Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-2002)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper permissions check in the Bluetooth subsystem when handling ioctl system calls of HCI sockets. A local user can acquire a trusted socket, leading to unauthorized execution of management commands.
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) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2023-3006)
The vulnerability allow a local user to gain access to sensitive information.
The vulnerability exists due to a known cache speculation vulnerability (Spectre-BHB) for the new hw AmpereOne. A local user can gain access to sensitive information.
4) Out-of-bounds read (CVE-ID: CVE-2023-34256)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within crc16 in lib/crc16.c when called from fs/ext4/super.c. A local user can trigger an out-of-bounds read error and crash the kernel.
5) Out-of-bounds read (CVE-ID: CVE-2023-39197)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the Netfilter Connection Tracking (conntrack) in the Linux kernel in the nf_conntrack_dccp_packet() function in net/netfilter/nf_conntrack_proto_dccp.c. A remote attacker can send specially crafted DCCP packets to the system, trigger an out-of-bounds read error and read contents of memory on the system.
6) 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.
7) Input validation error (CVE-ID: CVE-2023-46838)
The vulnerability allows an unprivileged guest to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of network packets at the backend. An unprivileged guest can send zero-length packets to the OS kernel and perform a denial of service (DoS) attack.
8) Race condition (CVE-ID: CVE-2023-51781)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the Appletalk subsystem in Linux kernel. 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) Use-after-free (CVE-ID: CVE-2024-0775)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the __ext4_remount() function in fs/ext4/super.c in ext4. A local user can trigger a use-after-free error and execute arbitrary code on the system.
11) 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.
12) 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.
