Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Race condition (CVE-ID: CVE-2022-3566)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the tcp_getsockopt() and tcp_setsockopt() functions in net/ipv4/tcp.c, do_ipv6_setsockopt() function in net/ipv6/ipv6_sockglue.c, and tcp_v6_connect() function in net/ipv6/tcp_ipv6.c in Linux kernel. A local user can exploit the race and escalate privileges on the system.
2) Use-after-free (CVE-ID: CVE-2022-45884)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in drivers/media/dvb-core/dvbdev.c in Linux kernel related to dvb_register_device() function dynamically allocating fops. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
3) Use-after-free (CVE-ID: CVE-2022-45885)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in drivers/media/dvb-core/dvb_frontend.c in Linux kernel. A local user can trigger a race condition and execute arbitrary code with elevated privileges.
4) Use-after-free (CVE-ID: CVE-2022-45886)
The vulnerability allows a local user to escalate privileges on the system.
5) Race condition (CVE-ID: CVE-2022-45887)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in drivers/media/usb/ttusb-dec/ttusb_dec.c in Linux kernel. A local user can exploit the race and crash the kernel.
6) Use-after-free (CVE-ID: CVE-2022-45919)
The vulnerability allows a local user to escalate privileges on the system.
7) Type Confusion (CVE-ID: CVE-2023-1077)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a type confusion error within the pick_next_rt_entity() function pick_next_rt_entity(). A local user can trigger a type confusion error and execute arbitrary code with elevated privileges.
8) Out-of-bounds read (CVE-ID: CVE-2023-1380)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the Broadcom Full MAC Wi-Fi driver (brcmfmac.ko). A local user can trigger an out-of-bounds read error and read contents of kernel memory on the system.
9) Out-of-bounds read (CVE-ID: CVE-2023-2176)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the compare_netdev_and_ip() function in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. A local user can trigger an out-of-bounds read error and read contents of memory on the system.
10) Out-of-bounds write (CVE-ID: CVE-2023-2194)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the Linux kernel's SLIMpro I2C device driver. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
11) Race condition (CVE-ID: CVE-2023-2483)
The vulnerability allows an attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in Qualcomm EMAC Gigabit Ethernet Controller. An attacker with physical access to system can remove the device before cleanup in the emac_remove() function is called, trigger a use-after-free error and crash the kernel.
12) Use-after-free (CVE-ID: CVE-2023-2513)
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 filesystem in the way it handled the extra inode size for extended attributes. A local user can trigger a use-after-free error and escalate privileges on the system.
13) Race condition (CVE-ID: CVE-2023-28466)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition caused by a missing lock_sock call within the do_tls_getsockopt() function in net/tls/tls_main.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
14) Deadlock (CVE-ID: CVE-2023-31084)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a deadlock in drivers/media/dvb-core/dvb_frontend.c when a task is in !TASK_RUNNING. A local user can trigger a deadlock and crash the kernel.
15) Out-of-bounds write (CVE-ID: CVE-2023-31436)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the qfq_change_class() function in net/sched/sch_qfq.c when handling the MTU value provided to the QFQ Scheduler. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
16) Use-after-free (CVE-ID: CVE-2023-32269)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in net/netrom/af_netrom.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability requires that the system has netrom routing configured or the attacker must have the CAP_NET_ADMIN capability.
