It is a value in\nthe u8 range. The final length we pass to av7110_ipack_instant_repack()\nis \"len - (buf[4] + 1) - 4\" so add a check to ensure that the length is\nnot negative. It's not clear that passing a negative len value does\nanything bad necessarily, but it's not best practice.\n\nWith the new bounds checking the \"if (!len)\" condition is no longer\npossible or required so remove that.(CVE-2023-54284)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nipvs: Defer ip_vs_ftp unregister during netns cleanup\n\nOn the netns cleanup path, __ip_vs_ftp_exit() may unregister ip_vs_ftp\nbefore connections with valid cp->app pointers are flushed, leading to a\nuse-after-free.\n\nFix this by introducing a global `exiting_module` flag, set to true in\nip_vs_ftp_exit() before unregistering the pernet subsystem. In\n__ip_vs_ftp_exit(), skip ip_vs_ftp unregister if called during netns\ncleanup (when exiting_module is false) and defer it to\n__ip_vs_cleanup_batch(), which unregisters all apps after all connections\nare flushed. If called during module exit, unregister ip_vs_ftp\nimmediately.(CVE-2025-40018)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: fix potential use-after-free in have_mon_and_osd_map()\n\nThe wait loop in __ceph_open_session() can race with the client\nreceiving a new monmap or osdmap shortly after the initial map is\nreceived.
