| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index\n\nWith numa balancing on, when a numa system is running where a numa node\ndoesn't have its local memory so it has no managed zones, the following\noops has been observed. It's because wakeup_kswapd() is called with a\nwrong zone index, -1. Fixed it by checking the index before calling\nwakeup_kswapd().\n\n> BUG: unable to handle page fault for address: 00000000000033f3\n> #PF: supervisor read access in kernel mode\n> #PF: error_code(0x0000) - not-present page\n> PGD 0 P4D 0\n> Oops: 0000 [#1] PREEMPT SMP NOPTI\n> CPU: 2 PID: 895 Comm: masim Not tainted 6.6.0-dirty #255\n> Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS\n> rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014\n> RIP: 0010:wakeup_kswapd (./linux/mm/vmscan.c:7812)\n> Code: (omitted)\n> RSP: 0000:ffffc90004257d58 EFLAGS: 00010286\n> RAX: ffffffffffffffff RBX: ffff88883fff0480 RCX: 0000000000000003\n> RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff88883fff0480\n> RBP: ffffffffffffffff R08: ff0003ffffffffff R09: ffffffffffffffff\n> R10: ffff888106c95540 R11: 0000000055555554 R12: 0000000000000003\n> R13: 0000000000000000 R14: 0000000000000000 R15: ffff88883fff0940\n> FS: 00007fc4b8124740(0000) GS:ffff888827c00000(0000) knlGS:0000000000000000\n> CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n> CR2: 00000000000033f3 CR3: 000000026cc08004 CR4: 0000000000770ee0\n> DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n> DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n> PKRU: 55555554\n> Call Trace:\n> <TASK>\n> ? __die\n> ? page_fault_oops\n> ? __pte_offset_map_lock\n> ? exc_page_fault\n> ? asm_exc_page_fault\n> ? wakeup_kswapd\n> migrate_misplaced_page\n> __handle_mm_fault\n> handle_mm_fault\n> do_user_addr_fault\n> exc_page_fault\n> asm_exc_page_fault\n> RIP: 0033:0x55b897ba0808\n> Code: (omitted)\n> RSP: 002b:00007ffeefa821a0 EFLAGS: 00010287\n> RAX: 000055b89983acd0 RBX: 00007ffeefa823f8 RCX: 000055b89983acd0\n> RDX: 00007fc2f8122010 RSI: 0000000000020000 RDI: 000055b89983acd0\n> RBP: 00007ffeefa821a0 R08: 0000000000000037 R09: 0000000000000075\n> R10: 0000000000000000 R11: 0000000000000202 R12: 0000000000000000\n> R13: 00007ffeefa82410 R14: 000055b897ba5dd8 R15: 00007fc4b8340000\n> </TASK>" |
