In the Linux kernel, the following vulnerability has been resolved: bonding: fix use-after-free due to enslave fail after slave array update Fix a use-after-free which happens due to enslave failure after the new slave has been added to the array. Since the new slave can be used for Tx immediately, we can use it after it has been freed by the enslave error cleanup path which frees the allocated slave memory. Slave update array is supposed to be called last when further enslave failures are not expected. Move it after xdp setup to avoid any problems. It is very easy to reproduce the problem with a simple xdp_pass prog: ip l add bond1 type bond mode balance-xor ip l set bond1 up ip l set dev bond1 xdp object xdp_pass.o sec xdp_pass ip l add dumdum type dummy Then run in parallel: while :; do ip l set dumdum master bond1 1>/dev/null 2>&1; done; mausezahn bond1 -a own -b rand -A rand -B 1.1.1.1 -c 0 -t tcp "dp=1-1023, flags=syn" The crash happens almost immediately: [ 605.602850] Oops: general protection fault, probably for non-canonical address 0xe0e6fc2460000137: 0000 [#1] SMP KASAN NOPTI [ 605.602916] KASAN: maybe wild-memory-access in range [0x07380123000009b8-0x07380123000009bf] [ 605.602946] CPU: 0 UID: 0 PID: 2445 Comm: mausezahn Kdump: loaded Tainted: G B 6.19.0-rc6+ #21 PREEMPT(voluntary) [ 605.602979] Tainted: [B]=BAD_PAGE [ 605.602998] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 [ 605.603032] RIP: 0010:netdev_core_pick_tx+0xcd/0x210 [ 605.603063] Code: 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 3e 01 00 00 48 b8 00 00 00 00 00 fc ff df 4c 8b 6b 08 49 8d 7d 30 48 89 fa 48 c1 ea 03 <80> 3c 02 00 0f 85 25 01 00 00 49 8b 45 30 4c 89 e2 48 89 ee 48 89 [ 605.603111] RSP: 0018:ffff88817b9af348 EFLAGS: 00010213 [ 605.603145] RAX: dffffc0000000000 RBX: ffff88817d28b420 RCX: 0000000000000000 [ 605.603172] RDX: 00e7002460000137 RSI: 0000000000000008 RDI: 07380123000009be [ 605.603199] RBP: ffff88817b541a00 R08: 0000000000000001 R09: fffffbfff3ed8c0c [ 605.603226] R10: ffffffff9f6c6067 R11: 0000000000000001 R12: 0000000000000000 [ 605.603253] R13: 073801230000098e R14: ffff88817d28b448 R15: ffff88817b541a84 [ 605.603286] FS: 00007f6570ef67c0(0000) GS:ffff888221dfa000(0000) knlGS:0000000000000000 [ 605.603319] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 605.603343] CR2: 00007f65712fae40 CR3: 000000011371b000 CR4: 0000000000350ef0 [ 605.603373] Call Trace: [ 605.603392] <TASK> [ 605.603410] __dev_queue_xmit+0x448/0x32a0 [ 605.603434] ? __pfx_vprintk_emit+0x10/0x10 [ 605.603461] ? __pfx_vprintk_emit+0x10/0x10 [ 605.603484] ? __pfx___dev_queue_xmit+0x10/0x10 [ 605.603507] ? bond_start_xmit+0xbfb/0xc20 [bonding] [ 605.603546] ? _printk+0xcb/0x100 [ 605.603566] ? __pfx__printk+0x10/0x10 [ 605.603589] ? bond_start_xmit+0xbfb/0xc20 [bonding] [ 605.603627] ? add_taint+0x5e/0x70 [ 605.603648] ? add_taint+0x2a/0x70 [ 605.603670] ? end_report.cold+0x51/0x75 [ 605.603693] ? bond_start_xmit+0xbfb/0xc20 [bonding] [ 605.603731] bond_start_xmit+0x623/0xc20 [bonding]

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-688.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix use-after-     free in nf_tables_addchain() nf_tables_addchain() publishes the chain to table->chains via     list_add_tail_rcu() (in nft_chain_add()) before registering hooks. If nf_tables_register_hook() then     fails, the error path calls nft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy() with no     RCU grace period in between. This creates two use-after-free conditions: 1) Control-plane:
    nf_tables_dump_chains() traverses table->chains under rcu_read_lock(). A concurrent dump can still be     walking the chain when the error path frees it. 2) Packet path: for NFPROTO_INET, nf_register_net_hook()     briefly installs the IPv4 hook before IPv6 registration fails. Packets entering nft_do_chain() via the     transient IPv4 hook can still be dereferencing chain->blob_gen_X when the error path frees the chain. Add     synchronize_rcu() between nft_chain_del() and the chain destroy so that all RCU readers -- both dump     threads and in-flight packet evaluation -- have finished before the chain is freed.

Otherwise they will be lost. In this case an AUTOFS_IOC_EXPIRE_MULTI ioctl is done, then a     new waitqueue struct is allocated in autofs_wait(), its initial wait_ctr equals 2. After that     wait_event_killable() is interrupted (it returns -ERESTARTSYS), so that 'wq->name.name == NULL' condition     may be not satisfied. Actually, this condition can be satisfied when autofs_wait_release() or     autofs_catatonic_mode() is called and, what is also important, wait_ctr is decremented in those places.
    Upon the exit of autofs_wait(), wait_ctr is decremented to 1. Then the unmounting process begins: kill_sb     calls autofs_catatonic_mode(), which should have freed the waitqueues, but it only decrements its usage     counter to zero which is not a correct behaviour. edit:imk This description is of course not correct. The     umount performed as a result of an expire is a umount of a mount that has been automounted, it's not the     autofs mount itself. They happen independently, usually after everything mounted within the autofs file     system has been expired away. If everything hasn't been expired away the automount daemon can still exit     leaving mounts in place. But expires done in both cases will result in a notification that calls     autofs_wait_release() with a result status. The problem case is the summary execution of of the automount     daemon. In this case any waiting processes won't be woken up until either they are terminated or the mount     is umounted. end edit: imk So in catatonic mode we should free waitqueues which counter becomes zero.
    edit: imk Initially I was concerned that the calling of autofs_wait_release() and autofs_catatonic_mode()     was not mutually exclusive but that can't be the case (obviously) because the queue entry (or entries) is     removed from the list when either of these two functions are called. Consequently the wait entry will be     freed by only one of these functions or by the woken process in autofs_wait() depending on the order of     the calls. end edit: imk (CVE-2023-54134)

  - In the Linux kernel, the following vulnerability has been resolved: mm: hugetlb: independent PMD page     table shared count The folio refcount may be increased unexpectly through try_get_folio() by caller such     as split_huge_pages. In huge_pmd_unshare(), we use refcount to check whether a pmd page table is shared.
    The check is incorrect if the refcount is increased by the above caller, and this can cause the page table     leaked: BUG: Bad page state in process sh pfn:109324 page: refcount:0 mapcount:0 mapping:0000000000000000     index:0x66 pfn:0x109324 flags: 0x17ffff800000000(node=0|zone=2|lastcpupid=0xfffff) page_type: f2(table)     raw: 017ffff800000000 0000000000000000 0000000000000000 0000000000000000 raw: 0000000000000066     0000000000000000 00000000f2000000 0000000000000000 page dumped because: nonzero mapcount ...

    1. The page table itself will be discarded after reporting the nonzero mapcount. 2. The HugeTLB page     mapped by the page table miss freeing since we treat the page table as shared and a shared page table will     not be unmapped. Fix it by introducing independent PMD page table shared count. As described by comment,     pt_index/pt_mm/pt_frag_refcount are used for s390 gmap, x86 pgds and powerpc, pt_share_count is used for     x86/arm64/riscv pmds, so we can reuse the field as pt_share_count.

  - bonding: fix use-after-free due to enslave fail after slave array update Fix a use-after-free which     happens due to enslave failure after the new slave has been added to the array. Since the new slave can be     used for Tx immediately, we can use it after it has been freed by the enslave error cleanup path which     frees the allocated slave memory. Slave update array is supposed to be called last when further enslave     failures are not expected. Move it after xdp setup to avoid any problems. It is very easy to reproduce the     problem with a simple xdp_pass prog: ip l add bond1 type bond mode balance-xor ip l set bond1 up ip l set     dev bond1 xdp object xdp_pass.o sec xdp_pass ip l add dumdum type dummy Then run in parallel: while :; do     ip l set dumdum master bond1 1>/dev/null 2>&1; done; mausezahn bond1 -a own -b rand -A rand -B 1.1.1.1 -c     0 -t tcp dp=1-1023, flags=syn The crash happens almost immediately: [ 605.602850] Oops: general     protection fault, probably for non-canonical address 0xe0e6fc2460000137: 0000 [#1] SMP KASAN NOPTI [     605.602916] KASAN: maybe wild-memory-access in range [0x07380123000009b8-0x07380123000009bf] [ 605.602946]     CPU: 0 UID: 0 PID: 2445 Comm: mausezahn Kdump: loaded Tainted: G B 6.19.0-rc6+ #21 PREEMPT(voluntary) [     605.602979] Tainted: [B]=BAD_PAGE [ 605.602998] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS     1.16.3-debian-1.16.3-2 04/01/2014 [ 605.603032] RIP: 0010:netdev_core_pick_tx+0xcd/0x210 [ 605.603063]     Code: 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 3e 01 00 00 48 b8 00 00 00 00 00 fc ff df 4c 8b 6b 08 49 8d     7d 30 48 89 fa 48 c1 ea 03 <80> 3c 02 00 0f 85 25 01 00 00 49 8b 45 30 4c 89 e2 48 89 ee 48 89 [     605.603111] RSP: 0018:ffff88817b9af348 EFLAGS: 00010213 [ 605.603145] RAX: dffffc0000000000 RBX:
