| CVE-2024-43857 | 1 Linux | 1 Linux Kernel | 2024-12-09 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix null reference error when checking end of zone This patch fixes a potentially null pointer being accessed by is_end_zone_blkaddr() that checks the last block of a zone when f2fs is mounted as a single device. | |||||

| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe This commit addresses a null pointer dereference issue in the `dcn20_program_pipe` function. The issue could occur when `pipe_ctx->plane_state` is null. The fix adds a check to ensure `pipe_ctx->plane_state` is not null before accessing. This prevents a null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 dcn20_program_pipe() error: we previously assumed 'pipe_ctx->plane_state' could be null (see line 1877) | |||||

| In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix null pointer dereference in lpfc_prep_els_iocb() It is possible to call lpfc_issue_els_plogi() passing a did for which no matching ndlp is found. A call is then made to lpfc_prep_els_iocb() with a null pointer to a lpfc_nodelist structure resulting in a null pointer dereference. Fix by returning an error status if no valid ndlp is found. Fix up comments regarding ndlp reference counting. | |||||

| In the Linux kernel, the following vulnerability has been resolved: nvmet-rdma: Fix NULL deref when SEND is completed with error When running some traffic and taking down the link on peer, a retry counter exceeded error is received. This leads to nvmet_rdma_error_comp which tried accessing the cq_context to obtain the queue. The cq_context is no longer valid after the fix to use shared CQ mechanism and should be obtained similar to how it is obtained in other functions from the wc->qp.

This causes a null dereference error as the workqueue is only allocated and initialized in mcp251x_open(). To fix this we move the workqueue init to mcp251x_can_probe() as there is no reason to do it later and repeat it whenever mcp251x_open() is called. [mkl: fix error handling in mcp251x_stop()] | |||||

| The NASA’s Interplanetary Overlay Network (ION) is an implementation of Delay/Disruption Tolerant Networking (DTN). A segmentation fault occurs with ION-DTN BPv7 software version 4.1.3 when a bundle with a Destination Endpoint ID (EID) set to dtn:none is received. This causes the node to become unresponsive to incoming bundles, leading to a Denial of Service (DoS) condition. This vulnerability is fixed in 4.1.3s. | |||||

| A vulnerability, which was classified as problematic, was found in MSI Dragon Center up to 2.0.146.0. This affects the function MmUnMapIoSpace in the library NTIOLib_X64.sys of the component IOCTL Handler. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. Upgrading to version 2.0.148.0 is able to address this issue. It is recommended to upgrade the affected component. | |||||

| In the Linux kernel, the following vulnerability has been resolved: iio: light: veml6030: fix IIO device retrieval from embedded device The dev pointer that is received as an argument in the in_illuminance_period_available_show function references the device embedded in the IIO device, not in the i2c client. dev_to_iio_dev() must be used to accessthe right data. The current implementation leads to a segmentation fault on every attempt to read the attribute because indio_dev gets a NULL assignment. This bug has been present since the first appearance of the driver, apparently since the last version (V6) before getting applied. A constant attribute was used until then, and the last modifications might have not been tested again. | |||||

| In the Linux kernel, the following vulnerability has been resolved: idpf: fix idpf_vc_core_init error path In an event where the platform running the device control plane is rebooted, reset is detected on the driver. It releases all the resources and waits for the reset to complete. Once the reset is done, it tries to build the resources back. At this time if the device control plane is not yet started, then the driver timeouts on the virtchnl message and retries to establish the mailbox again. In the retry flow, mailbox is deinitialized but the mailbox workqueue is still alive and polling for the mailbox message. This results in accessing the released control queue leading to null-ptr-deref. Fix it by unrolling the work queue cancellation and mailbox deinitialization in the reverse order which they got initialized. | |||||

| In the Linux kernel, the following vulnerability has been resolved: hwmon: (hp-wmi-sensors) Check if WMI event data exists The BIOS can choose to return no event data in response to a WMI event, so the ACPI object passed to the WMI notify handler can be NULL. Check for such a situation and ignore the event in such a case. | |||||

| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Run DC_LOG_DC after checking link->link_enc [WHAT] The DC_LOG_DC should be run after link->link_enc is checked, not before. This fixes 1 REVERSE_INULL issue reported by Coverity. | |||||
| CVE-2024-46778 | 1 Linux | 1 Linux Kernel | 2024-11-20 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check UnboundedRequestEnabled's value CalculateSwathAndDETConfiguration_params_st's UnboundedRequestEnabled is a pointer (i.e. dml_bool_t *UnboundedRequestEnabled), and thus if (p->UnboundedRequestEnabled) checks its address, not bool value. This fixes 1 REVERSE_INULL issue reported by Coverity. | |||||
