CVE-2026-46281

In the Linux kernel, the following vulnerability has been resolved: vmalloc: fix buffer overflow in vreallocnodealign Commit 4c5d3365882d "mm/vmalloc: allow to set node and align in vrealloc" added the ability to force a new allocation if the current pointer is on the wrong NUMA node, or if an...

CVE-2026-46281

The CVE affects the Linux kernel vmalloc path. A buffer overflow could occur in vrealloc_node_align() when reallocating with shrinking, because old_size bytes could be copied into a newly allocated buffer of size 'size' before the fix. The issue arises during need_realloc when a new object is all...
