In the Linux kernel, the following vulnerability has been resolved: tun: Fix memory leak for detached NAPI queue. syzkaller reported [0] memory leaks of sk and skb related to the TUN device with no repro, but we can reproduce it easily with: struct ifreq ifr = {} int fd_tun, fd_tmp; char buf[4] = {}; fd_tun = openat(AT_FDCWD, "/dev/net/tun", O_WRONLY, 0); ifr.ifr_flags = IFF_TUN | IFF_NAPI | IFF_MULTI_QUEUE; ioctl(fd_tun, TUNSETIFF, &ifr); ifr.ifr_flags = IFF_DETACH_QUEUE; ioctl(fd_tun, TUNSETQUEUE, &ifr); fd_tmp = socket(AF_PACKET, SOCK_PACKET, 0); ifr.ifr_flags = IFF_UP; ioctl(fd_tmp, SIOCSIFFLAGS, &ifr); write(fd_tun, buf, sizeof(buf)); close(fd_tun); If we enable NAPI and multi-queue on a TUN device, we can put skb into tfile->sk.sk_write_queue after the queue is detached. We should prevent it by checking tfile->detached before queuing skb. Note this must be done under tfile->sk.sk_write_queue.lock because write() and ioctl(IFF_DETACH_QUEUE) can run concurrently. Otherwise, there would be a small race window: write() ioctl(IFF_DETACH_QUEUE) `- tun_get_user `- __tun_detach |- if (tfile->detached) |- tun_disable_queue | `-> false | `- tfile->detached = tun | `- tun_queue_purge |- spin_lock_bh(&queue->lock) `- __skb_queue_tail(queue, skb) Another solution is to call tun_queue_purge() when closing and reattaching the detached queue, but it could paper over another problems. Also, we do the same kind of test for IFF_NAPI_FRAGS.

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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tun: Fix memory leak for detached NAPI queue. syzkaller reported [0] memory leaks of sk and skb related to     the TUN device with no repro, but we can reproduce it easily with: struct ifreq ifr = {} int fd_tun,     fd_tmp; char buf[4] = {}; fd_tun = openat(AT_FDCWD, /dev/net/tun, O_WRONLY, 0); ifr.ifr_flags = IFF_TUN     | IFF_NAPI | IFF_MULTI_QUEUE; ioctl(fd_tun, TUNSETIFF, &ifr); ifr.ifr_flags = IFF_DETACH_QUEUE;
    ioctl(fd_tun, TUNSETQUEUE, &ifr); fd_tmp = socket(AF_PACKET, SOCK_PACKET, 0); ifr.ifr_flags = IFF_UP;
    ioctl(fd_tmp, SIOCSIFFLAGS, &ifr); write(fd_tun, buf, sizeof(buf)); close(fd_tun); If we enable NAPI and     multi-queue on a TUN device, we can put skb into tfile->sk.sk_write_queue after the queue is detached. We     should prevent it by checking tfile->detached before queuing skb. Note this must be done under     tfile->sk.sk_write_queue.lock because write() and ioctl(IFF_DETACH_QUEUE) can run concurrently. Otherwise,     there would be a small race window: write() ioctl(IFF_DETACH_QUEUE) `- tun_get_user `- __tun_detach |- if     (tfile->detached) |- tun_disable_queue | `-> false | `- tfile->detached = tun | `- tun_queue_purge |-     spin_lock_bh(&queue->lock) `- __skb_queue_tail(queue, skb) Another solution is to call tun_queue_purge()     when closing and reattaching the detached queue, but it could paper over another problems. Also, we do the     same kind of test for IFF_NAPI_FRAGS.

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-228 advisory.

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

    binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50240)

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

    binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50338)

    A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue     results from the improper handling of user-supplied data, which can lead to an assertion failure. This     flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system.
    (CVE-2023-2156)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)
