In the Linux kernel, the following vulnerability has been resolved:

vsock: Fix transport_* TOCTOU

Transport assignment may race with module unload. Protect new_transport from becoming a stale pointer.

This also takes care of an insecure call in vsock_use_local_transport(); add a lockdep assert.

OESA-2026-2417 — kernel security update

Affected: openEuler:24.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:mm/mempolicy: fix migrate_to_node() assuming there is at least one VMA in a MMWe currently assume that there is at least one VMA in a MM, which isn ttrue.So we might end up having find_vma() return NULL, to then de-referenceNULL. So properly handle find_vma() returning NULL.This fixes the report:Oops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN PTIKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]CPU: 1 UID: 0 PID: 6021 Comm: syz-executor284 Not tainted 6.12.0-rc7-syzkaller-00187-gf868cd251776 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/30/2024RIP: 0010:migrate_to_node mm/mempolicy.c:1090 [inline]RIP: 0010:do_migrate_pages+0x403/0x6f0 mm/mempolicy.c:1194Code: ...RSP: 0018:ffffc9000375fd08 EFLAGS: 00010246RAX: 0000000000000000 RBX: ffffc9000375fd78 RCX: 0000000000000000RDX: ffff88807e171300 RSI: dffffc0000000000 RDI: ffff88803390c044RBP: ffff88807e171428 R08: 0000000000000014 R09: fffffbfff2039ef1R10: ffffffff901cf78f R11: 0000000000000000 R12: 0000000000000003R13: ffffc9000375fe90 R14: ffffc9000375fe98 R15: ffffc9000375fdf8FS: 00005555919e1380(0000) GS:ffff8880b8700000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00005555919e1ca8 CR3: 000000007f12a000 CR4: 00000000003526f0DR0…
