Unity Linux 20.1070e Security Update: kernel (UTSA-2025-989628)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989628 advisory. In the Linux kernel, the following vulnerability has been resolved: mm: prevent derefencing NULL ptr in pfnsectionvalid Commit 5ec8e8ea8b77 mm/sparsemem: fix race in...
kernel: mm/sparsemem: fix race in accessing memory_section->usage
A race condition was found on a PFN in the Linux Kernel, which can fall into the device memory region with the system memory configuration. Normal zone start and end PFNs contain the device memory PFNs as well, and the compaction triggered will try on the device memory PFNs and end up in NOP. Thi...
kernel: mm: prevent derefencing NULL ptr in pfn_section_valid()
A flaw was found in the Linux kernel. This flaw allows a local user to cause a Denial of Service DoS by crashing the system. A race condition during memory section deactivation in the memory management subsystem can lead to a null pointer dereference in the pfnsectionvalid function due to a missi...
