CVE-2023-52576 x86/mm, kexec, ima: Use memblock_free_late() from ima_free_kexec_buffer()

In the Linux kernel, the following vulnerability has been resolved: x86/mm, kexec, ima: Use memblockfreelate from imafreekexecbuffer The code calling imafreekexecbuffer runs long after the memblock allocator has already been torn down, potentially resulting in a use after free in...

CVE-2023-52576

CVE-2023-52576 affects the Linux kernel (x86/mm, kexec, ima). The issue was a use-after-free in memblock_isolate_range() caused by calling ima_free_kexec_buffer() after the memblock allocator had been torn down. The fix switches ima_free_kexec_buffer() to memblock_free_late() to avoid the bug. Wi...
