CWE-476

In the Linux kernel, the following vulnerability has been resolved: null_blk: Always check queue mode setting from configfs Make sure to check device queue mode in the null_validate_conf() and return error for NULL_Q_RQ as we don't allow legacy I/O path, without this patch we…

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: Check for probe() id argument being NULL The probe() id argument may be NULL in 2 scenarios: 1. brcmf_pcie_pm_leave_D3() calling brcmf_pcie_probe() to reprobe the device. 2. If a user…

In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix NULL pointer dereference when removing device In suspend and resume cycle, the removal and rescan of device ends up in NULL pointer dereference. During driver initialization, if the…

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: u_serial: Add null pointer check in gserial_resume Consider a case where gserial_disconnect has already cleared gser->ioport. And if a wakeup interrupt triggers afterwards, gserial_resume gets…

In the Linux kernel, the following vulnerability has been resolved: btrfs: insert tree mod log move in push_node_left There is a fairly unlikely race condition in tree mod log rewind that can result in a kernel panic which has the following trace: [530.569] BTRFS critical…

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: mtk_drm_crtc: Add checks for devm_kcalloc As the devm_kcalloc may return NULL, the return value needs to be checked to avoid NULL poineter dereference.

In the Linux kernel, the following vulnerability has been resolved: drbd: only clone bio if we have a backing device Commit c347a787e34cb (drbd: set ->bi_bdev in drbd_req_new) moved a bio_set_dev call (which has since been removed) to "earlier", from drbd_request_prepare to…

In the Linux kernel, the following vulnerability has been resolved: mtd: lpddr2_nvm: Fix possible null-ptr-deref It will cause null-ptr-deref when resource_size(add_range) invoked, if platform_get_resource() returns NULL.

In the Linux kernel, the following vulnerability has been resolved: media: coda: Add check for dcoda_iram_alloc As the coda_iram_alloc may return NULL pointer, it should be better to check the return value in order to avoid NULL poineter dereference, same as the others.

In the Linux kernel, the following vulnerability has been resolved: cxl: fix possible null-ptr-deref in cxl_guest_init_afu|adapter() If device_register() fails in cxl_register_afu|adapter(), the device is not added, device_unregister() can not be called in the error path,…

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Make sure "ib_port" is valid when access sysfs node The "ib_port" structure must be set before adding the sysfs kobject, and reset after removing it, otherwise it may crash when accessing the sysfs…

In the Linux kernel, the following vulnerability has been resolved: net/tcp: Fix a NULL pointer dereference when using TCP-AO with TCP_REPAIR A NULL pointer dereference can occur in tcp_ao_finish_connect() during a connect() system call on a socket with a TCP-AO key added and…

In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: q6apm-lpass-dais: Fix NULL pointer dereference if source graph failed If earlier opening of source graph fails (e.g. ADSP rejects due to incorrect audioreach topology), the graph is closed and…

In the Linux kernel, the following vulnerability has been resolved: net: rfkill: gpio: Fix crash due to dereferencering uninitialized pointer Since commit 7d5e9737efda ("net: rfkill: gpio: get the name and type from device property") rfkill_find_type() gets called with the…

In the Linux kernel, the following vulnerability has been resolved: drm: bridge: anx7625: Fix NULL pointer dereference with early IRQ If the interrupt occurs before resource initialization is complete, the interrupt handler/worker may access uninitialized data such as the I2C…

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential null dereference The adev->dm.dc pointer can be NULL and dereferenced in amdgpu_dm_fini() without checking. Add a NULL pointer check before calling dc_dmub_srv_destroy(). Found…

In the Linux kernel, the following vulnerability has been resolved: media: vsp1: Replace vb2_is_streaming() with vb2_start_streaming_called() The vsp1 driver uses the vb2_is_streaming() function in its .buf_queue() handler to check if the .start_streaming() operation has been…

In the Linux kernel, the following vulnerability has been resolved: ACPI: processor: Check for null return of devm_kzalloc() in fch_misc_setup() devm_kzalloc() may fail, clk_data->name might be NULL and will cause a NULL pointer dereference later. [ rjw: Subject and changelog…

In the Linux kernel, the following vulnerability has been resolved: kobject: Add sanity check for kset->kobj.ktype in kset_register() When I register a kset in the following way: static struct kset my_kset; kobject_set_name(&my_kset.kobj, "my_kset"); ret =…

In the Linux kernel, the following vulnerability has been resolved: iw_cxgb4: Fix potential NULL dereference in c4iw_fill_res_cm_id_entry() This condition needs to match the previous "if (epcp->state == LISTEN) {" exactly to avoid a NULL dereference of either "listen_ep" or…
