CVE-2022-49448

In the Linux kernel, the following vulnerability has been resolved: soc: bcm: Check for NULL return of devmkzalloc As the potential failure of allocation, devmkzalloc may return NULL. Then the 'pd-pmb' and the follow lines of code may bring null pointer dereference. Therefore, it is better to che...

CVE-2022-49417

CVE-2022-49417 involves the Linux kernel component iwlwifi/mei. The issue is a potential NULL-ptr dereference that could occur when SKB allocation fails; the fix was to skip using the NULL pointer instead of dereferencing it. This vulnerability is described as resolved in multiple sources and is ...

CVE-2022-49334 mm/huge_memory: Fix xarray node memory leak

In the Linux kernel, the following vulnerability has been resolved: mm/hugememory: Fix xarray node memory leak If xassplitalloc fails to allocate the necessary nodes to complete the xarray entry split, it sets the xastate to -ENOMEM, which xasnomem then interprets as "Please allocate more memory"...

CVE-2022-49268

Summary: CVE-2022-49268 affects the Linux kernel ASoC: SOF Intel path and causes a NULL pointer dereference when ENOMEM occurs during noncontiguous DMA allocations. The issue arises if snd_dma_free_pages() is called after snd_dma_alloc_pages() returns -ENOMEM, leading to a NULL dereference in dma...

CVE-2022-49184 net: sparx5: switchdev: fix possible NULL pointer dereference

In the Linux kernel, the following vulnerability has been resolved: net: sparx5: switchdev: fix possible NULL pointer dereference As the possible failure of the allocation, devmkzalloc may return NULL pointer. Therefore, it should be better to check the 'db' in order to prevent the dereference of...

CVE-2021-47651

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: rpmpd: Check for null return of devmkcalloc Because of the possible failure of the allocation, data-domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better ...
