A flaw was found in vringh_kiov_advance in drivers/vhost/vringh.c in the host side of a virtio ring in the Linux Kernel. This issue may result in a denial of service from guest to host via zero length descriptor.

An update of the linux package has been released.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6635-1 advisory.

  - An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did     not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN)     attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. (CVE-2023-39189)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

  - A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was     assumed to be associated with a device before calling __ip_options_compile, which is not always the case     if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash     the system. (CVE-2023-42754)

  - A flaw was found in vringh_kiov_advance in drivers/vhost/vringh.c in the host side of a virtio ring in the     Linux Kernel. This issue may result in a denial of service from guest to host via zero length descriptor.
    (CVE-2023-5158)

  - A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a     logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause     a use-after-free and double-free problem, which may permit remote code execution or lead to local     privilege escalation. (CVE-2023-5178)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an     event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory     locations outside of the allocated buffer. We recommend upgrading past commit     32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

  - An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
    (CVE-2023-6606)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The function nft_pipapo_walk did not skip inactive elements during set     walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-     after-free. We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a. (CVE-2023-6817)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap     out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit     382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

  - A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on     a RCU read locked object which is freed by another thread. We recommend upgrading past commit     e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

  - A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is     garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a     use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with     CAP_NET_ADMIN capability to escalate their privileges on the system. (CVE-2024-0193)

  - An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of     XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data     to userspace. (CVE-2023-3773)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did     not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN)     attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. (CVE-2023-39189)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

  - A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing     of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local     privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an     information disclosure. (CVE-2023-39194)

  - A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function     dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one     holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a     use-after-free issue, potentially leading to a denial of service or privilege escalation. (CVE-2023-39198)

  - A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was     assumed to be associated with a device before calling __ip_options_compile, which is not always the case     if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash     the system. (CVE-2023-42754)

  - A flaw was found in vringh_kiov_advance in drivers/vhost/vringh.c in the host side of a virtio ring in the     Linux Kernel. This issue may result in a denial of service from guest to host via zero length descriptor.
