CVE-2026-53187

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Validate cpuid against nrcpuids in DMAH alloc The cpuid attribute supplied by user space through UVERBSATTRALLOCDMAHCPUID is passed directly to cpumasktestcpu without first verifying that the value is within the valid...

CVE-2026-53187

The CVE-2026-53187 issue affects the Linux kernel RDMA/core: the cpu_id supplied via UVERBS_ATTR_ALLOC_DMAH_CPU_ID is passed to cpumask_test_cpu() without validating it against nr_cpu_ids, leading to an out-of-bounds read of the cpumask bitmap. On kernels built with CONFIG_DEBUG_PER_CPU_MAPS this...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993129 advisory. In the Linux kernel, the following vulnerability has been resolved: UM: cpuinfo: Fix a warning for CONFIGCPUMASKOFFSTACK When CONFIGCPUMASKOFFSTACK and...

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...

The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: sh: cpuinfo: Fix a warning for CONFIGCPUMASKOFFSTACK When CONFIGCPUMASKOFFSTACK and CONFIGDEBUGPERCPUMAPS are selected, cpumaxbitswarn generates a runtime warnin...

SUSE CVE-2022-49034

In the Linux kernel, the following vulnerability has been resolved: sh: cpuinfo: Fix a warning for CONFIGCPUMASKOFFSTACK When CONFIGCPUMASKOFFSTACK and CONFIGDEBUGPERCPUMAPS are selected, cpumaxbitswarn generates a runtime warning similar as below when showing /proc/cpuinfo. Fix this by using...

UBUNTU-CVE-2024-26945

In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - Fix nrcpus nriaa case If nrcpus nriaa, the calculated cpusperiaa will be 0, which causes a divide-by-0 in rebalancewqtable. Make sure cpusperiaa is 1 in that case, and also in the nriaa == 0 case, even though...

CVE-2023-52619

In the Linux kernel, the following vulnerability has been resolved: pstore/ram: Fix crash when setting number of cpus to an odd number When the number of cpu cores is adjusted to 7 or other odd numbers, the zone size will become an odd number. The address of the zone will become: addr of zone0 =...

CVE-2021-46910

In the Linux kernel, the following vulnerability has been resolved: ARM: 9063/1: mm: reduce maximum number of CPUs if DEBUGKMAPLOCAL is enabled The debugging code for kmaplocal doubles the number of per-CPU fixmap slots allocated for kmaplocal, in order to use half of them as guard regions. This...
