CVE-2022-49285 1 Linux 1 Linux Kernel 2025-09-22 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iio: accel: mma8452: use the correct logic to get mma8452_data The original logic to get mma8452_data is wrong, the *dev point to the device belong to iio_dev. we can't use this dev to find the correct i2c_client. The original logic happen to work because it finally use dev->driver_data to get iio_dev. Here use the API to_i2c_client() is wrong and make reader confuse. To correct the logic, it should be like this struct mma8452_data *data = iio_priv(dev_get_drvdata(dev)); But after commit 8b7651f25962 ("iio: iio_device_alloc(): Remove unnecessary self drvdata"), the upper logic also can't work. When try to show the avialable scale in userspace, will meet kernel dump, kernel handle NULL pointer dereference. So use dev_to_iio_dev() to correct the logic. Dual fixes tags as the second reflects when the bug was exposed, whilst the first reflects when the original bug was introduced.
CVE-2022-49268 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-22 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM Do not call snd_dma_free_pages() when snd_dma_alloc_pages() returns -ENOMEM because it leads to a NULL pointer dereference bug.

CVE-2022-49417 1 Linux 1 Linux Kernel 2025-09-22 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iwlwifi: mei: fix potential NULL-ptr deref If SKB allocation fails, continue rather than using the NULL pointer. Coverity CID: 1497650
CVE-2022-49286 1 Linux 1 Linux Kernel 2025-09-22 4.7 Medium
In the Linux kernel, the following vulnerability has been resolved: tpm: use try_get_ops() in tpm-space.c As part of the series conversion to remove nested TPM operations: https://lore.kernel.org/all/20190205224723.19671-1-jarkko.sakkinen@linux.intel.com/ exposure of the chip->tpm_mutex was removed from much of the upper level code. In this conversion, tpm2_del_space() was missed. This didn't matter much because it's usually called closely after a converted operation, so there's only a very tiny race window where the chip can be removed before the space flushing is done which causes a NULL deref on the mutex. However, there are reports of this window being hit in practice, so fix this by converting tpm2_del_space() to use tpm_try_get_ops(), which performs all the teardown checks before acquring the mutex.

CVE-2024-35842 1 Linux 1 Linux Kernel 2025-09-19 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: sof-common: Add NULL check for normal_link string It's not granted that all entries of struct sof_conn_stream declare a `normal_link` (a non-SOF, direct link) string, and this is the case for SoCs that support only SOF paths (hence do not support both direct and SOF usecases). For example, in the case of MT8188 there is no normal_link string in any of the sof_conn_stream entries and there will be more drivers doing that in the future. To avoid possible NULL pointer KPs, add a NULL check for `normal_link`.

CVE-2025-22037 1 Linux 1 Linux Kernel 2025-09-19 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference in alloc_preauth_hash() The Client send malformed smb2 negotiate request. ksmbd return error response.
