Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2022-36280)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the vmw_kms_cursor_snoo() function in drivers/gpu/vmxgfx/vmxgfx_kms.c in vmwgfx VMWare driver. A local user can trigger an out-of-bounds write and perform a denial of service (DoS) attack.


2) NULL pointer dereference (CVE-ID: CVE-2022-38096)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. A local user can perform a denial of service (DoS) attack.


3) Security features bypass (CVE-ID: CVE-2023-0045)

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to Linux kernel does not correctly mitigate SMT attacks. A local user can bypass Spectre-BTI user space mitigations and gain access to sensitive information.


4) Use-after-free (CVE-ID: CVE-2023-0590)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the qdisc_graft() function in net/sched/sch_api.c. A local user can trigger a use-after-free error and crash the kernel.


5) Memory leak (CVE-ID: CVE-2023-0597)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to memory leak within the Linux kernel cpu_entry_area mapping of X86 CPU data. A local user can gain access to sensitive information.


6) Use-after-free (CVE-ID: CVE-2023-1118)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error in the Linux kernel integrated infrared receiver/transceiver driver "drivers/media/rc/ene_ir.c" when detaching rc device. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.



7) Input validation error (CVE-ID: CVE-2023-22995)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient validation of user-supplied input within the dwc3_qcom_acpi_register_core() function in drivers/usb/dwc3/dwc3-qcom.c. A local user can execute arbitrary code on the system with elevated privileges.


8) NULL pointer dereference (CVE-ID: CVE-2023-23000)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the tegra_xusb_find_port_node() function in drivers/phy/tegra/xusb.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.


9) NULL pointer dereference (CVE-ID: CVE-2023-23006)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the mlx5_get_uars_page() function in drivers/net/ethernet/mellanox/mlx5/core/steering/dr_domain.c. A local user can pass specially crafted data to the systen and perform a denial of service (DoS) attack.


10) Integer overflow (CVE-ID: CVE-2023-23559)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow within the rndis_query_oid() function in drivers/net/wireless/rndis_wlan.c. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.


11) Double Free (CVE-ID: CVE-2023-26545)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a double free in net/mpls/af_mpls.c during the renaming of a device. A local user can trigger a double free error and execute arbitrary code with elevated privileges.
