A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information.

In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Harden accesses to the reset domains
Accessing reset domains descriptors by the index upon the SCMI drivers requests through the SCMI reset operations interface can potentially lead to out-of-bound violations if the SCMI driver misbehave.
Add an internal consistency check before any such domains descriptors accesses. In the Linux kernel, the following vulnerability has been resolved:
media: lgdt3306a: Add a check against null-pointer-def
The driver should check whether the client provides the platform_data.

Affected: openEuler:22.03-LTS-SP1: kernel
The Linux Kernel, the operating system core itself. Security Fix(es): In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2023-21255) (CVE-2023-2163) A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_TREE_CONNECT and SMB2_QUERY_INFO commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.(CVE-2023-32248) VUL-0: CVE-2023-32255: kernel: Linux Kernel ksmbd Session Setup Memory Leak Denial-of-Service Vulnerability(CVE-2023-32255) A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel.
