Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2023-1382)
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 net/tipc/topsrv.c within the TIPC protocol implementation in the Linux kernel. A local user can perform a denial of service (DoS) attack.
2) Use-after-free (CVE-ID: CVE-2023-1838)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
3) Security features bypass (CVE-ID: CVE-2023-1998)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to incorrect implementation of the Spectre v2 SMT mitigations, related to calling prctl with PR_SET_SPECULATION_CTRL. An attacker can gain unauthorized access to kernel memory from userspace.
4) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2023-24023)
The vulnerability allows a remote attacker to perform a MitM attack.
The vulnerability exists due to improper verification of cryptographic signature in bluetooth implementation. A remote attacker with physical proximity to the system can perform MitM attack and potentially compromise the system.
5) Use-after-free (CVE-ID: CVE-2023-51043)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in drivers/gpu/drm/drm_atomic.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
6) 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.
7) Improper Check for Unusual or Exceptional Conditions (CVE-ID: CVE-2023-52429)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper error handling within the dm_table_create() function in drivers/md/dm-table.c. A local user can pass specially crafted data to the kernel and perform a denial of service (DoS) attack.
8) Out-of-bounds read (CVE-ID: CVE-2024-23851)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the copy_params() function in drivers/md/dm-ioctl.c. A remote attacker can trigger an out-of-bounds read and perform a denial of service (DoS) attack.
9) NULL pointer dereference (CVE-ID: CVE-2023-6915)
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 ida_free() function in lib/idr.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
10) Improper locking (CVE-ID: CVE-2024-0639)
The vulnerability allows a local user to perform a denial of service attack.
The vulnerability exists due to improper locking within the sctp_auto_asconf_init() function in net/sctp/socket.c. A local user can crash the kernel.
11) Improper validation of array index (CVE-ID: CVE-2023-52603)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of array index within the dtSplitRoot() function in fs/jfs/jfs_dtree.c. A local user can perform a denial of service (DoS) attack.
12) Out-of-bounds write (CVE-ID: CVE-2023-52464)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the thunderx_ocx_com_threaded_isr() function in drivers/edac/thunderx_edac.c. A local user can trigger an out-of-bounds write and execute arbitrary code on the target system.
13) Use-after-free (CVE-ID: CVE-2023-52600)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in fs/jfs/jfs_mount.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
14) Use-after-free (CVE-ID: CVE-2023-52445)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in pvrusb2. A local user can execute arbitrary code with elevated privileges.
15) Out-of-bounds read (CVE-ID: CVE-2023-52451)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the dlpar_memory_remove_by_index() function in arch/powerpc/platforms/pseries/hotplug-memory.c. A local user can trigger an out-of-bounds read and perform a denial of service (DoS) attack.
