An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system.

An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system.

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.

The following log reveals it:
