Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2023-23004)
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 get_sg_table() function in drivers/gpu/drm/arm/malidp_planes.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
2) Use-after-free (CVE-ID: CVE-2023-1249)
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 core dump subsystem in Linux kernel. A local user can trigger a use-after-free error and crash the kernel.
3) NULL pointer dereference (CVE-ID: CVE-2023-28327)
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 unix_diag_get_exact() function in net/unix/diag.c. A local user can perform a denial of service (DoS) attack.
4) NULL pointer dereference (CVE-ID: CVE-2023-28328)
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 az6027 driver in drivers/media/usb/dev-usb/az6027.c in the Linux Kernel. A local user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
5) 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.
6) 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.
7) Buffer overflow (CVE-ID: CVE-2022-48424)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within fs/ntfs3/inode.c in Linux kernel. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
8) Out-of-bounds write (CVE-ID: CVE-2022-48423)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within fs/ntfs3/record.c in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
9) Release of invalid pointer or reference (CVE-ID: CVE-2022-48425)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an invalid kfree in fs/ntfs3/inode.c caused by improper validation of MFT flags before replaying logs. A local user can execute arbitrary code with elevated privileges.
10) Improper Initialization (CVE-ID: CVE-2023-1513)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to improper initialization when calling the KVM_GET_DEBUGREGS ioctl on 32-bit systems. A local user can run a specially crafted application to gain access to sensitive information.
11) Use-after-free (CVE-ID: CVE-2023-1281)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in Linux kernel traffic control index filter (tcindex) when the tcf_exts_exec() function is called with the destroyed tcf_ext. A local user attacker can trigger a use-after-free error and execute arbitrary code with elevated privileges.
