ALT-PU-2021-3451: package `kernel-image-rpi-def` update to version 5.10.81-alt1

In the Linux kernel, the following vulnerability has been resolved: can: etas_es58x: es58x_rx_err_msg(): fix memory leak in error path In es58x_rx_err_msg(), if can->do_set_mode() fails, the function directly returns without calling netif_rx(skb). This means that the skb previously allocated by alloc_can_err_skb() is not freed. In other terms, this is a memory leak. This patch simply removes the return statement in the error branch and let the function continue. Issue was found with GCC -fanalyzer, please follow the link below for details.

A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected.
