Public bug reported: [Impact] The warnings emitted by the kernel when CONFIG_DEBUG_WX is enabled will show an incorrect address, nullifying the value of this config option.
[Test Case] Boot; if a "arm64/mm: Found insecure W+X mapping at address" message appears, confirm it's not in the userspace mapping. [Regression Risk] This is arm64-only code, so regressions would be restricted to arm64. This change is currently present in bionic without any noticed regressions. ** Affects: linux (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: linux (Ubuntu Artful) Importance: Undecided Assignee: dann frazier (dannf) Status: In Progress ** Also affects: linux (Ubuntu Artful) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Artful) Status: New => In Progress ** Changed in: linux (Ubuntu Artful) Assignee: (unassigned) => dann frazier (dannf) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1765850 Title: arm64: fix CONFIG_DEBUG_WX address reporting Status in linux package in Ubuntu: Fix Released Status in linux source package in Artful: In Progress Bug description: [Impact] The warnings emitted by the kernel when CONFIG_DEBUG_WX is enabled will show an incorrect address, nullifying the value of this config option.
