SUSE CVE-2021-47632

In the Linux kernel, the following vulnerability has been resolved: powerpc/setmemory: Avoid spinlock recursion in changepageattr Commit 1f9ad21c3b38 "powerpc/mm: Implement setmemory routines" included a spinlock to changepageattr in order to safely perform the three step operations. But then...

CVE-2021-47632

CVE-2021-47632 affects the Linux kernel on PowerPC where a spin_lock in change_page_attr() for set_memory caused spinlock recursion. The fix removes the read/modify/write sequence and the spin_lock(), and uses atomic handling of page-flag sets (_PAGE_KERNEL_RO/ROX/RW/RWX) by comparing flag sets t...
