| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-10-21 | CVE-2024-49891 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Validate hdwq pointers before dereferencing in reset/errata paths When the HBA is undergoing a reset or is handling an errata event, NULL ptr dereference crashes may occur in routines such as lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or lpfc_abort_handler(). Add NULL ptr checks before dereferencing hdwq pointers that may have been freed due to operations colliding with a reset or errata event handler. | 5.5 |
| 2024-10-21 | CVE-2024-49892 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize get_bytes_per_element's default to 1 Variables, used as denominators and maybe not assigned to other values, should not be 0. | 5.5 |
| 2024-10-21 | CVE-2024-49893 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check stream_status before it is used [WHAT & HOW] dc_state_get_stream_status can return null, and therefore null must be checked before stream_status is used. This fixes 1 NULL_RETURNS issue reported by Coverity. | 5.5 |
| 2024-10-21 | CVE-2024-49894 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix index out of bounds in degamma hardware format translation Fixes index out of bounds issue in `cm_helper_translate_curve_to_degamma_hw_format` function. | 7.8 |
| 2024-10-21 | CVE-2024-49895 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation This commit addresses a potential index out of bounds issue in the `cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30 color management module. | 7.8 |
| 2024-10-21 | CVE-2024-49896 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check stream before comparing them [WHAT & HOW] amdgpu_dm can pass a null stream to dc_is_stream_unchanged. | 5.5 |
| 2024-10-21 | CVE-2024-49897 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check phantom_stream before it is used dcn32_enable_phantom_stream can return null, so returned value must be checked before used. This fixes 1 NULL_RETURNS issue reported by Coverity. | 5.5 |
| 2024-10-21 | CVE-2024-49898 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null-initialized variables [WHAT & HOW] drr_timing and subvp_pipe are initialized to null and they are not always assigned new values. | 5.5 |
| 2024-10-21 | CVE-2024-49899 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize denominators' default to 1 [WHAT & HOW] Variables used as denominators and maybe not assigned to other values, should not be 0. | 5.5 |
| 2024-10-21 | CVE-2024-49900 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: jfs: Fix uninit-value access of new_ea in ea_buffer syzbot reports that lzo1x_1_do_compress is using uninit-value: ===================================================== BUG: KMSAN: uninit-value in lzo1x_1_do_compress+0x19f9/0x2510 lib/lzo/lzo1x_compress.c:178 ... Uninit was stored to memory at: ea_put fs/jfs/xattr.c:639 [inline] ... Local variable ea_buf created at: __jfs_setxattr+0x5d/0x1ae0 fs/jfs/xattr.c:662 __jfs_xattr_set+0xe6/0x1f0 fs/jfs/xattr.c:934 ===================================================== The reason is ea_buf->new_ea is not initialized properly. Fix this by using memset to empty its content at the beginning in ea_get(). | 7.1 |
