Found In Version: 10.22.33.1
Severity: Standard
Applicable for: Wind River Linux LTS 22
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]x86/mm: Check return value from memblock_phys_alloc_range()[EOL][EOL]At least with CONFIG_PHYSICAL_START=0x100000, if there is < 4 MiB of[EOL]contiguous free memory available at this point, the kernel will crash[EOL]and burn because memblock_phys_alloc_range() returns 0 on failure,[EOL]which leads memblock_phys_free() to throw the first 4 MiB of physical[EOL]memory to the wolves.[EOL][EOL]At a minimum it should fail gracefully with a meaningful diagnostic,[EOL]but in fact everything seems to work fine without the weird reserve[EOL]allocation.
========Wind River Notice========
Almost all system has > 4 MiB of contiguous free memory available in early boot. A corner case, its system has < 4 MiB of contiguous free memory available in early boot. There is no point to fix this CVE, mark it as fix deferred.
