In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: avoid disabling offload when it was never enabled In an incredibly strange API design decision, qdisc->destroy() gets called even if qdisc->init() never succeeded, not exclusively since commit 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation"), but apparently also earlier (in the case of qdisc_create_dflt()). The taprio qdisc does not fully acknowledge this when it attempts full offload, because it starts off with q->flags = TAPRIO_FLAGS_INVALID in taprio_init(), then it replaces q->flags with TCA_TAPRIO_ATTR_FLAGS parsed from netlink (in taprio_change(), tail called from taprio_init()). But in taprio_destroy(), we call taprio_disable_offload(), and this determines what to do based on FULL_OFFLOAD_IS_ENABLED(q->flags). But looking at the implementation of FULL_OFFLOAD_IS_ENABLED() (a bitwise check of bit 1 in q->flags), it is invalid to call this macro on q->flags when it contains TAPRIO_FLAGS_INVALID, because that is set to U32_MAX, and therefore FULL_OFFLOAD_IS_ENABLED() will return true on an invalid set of flags. As a result, it is possible to crash the kernel if user space forces an error between setting q->flags = TAPRIO_FLAGS_INVALID, and the calling of taprio_enable_offload(). This is because drivers do not expect the offload to be disabled when it was never enabled. The error that we force here is to attach taprio as a non-root qdisc, but instead as child of an mqprio root qdisc: $ tc qdisc add dev swp0 root handle 1: \ mqprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0 $ tc qdisc replace dev swp0 parent 1:1 \ taprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 base-time 0 \ sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \ flags 0x0 clockid CLOCK_TAI Unable to handle kernel paging request at virtual address fffffffffffffff8 [fffffffffffffff8] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 96000004 [#1] PREEMPT SMP Call trace: taprio_dump+0x27c/0x310 vsc9959_port_setup_tc+0x1f4/0x460 felix_port_setup_tc+0x24/0x3c dsa_slave_setup_tc+0x54/0x27c taprio_disable_offload.isra.0+0x58/0xe0 taprio_destroy+0x80/0x104 qdisc_create+0x240/0x470 tc_modify_qdisc+0x1fc/0x6b0 rtnetlink_rcv_msg+0x12c/0x390 netlink_rcv_skb+0x5c/0x130 rtnetlink_rcv+0x1c/0x2c Fix this by keeping track of the operations we made, and undo the offload only if we actually did it.

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 5.15.73-48.135. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-009 advisory.

    A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root     (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD     CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

    A flaw was found in the Linux kernel in vDPA with VDUSE backend. There were no checks in VDUSE kernel     driver to ensure the size of the device config space was in line with the features advertised by the VDUSE     userspace application. In case of a mismatch, Virtio drivers config read helpers did not initialize the     memory indirectly passed to vduse_vdpa_get_config() returning uninitialized memory from the stack. Such     memory was not directly propagated to userspace, although under some circumstances it could be printed in     the kernel logs. (CVE-2022-2308)

    A use-after-free flaw was found in the Linux kernel's Unix socket Garbage Collection and io_uring. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2602)

    A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-2978)

    Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver     through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by     zero error. (CVE-2022-3061)

    An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in     drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an     integer overflow and bypassing the size check. After that, because it is used as the third argument to     copy_from_user(), a heap overflow may occur. (CVE-2022-39842)

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel 6.0-rc2. An attacker must first obtain the ability to execute high-privileged code on the     target system in order to exploit this vulnerability. The specific flaw exists within the nft_osf_eval     function. The issue results from the lack of proper initialization of memory prior to accessing it. An     attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the     context of the kernel. Was ZDI-CAN-18540. (CVE-2022-42432)

    drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

    netfilter: nf_tables: fix nft_counters_enabled underflow at nf_tables_addchain() (CVE-2022-48643)

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

    net/sched: taprio: avoid disabling offload when it was never enabled (CVE-2022-48644)

    In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused     by unset skb->mac_header If an AF_PACKET socket is used to send packets through ipvlan and the default     xmit function of the AF_PACKET socket is changed from dev_queue_xmit() to packet_direct_xmit() via     setsockopt() with the option name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and remains     as the initial value of 65535, this may trigger slab-out-of-bounds bugs as following: (CVE-2022-48651)

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

    netfilter: nfnetlink_osf: fix possible bogus match in nf_osf_find() (CVE-2022-48654)

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

    arm64: topology: fix possible overflow in amu_fie_setup() (CVE-2022-48657)

    In the Linux kernel, the following vulnerability has been resolved: mm: slub: fix     flush_cpu_slab()/__free_slab() invocations in task context. Commit 5a836bf6b09f (mm: slub: move     flush_cpu_slab() invocations __free_slab() invocations out of IRQ context) moved all flush_cpu_slab()     invocations to the global workqueue to avoid a problem related with deactivate_slab()/__free_slab() being     called from an IRQ context on PREEMPT_RT kernels. (CVE-2022-48658)

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

    mm/slub: fix to return errno if kmalloc() fails (CVE-2022-48659)

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

    gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully (CVE-2022-48660)

    In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Really move     i915_gem_context.link under ref protection i915_perf assumes that it can use the i915_gem_context     reference to protect its i915->gem.contexts.list iteration. However, this requires that we do not remove     the context from the list until after we drop the final reference and release the struct. If, as     currently, we remove the context from the list during context_close(), the link.next pointer may be     poisoned while we are holding the context reference and cause a GPF (CVE-2022-48662)

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

    btrfs: fix hang during unmount when stopping a space reclaim worker (CVE-2022-48664)

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

    cgroup: Add missing cpus_read_lock() to cgroup_attach_task_all() (CVE-2022-48671)

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

    of: fdt: fix off-by-one error in unflatten_dt_nodes() (CVE-2022-48672)

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

    io_uring/af_unix: defer registered files gc to io_uring release (CVE-2022-50234)

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

    fs: fix UAF/GPF bug in nilfs_mdt_destroy (CVE-2022-50367)

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 5.10.147-133.644. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-021 advisory.

    A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not.  This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

    A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root     (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD     CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

    A vulnerability, which was classified as problematic, was found in Linux Kernel. Affected is the function     damon_sysfs_add_target of the file mm/damon/sysfs.c of the component Netfilter. The manipulation leads to     memory leak. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is     VDB-211044. (CVE-2022-3544)
