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...

kernel: ext4: set goal start correctly in ext4_mb_normalize_request

A flaw was found in the Linux kernel's ext4 filesystem block allocator. In ext4mbnormalizerequest, the goal start was being set incorrectly acfex instead of acgex, and boundary validation was missing. Without proper range checking, an underflow in ar-pright - size could pass an invalid value to...
