[PATCH OLK-6.6] net: bridge: fix soft lockup in br_multicast_query_expired()
by Bowen You 19 Sep '25
by Bowen You 19 Sep '25
19 Sep '25
From: Wang Liang <wangliang74(a)huawei.com>
mainline inclusion
from mainline-v6.12-rc1
commit d1547bf460baec718b3398365f8de33d25c5f36f
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICXMCM
CVE: CVE-2025-39773
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
When set multicast_query_interval to a large value, the local variable
'time' in br_multicast_send_query() may overflow. If the time is smaller
than jiffies, the timer will expire immediately, and then call mod_timer()
again, which creates a loop and may trigger the following soft lockup
issue.
watchdog: BUG: soft lockup - CPU#1 stuck for 221s! [rb_consumer:66]
CPU: 1 UID: 0 PID: 66 Comm: rb_consumer Not tainted 6.16.0+ #259 PREEMPT(none)

__irq_exit_rcu+0x158/0x1a0
sysvec_apic_timer_interrupt+0x76/0x90
</IRQ>
This issue can be reproduced with:
ip link add br0 type bridge
echo 1 > /sys/class/net/br0/bridge/multicast_querier
echo 0xffffffffffffffff >
/sys/class/net/br0/bridge/multicast_query_interval
ip link set dev br0 up
The multicast_startup_query_interval can also cause this issue. Similar to
the commit 99b40610956a ("net: bridge: mcast: add and enforce query
interval minimum"), add check for the query interval maximum to fix this
issue.

[PATCH openEuler-1.0-LTS] scsi: target: iscsi: Fix a race condition between login_work and the login thread

commit fec1b2fa62c162d03f5dcd7b03e3c89d3116d49f
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICYBVS
CVE: CVE-2022-50350
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
In case a malicious initiator sends some random data immediately after a
login PDU; the iscsi_target_sk_data_ready() callback will schedule the
login_work and, at the same time, the negotiation may end without clearing
the LOGIN_FLAGS_INITIAL_PDU flag (because no additional PDU exchanges are
required to complete the login).
The login has been completed but the login_work function will find the
LOGIN_FLAGS_INITIAL_PDU flag set and will never stop from rescheduling
itself; at this point, if the initiator drops the connection, the
iscsit_conn structure will be freed, login_work will dereference a released
socket structure and the kernel crashes.
BUG: kernel NULL pointer dereference, address: 0000000000000230
PF: supervisor write access in kernel mode
PF: error_code(0x0002) - not-present page
Workqueue: events iscsi_target_do_login_rx [iscsi_target_mod]
RIP: 0010:_raw_read_lock_bh+0x15/0x30
Call trace:
iscsi_target_do_login_rx+0x75/0x3f0 [iscsi_target_mod]
process_one_work+0x1e8/0x3c0
Fix this bug by forcing login_work to stop after the login has been
completed and the socket callbacks have been restored.
Add a comment to clearify the return values of iscsi_target_do_login()

CVE: CVE-2025-39819
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
A possible inconsistent update of refcount was identified in `smb2_compound_op`.
Such inconsistent update could lead to possible resource leaks.
Why it is a possible bug:
1. In the comment section of the function, it clearly states that the
reference to `cfile` should be dropped after calling this function.
2. Every control flow path would check and drop the reference to
`cfile`, except the patched one.
3. Existing callers would not handle refcount update of `cfile` if
-ENOMEM is returned.
To fix the bug, an extra goto label "out" is added, to make sure that the
cleanup logic would always be respected. As the problem is caused by the
allocation failure of `vars`, the cleanup logic between label "finished"
and "out" can be safely ignored. According to the definition of function
`is_replayable_error`, the error code of "-ENOMEM" is not recoverable.
Therefore, the replay logic also gets ignored.

This happens because sata_pmp_init_links() initialize link->pmp up to
SATA_PMP_MAX_PORTS while em_priv is declared as 8 elements array.
I can't find the maximum Enclosure Management ports specified in AHCI
spec v1.3.1, but "12.2.1 LED message type" states that "Port Multiplier
Information" can utilize 4 bits, which implies it can support up to 16
ports. Hence, use SATA_PMP_MAX_PORTS as EM_MAX_SLOTS to resolve the
issue.

[PATCH OLK-6.6 v3] arm64: Do not enable hardware xcall/xint in guest temporarily
by Jinjie Ruan 18 Sep '25
by Jinjie Ruan 18 Sep '25
18 Sep '25
hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/release-management/issues/IBV2E4
--------------------------------
In guest VM, ID register is needed to do VM migration, but currently 920G
do not have an ID register to identify hardware xcall/xint feature, which
will be supported by AIDR_EL1.xcall in the next generation, so check
the bit for non-920G hardware and do not enable xcall/xint in guest
for 920G to avoid the problem in guest.
Fixes: 7f2e02718bba ("arm64: entry: Support hardware xcall and xint")
