SUSE CVE-2023-52490

In the Linux kernel, the following vulnerability has been resolved: mm: migrate: fix getting incorrect page mapping during page migration When running stress-ng testing, we found below kernel crash after a few hours: Unable to handle kernel NULL pointer dereference at virtual address...

CVE-2023-52490

A page mapping vulnerability was found in the Linux kernel. A call to the pagemapping function during a page migration may return an incorrect file mapping and cause a system crash if another thread is simultaneously attempting to offline the target page that is being migrated. Mitigation...

kernel: use-after-free related to leaf anon_vma double reuse

A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the ismergeableanonvma function continuously forks, using memory operations to trigger an incorrect reuse of leaf anonvma. This issue allows a local attacker to crash the system...
