CVE-2023-52631

CVE-2023-52631 affects the Linux kernel NTFS3 path. The issue is a NULL dereference in ntfs_load_attr_list() caused by a 32-bit overflow in size calculation (le32_to_cpu(attr->res.data_size) + 1023), which can yield zero and make kmalloc return ZERO_SIZE_PTR, leading to a crash on memcpy. The ...

CVE-2023-52631

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix an NULL dereference bug The issue here is when this is called from ntfsloadattrlist. The "size" comes from le32tocpuattr-res.datasize so it can't overflow on a 64bit systems but on 32bit systems the "+ 1023" can...

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Clear DMA ops when switching domain Since commit 08a27c1c3ecf "iommu: Add support to change default domain of an iommu group" a user can switch a device between IOMMU and direct DMA through sysfs. This doesn't work for...

CVE-2021-47179

A vulnerability in the Linux kernel's NFSv4 subsystem caused a NULL pointer dereference in pnfsmarkmatchinglsegsreturn. This issue occurred because pnfsreturnlayout passed a NULL pnfslayoutrange argument, which was not checked before dereferencing, leading to a system crash. Mitigation Red Hat ha...
