Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Improper access control (CVE-ID: CVE-2023-25775)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper access restrictions in the Intel Ethernet Controller RDMA driver for Linux. A remote non-authenticated attacker can bypass implemented security restrictions and gain access to sensitive information.
2) NULL pointer dereference (CVE-ID: CVE-2023-31083)
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 hci_uart_tty_ioctl() function in drivers/bluetooth/hci_ldisc.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
3) Division by zero (CVE-ID: CVE-2023-31085)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a divide by zero error within the drivers/mtd/ubi/cdev.c driver. A local user can perform a denial of service (DoS) attack.
4) NULL pointer dereference (CVE-ID: CVE-2023-3772)
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 xfrm_update_ae_params() function in the IP framework for transforming packets (XFRM subsystem). A local user with CAP_NET_ADMIN privileges can perform a denial of service (DoS) attack.
5) Out-of-bounds read (CVE-ID: CVE-2023-38430)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in ksmbd when handling SMB request protocol ID. A remote attacker can send specially crafted packets to the system to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
6) Out-of-bounds read (CVE-ID: CVE-2023-38432)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in fs/smb/server/smb2misc.c in ksmbd. A remote attacker can send specially crafted packets to the system to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2023-3863)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the nfc_llcp_find_local() function in net/nfc/llcp_core.c in NFC implementation in Linux kernel. A local user can execute arbitrary code with elevated privileges.
8) Out-of-bounds read (CVE-ID: CVE-2023-3865)
The vulnerability allows a remote user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the ksmbd_smb2_check_message() function in fs/smb/server/smb2misc.c when parsing smb2_hdr structure. A remote user can send specially crafted packets to ksmbd, trigger an out-of-bounds read error and read contents of memory or perform a denial of service (DoS) attack.
9) NULL pointer dereference (CVE-ID: CVE-2023-3866)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the void __handle_ksmbd_work() function in fs/smb/server/server.c when handling chained requests. A remote attacker can send specially crafted data to the ksmbd and perform a denial of service (DoS) attack.
10) Out-of-bounds read (CVE-ID: CVE-2023-3867)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the KSMBD implementation in the Linux kernel. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.
11) Use-after-free (CVE-ID: CVE-2023-4132)
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 siano smsusb module in the Linux kernel. A local user can trigger a use-after-free error and crash the kernel.
12) Use-after-free (CVE-ID: CVE-2023-4134)
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 cyttsp4_watchdog_work() in cyttsp4_core driver. A local user can trigger memory corruption and crash the kernel.
13) Buffer overflow (CVE-ID: CVE-2023-44466)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ceph_decode_32() function in net/ceph/messenger_v2.c in the Ceph filesystem when handling TCP packets. A remote attacker can send specially crafted HELLO or AUTH frames to trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Buffer overflow (CVE-ID: CVE-2023-45871)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the IGB driver in drivers/net/ethernet/intel/igb/igb_main.c when handling frames larger than the MTU. A remote attacker can send specially crafted traffic to the system, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
15) Improper handling of exceptional conditions (CVE-ID: CVE-2023-5090)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper handling of errors within the svm_set_x2apic_msr_interception() function in KVM. A local user can send specially crafted input and perform a denial of service (DoS) attack.
16) Use-after-free (CVE-ID: CVE-2023-5345)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the smb3_fs_context_parse_param() function in fs/smb/client component. A remote attacker can execute arbitrary code with elevated privileges.
