CVE-2024-26983

CVE-2024-26983 is a Linux kernel issue about freeing xbc memory in bootconfig. The root cause was memblock_free() being used during xbc_exit() when memory may have already been handed to the buddy allocator, causing use-after-free (UAF) on certain architectures (e.g., CONFIG_ARCH_KEEP_MEMBLOCK di...

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...
