sanity checks to rx zerocopy. A local authenticated attacker could exploit this vulnerability to cause a denial of...

CVE-2024-26640

In the Linux kernel, the following vulnerability has been resolved: tcp: add sanity checks to rx zerocopy TCP rx zerocopy intent is to map pages initially allocated from NIC drivers, not pages owned by a fs. This patch adds to canmapfrag these additional checks: - Page must not be a compound one....

CVE-2024-26640

CVE-2024-26640 — Linux kernel TCP rx zerocopy sanity checks (Mode C) Affects: Linux kernel TCP rx zerocopy path. Root cause: can_map_frag() lacked validation when mapping NIC-allocated pages, risking misuse of pages owned by filesystems. The patch adds two checks: (1) the page must not be a compo...
