Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) 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.
2) Use-after-free (CVE-ID: CVE-2023-1829)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the tcindex_delete() function. A local user can trigger a use-after-free error and execute arbitrary code with root privileges.
3) Improper locking (CVE-ID: CVE-2023-2430)
The vulnerability allows a local user to perform a denial of service attack (DoS).
The vulnerability exists due to improper locking within the io_uring subsystem in Linux kernel when IOPOLL mode is being
used. A local user can crash the kernel.
4) Out-of-bounds read (CVE-ID: CVE-2023-28866)
The vulnerability allows an attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in net/bluetooth/hci_sync.c in Linux kernel. An attacker with physical proximity to device can trigger an out-of-bounds read error and read contents of memory on the system.
5) Out-of-bounds write (CVE-ID: CVE-2023-3090)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the ipvlan network driver in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
6) Use-after-free (CVE-ID: CVE-2023-3111)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the prepare_to_relocate() function in fs/btrfs/relocation.c in btrfs in the Linux Kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
7) NULL pointer dereference (CVE-ID: CVE-2023-3212)
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 gfs2 file system in the Linux kernel. A local user can perform a denial of service (DoS) attack.
8) NULL pointer dereference (CVE-ID: CVE-2023-3220)
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 dpu_crtc_atomic_check() function in drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c. A local user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
9) NULL pointer dereference (CVE-ID: CVE-2023-3357)
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 the Linux kernel AMD Sensor Fusion Hub driver. A local user can perform a denial of service (DoS) attack.
10) NULL pointer dereference (CVE-ID: CVE-2023-3358)
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 the Linux kernel's Integrated Sensor Hub (ISH) driver. A local user and perform a denial of service (DoS) attack.
11) Use-after-free (CVE-ID: CVE-2023-3389)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the Linux Kernel io_uring subsystem. A local user can exploit a race condition and execute arbitrary code with elevated privileges.
12) Out-of-bounds write (CVE-ID: CVE-2023-35788)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the fl_set_geneve_opt() function in net/sched/cls_flower.c in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
13) Race condition (CVE-ID: CVE-2023-35823)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the saa7134_finidev() function in drivers/media/pci/saa7134/saa7134-core.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
14) Race condition (CVE-ID: CVE-2023-35828)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the renesas_usb3_remove() function in drivers/usb/gadget/udc/renesas_usb3.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
15) Use-after-free (CVE-ID: CVE-2023-35829)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the rkvdec_remove() function in drivers/staging/media/rkvdec/rkvdec.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
