CVE-2022-49090

The CVE-2022-49090 entry concerns Linux kernel arch/arm64: Fix topology initialization for core scheduling. The issue arises when store_cpu_topology() does not call update_siblings_masks() before notify_cpu_starting(), causing core scheduling data structures to reflect an incorrect topology. If s...

CVE-2022-49090

In the Linux kernel, the following vulnerability has been resolved: arch/arm64: Fix topology initialization for core scheduling Arm64 systems rely on storecputopology to call updatesiblingsmasks to transfer the toplogy to the various cpu masks. This needs to be done before the call to...

CVE-2022-49081

Summary (CVE-2022-49081) : Linux kernel vulnerability in highmem handling (__kmap_local_sched_in/out). When CONFIG_DEBUG_KMAP_LOCAL is enabled, checks on tsk->kmap_ctrl.pteval could misinterpret zeroed slots as unmapped, triggering runtime warnings. The root cause is comparing to pte_none for ...
