- Summary
- CVE-2024-53109 affecting package kernel for versions less than 6.6.64.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nommu: pass NULL argument to vmaiterprealloc()
When deleting a vma entry from a maple tree, it has to pass NULL to vmaiterprealloc() in order to calculate internal state of the tree, but it passed a wrong argument. As a result, nommu kernels crashed upon accessing a vma iterator, such as acctcollect() reading the size of vma entries after domunmap().
This commit fixes this issue by passing a right argument to the preallocation call.
