Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) 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.
2) 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.
3) Resource exhaustion (CVE-ID: CVE-2023-32247)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to ksmbd does not properly control consumption of internal resources when handling SMB2_SESSION_SETUP commands. A remote attacker can send specially crafted data to the server during session setup, trigger memory exhaustion and perform a denial of service (DoS) attack.
4) 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.
5) NULL pointer dereference (CVE-ID: CVE-2023-46343)
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 send_acknowledge() function in net/nfc/nci/spi.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
6) NULL pointer dereference (CVE-ID: CVE-2023-46862)
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 io_uring_show_fdinfo() function in io_uring/fdinfo.c. A local user can trigger a race with SQ thread exit and perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2023-51779)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error when handling bt_sock_ioctl in the Bluetooth subsystem. A local user can trigger a use-after-free error and execute arbitrary code on the system.
8) Race condition (CVE-ID: CVE-2023-51782)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the Amateur Radio X.25 PLP (Rose) support. A local user can exploit the race and escalate privileges on the system.
9) Out-of-bounds read (CVE-ID: CVE-2023-6121)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the NVMe-oF/TCP subsystem in the Linux kernel. A remote attacker can send specially crafted data to the system, trigger an out-of-bounds read error and read contents of memory.
10) Improper Initialization (CVE-ID: CVE-2024-0340)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to improper initialization within the vhost_new_msg() function in drivers/vhost/vhost.c in the Linux kernel vhost driver. A local user can run a specially crafted application to gain access to sensitive kernel information.
11) Resource management error (CVE-ID: CVE-2024-0607)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the nft_byteorder_eval() function in the Netfilter subsystem. A local user can perform a denial of service (DoS) attack.
12) Use-after-free (CVE-ID: CVE-2024-1085)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the netfilter nf_tables component in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code on the system.
13) Use-after-free (CVE-ID: CVE-2024-1086)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the netfilter nf_tables component in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code on the system.
14) Race condition (CVE-ID: CVE-2024-24855)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the lpfc_unregister_fcf_rescan() function in scsi device driver. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
