Vulnerabilities > Divide By Zero
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-10-09 | CVE-2024-47664 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: spi: hisi-kunpeng: Add verification for the max_frequency provided by the firmware If the value of max_speed_hz is 0, it may cause a division by zero error in hisi_calc_effective_speed(). The value of max_speed_hz is provided by firmware. Firmware is generally considered as a trusted domain. | 5.5 |
| 2024-09-27 | CVE-2024-46806 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix the warning division or modulo by zero Checks the partition mode and returns an error for an invalid mode. | 5.5 |
| 2024-09-18 | CVE-2024-46772 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check denominator crb_pipes before used [WHAT & HOW] A denominator cannot be 0, and is checked before used. This fixes 2 DIVIDE_BY_ZERO issues reported by Coverity. | 5.5 |
| 2024-09-18 | CVE-2024-46773 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check denominator pbn_div before used [WHAT & HOW] A denominator cannot be 0, and is checked before used. This fixes 1 DIVIDE_BY_ZERO issue reported by Coverity. | 5.5 |
| 2024-09-18 | CVE-2024-46732 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Assign linear_pitch_alignment even for VM [Description] Assign linear_pitch_alignment so we don't cause a divide by 0 error in VM environments | 5.5 |
| 2024-09-13 | CVE-2024-6135 | Divide By Zero vulnerability in Zephyrproject Zephyr BT:Classic: Multiple missing buf length checks | 6.5 |
| 2024-09-13 | CVE-2024-46676 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: Add poll mod list filling check In case of im_protocols value is 1 and tm_protocols value is 0 this combination successfully passes the check 'if (!im_protocols && !tm_protocols)' in the nfc_start_poll(). But then after pn533_poll_create_mod_list() call in pn533_start_poll() poll mod list will remain empty and dev->poll_mod_count will remain 0 which lead to division by zero. Normally no im protocol has value 1 in the mask, so this combination is not expected by driver. | 5.5 |

| 2024-08-26 | CVE-2024-43893 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: serial: core: check uartclk for zero to avoid divide by zero Calling ioctl TIOCSSERIAL with an invalid baud_base can result in uartclk being zero, which will result in a divide by zero error in uart_get_divisor(). | 5.5 |
| 2024-08-17 | CVE-2024-42316 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/mglru: fix div-by-zero in vmpressure_calc_level() evict_folios() uses a second pass to reclaim folios that have gone through page writeback and become clean before it finishes the first pass, since folio_rotate_reclaimable() cannot handle those folios due to the isolation. The second pass tries to avoid potential double counting by deducting scan_control->nr_scanned. | 5.5 |
