In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race between quota rescan and disable leading to NULL pointer deref If we have one task trying to start the quota rescan worker while another one is trying to disable quotas, we can end up hitting a race that results in the quota rescan worker doing a NULL pointer dereference. The steps for this are the following: 1) Quotas are enabled; 2) Task A calls the quota rescan ioctl and enters btrfs_qgroup_rescan(). It calls qgroup_rescan_init() which returns 0 (success) and then joins a transaction and commits it; 3) Task B calls the quota disable ioctl and enters btrfs_quota_disable(). It clears the bit BTRFS_FS_QUOTA_ENABLED from fs_info->flags and calls btrfs_qgroup_wait_for_completion(), which returns immediately since the rescan worker is not yet running. Then it starts a transaction and locks fs_info->qgroup_ioctl_lock; 4) Task A queues the rescan worker, by calling btrfs_queue_work(); 5) The rescan worker starts, and calls rescan_should_stop() at the start of its while loop, which results in 0 iterations of the loop, since the flag BTRFS_FS_QUOTA_ENABLED was cleared from fs_info->flags by task B at step 3); 6) Task B sets fs_info->quota_root to NULL; 7) The rescan worker tries to start a transaction and uses fs_info->quota_root as the root argument for btrfs_start_transaction(). This results in a NULL pointer dereference down the call chain of btrfs_start_transaction().

    btrfs: fix race between quota rescan and disable leading to NULL pointer deref

    If we have one task trying to start the quota rescan worker while another     one is trying to disable quotas, we can end up hitting a race that results     in the quota rescan worker doing a NULL pointer dereference. The steps for     this are the following:

    1) Quotas are enabled;

       It calls qgroup_rescan_init() which returns 0 (success) and then joins a        transaction and commits it;

    3) Task B calls the quota disable ioctl and enters btrfs_quota_disable().
       It clears the bit BTRFS_FS_QUOTA_ENABLED from fs_info->flags and calls        btrfs_qgroup_wait_for_completion(), which returns immediately since the        rescan worker is not yet running.
       Then it starts a transaction and locks fs_info->qgroup_ioctl_lock;

    4) Task A queues the rescan worker, by calling btrfs_queue_work();

    5) The rescan worker starts, and calls rescan_should_stop() at the start        of its while loop, which results in 0 iterations of the loop, since        the flag BTRFS_FS_QUOTA_ENABLED was cleared from fs_info->flags by        task B at step 3);

    6) Task B sets fs_info->quota_root to NULL;

    7) The rescan worker tries to start a transaction and uses        fs_info->quota_root as the root argument for btrfs_start_transaction().

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.4.231-137.341. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-042 advisory.

    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

    In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

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

    hfs: fix OOB Read in __hfs_brec_find (CVE-2022-50581)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.

    There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.

    When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket.

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.

    There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.

    When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket.
    The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is     created from the listener, the context is inherited and vulnerable.

    The setsockopt TCP_ULP operation does not require any privilege.

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

    class: fix possible memory leak in __class_register() (CVE-2022-50578)

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

    hfs: fix OOB Read in __hfs_brec_find (CVE-2022-50581)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

    There is a logic error in io_uring's implementation which can be used to trigger a use-after-free     vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the     last io_grab_identity call cannot return false is not true, and in this case the function will use the     init_cred or the previous linked requests identity to do operations instead of using the current identity.
    This can lead to reference counting issues causing use-after-free. We recommend upgrading past version     5.10.161. (CVE-2023-0240)

    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.

    There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.

    When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket.
    The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is     created from the listener, the context is inherited and vulnerable.

    The setsockopt TCP_ULP operation does not require any privilege.

    We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

    efi: rt-wrapper: Add missing include (CVE-2023-21102)

    cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

    atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)
