Debian DLA	DLA-4076-1	linux-6.1 security update
EUVD	EUVD-2024-53424	In the Linux kernel, the following vulnerability has been resolved: powerpc/prom_init: Fixup missing powermac #size-cells On some powermacs `escc` nodes are missing `#size-cells` properties, which is deprecated and now triggers a warning at boot since commit 045b14ca5c36 ("of: WARN on deprecated #address-cells/#size-cells handling"). For example: Missing '#size-cells' in /pci@f2000000/mac-io@c/escc@13000 WARNING: CPU: 0 PID: 0 at drivers/of/base.c:133 of_bus_n_size_cells+0x98/0x108 Hardware name: PowerMac3,1 7400 0xc0209 PowerMac ...
