[PATCH openEuler-1.0-LTS] scsi: target: iscsi: Fix a race condition between login_work and the login thread
by Yifan Qiao 18 Sep '25

18 Sep '25

From: Maurizio Lombardi <mlombard(a)redhat.com> mainline inclusion from mainline-v6.2-rc1 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.

[PATCH OLK-6.6] fs/smb: Fix inconsistent refcnt update
by Yifan Qiao 18 Sep '25

18 Sep '25

From: Shuhao Fu <sfual(a)cse.ust.hk> mainline inclusion from mainline-v6.17-rc4 commit ab529e6ca1f67bcf31f3ea80c72bffde2e9e053e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICYBJ5 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.

[PATCH OLK-6.6 v3] arm64: Do not enable hardware xcall/xint in guest temporarily
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.

[PATCH OLK-6.6] vsock/virtio: Validate length in packet header before skb_put()
by Ziming Du 17 Sep '25

17 Sep '25

From: Will Deacon <will(a)kernel.org> mainline inclusion from mainline-v6.17-rc1 commit 0dab92484474587b82e8e0455839eaf5ac7bf894 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWO1M CVE: CVE-2025-39718 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately, virtio_vsock_skb_rx_put() uses the length from the packet header as the length argument to skb_put(), potentially resulting in SKB overflow if the host has gone wonky. Validate the length as advertised by the packet header before calling virtio_vsock_skb_rx_put().
