A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC bundles. This issue results from the lack of proper locking when performing operations on an object. This may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel.

An update of the linux package has been released.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4730-1 advisory.

  - A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC     bundles. This issue results from the lack of proper locking when performing operations on an object. This     may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel.
    (CVE-2023-2006)

  - Improper access control in the Intel(R) Ethernet Controller RDMA driver for linux before version 1.9.30     may allow an unauthenticated user to potentially enable escalation of privilege via network access.
    (CVE-2023-25775)

  - 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 use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane     transaction and nft_set element garbage collection, it is possible to underflow the reference counter     causing a use-after-free vulnerability. We recommend upgrading past commit     3e91b0ebd994635df2346353322ac51ce84ce6d8. (CVE-2023-4244)

  - An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker     can trigger a race condition that results in a fill_kobj_path out-of-bounds write. (CVE-2023-45863)

  - An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

  - An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an     io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

  - 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)

  - The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-     after-free flaw in the way memory objects were handled when they were being used to store a surface. When     running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially     use this flaw to escalate their privileges. (CVE-2023-5633)

  - 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)

  - A use-after-free flaw was found in lan78xx_disconnect in drivers/net/usb/lan78xx.c in the network sub-     component, net/usb/lan78xx in the Linux Kernel. This flaw allows a local attacker to crash the system when     the LAN78XX USB device detaches. (CVE-2023-6039)

  - A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm     scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific     socket configuration, which could allow a local user to crash the system or escalate their privileges on     the system. (CVE-2023-6176)
