CVE-2024-53109: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: nommu: pass NULL argument to vma_iter_prealloc() When deleting a vma entry from a maple tree, it has to pass NULL to vma_iter_prealloc() 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 acct_collect() reading the size of vma entries after do_munmap(). This commit fixes this issue by passing a right argument to the preallocation call.

Affected products

• Linux Linux Kernel: from 6.6, before 6.6.63 (fixed in 6.6.63); from 6.7, before 6.11.10 (fixed in 6.11.10); version 6.12 only
