CVE-2023-5178

A use-after-free vulnerability was found in drivers/nvme/target/tcp.cinnvmet_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.

The Linux Kernel, the operating system core itself.

Security Fix(es):

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)

An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.(CVE-2023-46813)

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 use-after-free vulnerability was found in drivers/nvme/target/tcp.cinnvmet_tcp_free_crypto` due to a logical bug in the NVMe-oF/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 in case that the attacker already has local privileges.(CVE-2023-5178)

This kernel update is based on upstream 6.5.11 and fixes or adds mitigations for at least the following security issues:

A use-after-free vulnerability was found in drivers/nvme/target/tcp.cinnvmet_tcp_free_crypto` due to a logical bug in the NVMe-oF/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 in case that the attacker already has local privileges. (CVE-2023-5178)

x86: KVM: SVM: always update the x2avic msr interception: The following problem exists since x2avic was enabled in the KVM: svm_set_x2apic_msr_interception is called to enable the interception of the x2apic msrs. In particular it is called at the moment the guest resets its apic. Assuming that the guest's apic is in x2apic mode, the reset will bring it back to the xapic mode. The svm_set_x2apic_msr_interception however has an erroneous check for '!apic_x2apic_mode()' which prevents it from doing anything in this case. As a result of this, all x2apic msrs are left unintercepted, and that exposes the bare metal x2apic (if enabled) to the guest. Removing the erroneous '!apic_x2apic_mode()' check fixes that. (CVE-2023-5090)

In unprivileged Xen guests event handling can cause a deadlock with Xen console handling. The evtchn_rwlock and the hvc_lock are taken in opposite sequence in __hvc_poll() and in Xen console IRQ handling. This is fixed by xen/events: replace evtchn_rwlock with RCU (CVE-2023-34324)

A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705 (CVE-2023-5345)

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)

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)

An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it. (CVE-2023-46813)

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)
