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-2024-26974

CVE-2024-26974 affects the Linux kernel crypto/qat driver. A race during PCI AER error recovery could cause a use-after-free of the reset_data container used for completion notification after a device restart, triggering a KFENCE use-after-free notice. The fix alters memory lifetime: the containe...
