In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: install stub fence into potential unused fence pointers When using cpu to update page tables, vm update fences are unused. Install stub fence into these fence pointers instead of NULL to avoid NULL dereference when...

CVE-2022-50296 UM: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK

In the Linux kernel, the following vulnerability has been resolved: UM: cpuinfo: Fix a warning for CONFIGCPUMASKOFFSTACK When CONFIGCPUMASKOFFSTACK and CONFIGDEBUGPERCPUMAPS is selected, cpumaxbitswarn generates a runtime warning similar as below while we show /proc/cpuinfo. Fix this by using...

CVE-2022-50296

CVE-2022-50296 affects the Linux kernel where cpu_max_bits_warn() would warn when CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are enabled while displaying /proc/cpuinfo. The root cause is using NR_CPUS to iterate CPUs instead of the runtime limit nr_cpu_ids, which leads to a runtime war...
