Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2022-2873)

The vulnerability allows a local user to crash the kernel.

The vulnerability exists due to a boundary condition within the Intel iSMT SMBus host controller driver. A local user can send specially crafted data to the I2C_SMBUS IOCTL, trigger an out-of-bounds read error and crash the system.


2) Resource management error (CVE-ID: CVE-2022-3903)

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an incorrect read request flaw in the Infrared Transceiver USB driver in Linux kernel. An attacker with physical access to the system can starve system resources and perform a denial of service (DoS) attack.


3) NULL pointer dereference (CVE-ID: CVE-2022-3104)

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 lkdtm_ARRAY_BOUNDS() function in drivers/misc/lkdtm/bugs.c. A local user can perform a denial of service (DoS) attack.


4) NULL pointer dereference (CVE-ID: CVE-2022-3111)

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 free_charger_irq() function in drivers/power/supply/wm8350_power.c. A local user can perform a denial of service (DoS) attack.


5) NULL pointer dereference (CVE-ID: CVE-2022-3107)

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 netvsc_get_ethtool_stats() function in drivers/net/hyperv/netvsc_drv.c. A local user can perform a denial of service (DoS) attack.


6) NULL pointer dereference (CVE-ID: CVE-2022-3112)

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 amvdec_set_canvases() function in drivers/staging/media/meson/vdec/vdec_helpers.c. A local user can perform a denial of service (DoS) attack.


7) NULL pointer dereference (CVE-ID: CVE-2022-3113)

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 mtk_vcodec_fw_vpu_init() function in drivers/media/platform/mtk-vcodec/mtk_vcodec_fw_vpu.c. A local user can perform a denial of service (DoS) attack.


8) NULL pointer dereference (CVE-ID: CVE-2022-3115)

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 malidp_crtc_reset() function in drivers/gpu/drm/arm/malidp_crtc.c. A local user can perform a denial of service (DoS) attack.


9) NULL pointer dereference (CVE-ID: CVE-2022-3114)

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 the imx_register_uart_clocks() function in drivers/clk/imx/clk.c. A local user can perform a denial of service (DoS) attack.


10) Improper Initialization (CVE-ID: CVE-2022-2196)

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

The vulnerability exists due to improper initialization within nVMX in Linux kernel. A local user can perform speculative execution attacks and escalate privileges on the system.


11) Heap-based buffer overflow (CVE-ID: CVE-2022-47942)

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in set_ntacl_dacl, related to use of SMB2_QUERY_INFO_HE after a malformed SMB2_SET_INFO_HE command. A remote user can send specially crafted data to the ksmbd daemon, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


12) Out-of-bounds read (CVE-ID: CVE-2022-47940)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in smb2_write in fs/ksmbd/smb2pdu.c. A remote user can trigger an out-of-bounds read error and read contents of memory on the system.


13) Out-of-bounds read (CVE-ID: CVE-2022-47943)

The vulnerability allows a remote user to perform a denial of service attack.

The vulnerability exists due to an out-of-bounds read in ksmbd due to a large length in the zero DataOffset case in SMB2_WRITE call. A remote user can send specially crafted request to the ksmbd daemon, trigger an out-of-bounds write error and perform a denial of service (DoS) attack.
