| CVE-2024-36831 | 1 Dlink | 2 Dap-1520, Dap-1520 Firmware | 2025-05-21 | 5.3 Medium |
| A NULL pointer dereference in the plugins_call_handle_uri_clean function of D-Link DAP-1520 REVA_FIRMWARE_1.10B04_BETA02_HOTFIX allows attackers to cause a Denial of Service (DoS) via a crafted HTTP request without authentication. | ||||
| CVE-2025-32912 | 1 Redhat | 1 Enterprise Linux | 2025-05-21 | 6.5 Medium |
| A flaw was found in libsoup, where SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP server may cause the libsoup client to crash. | ||||
| CVE-2024-36832 | 1 Dlink | 2 Dap-1513, Dap-1513 Firmware | 2025-05-21 | 7.5 High |
| A NULL pointer dereference in D-Link DAP-1513 REVA_FIRMWARE_1.01 allows attackers to cause a Denial of Service (DoS) via a crafted web request without authentication. The vulnerability occurs in the /bin/webs binary of the firmware. When /bin/webs receives a carefully constructed HTTP request, it will crash and exit due to a null pointer reference, leading to a denial of service attack to the device. | ||||
| CVE-2024-33345 | 2 D-link, Dlink | 3 Dir-823g, Dir-823g, Dir-823g Firmware | 2025-05-21 | 6.5 Medium |
| D-Link DIR-823G A1V1.0.2B05 was found to contain a Null-pointer dereference in the main function of upload_firmware.cgi, which allows remote attackers to cause a Denial of Service (DoS) via a crafted input. | ||||
| CVE-2024-50049 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null pointer before dereferencing se [WHAT & HOW] se is null checked previously in the same function, indicating it might be null; therefore, it must be checked when used again. This fixes 1 FORWARD_NULL issue reported by Coverity. | ||||
| CVE-2024-50048 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: fbcon: Fix a NULL pointer dereference issue in fbcon_putcs syzbot has found a NULL pointer dereference bug in fbcon. Here is the simplified C reproducer: struct param { uint8_t type; struct tiocl_selection ts; }; int main() { struct fb_con2fbmap con2fb; struct param param; int fd = open("/dev/fb1", 0, 0); con2fb.console = 0x19; con2fb.framebuffer = 0; ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb); param.type = 2; param.ts.xs = 0; param.ts.ys = 0; param.ts.xe = 0; param.ts.ye = 0; param.ts.sel_mode = 0; int fd1 = open("/dev/tty1", O_RDWR, 0); ioctl(fd1, TIOCLINUX, ¶m); con2fb.console = 1; con2fb.framebuffer = 0; ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb); return 0; } After calling ioctl(fd1, TIOCLINUX, ¶m), the subsequent ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb) causes the kernel to follow a different execution path: set_con2fb_map -> con2fb_init_display -> fbcon_set_disp -> redraw_screen -> hide_cursor -> clear_selection -> highlight -> invert_screen -> do_update_region -> fbcon_putcs -> ops->putcs Since ops->putcs is a NULL pointer, this leads to a kernel panic. To prevent this, we need to call set_blitting_type() within set_con2fb_map() to properly initialize ops->putcs. | ||||
| CVE-2024-49987 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpftool: Fix undefined behavior in qsort(NULL, 0, ...) When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). This results in undefined behavior, as UBSan reports: net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions: "Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined." To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer. | ||||
| CVE-2024-49962 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ACPICA: check null return of ACPI_ALLOCATE_ZEROED() in acpi_db_convert_to_package() ACPICA commit 4d4547cf13cca820ff7e0f859ba83e1a610b9fd0 ACPI_ALLOCATE_ZEROED() may fail, elements might be NULL and will cause NULL pointer dereference later.

| CVE-2024-49929 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: avoid NULL pointer dereference iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta pointer is not NULL. It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is dereferencing the ieee80211_sta pointer. If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL pointer. Fix this by checking the sta pointer before retrieving the mvmsta from it. If sta is not NULL, then mvmsta isn't either. | ||||
| CVE-2024-49909 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn32_set_output_transfer_func function. Previously, set_output_gamma was being checked for null, but then it was being dereferenced without any null check. This could lead to a null pointer dereference if set_output_gamma is null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a null check for set_output_gamma before the call to set_output_gamma. | ||||
| CVE-2024-49896 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| 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. It is necessary to check for null before dereferencing them. This fixes 1 FORWARD_NULL issue reported by Coverity. | ||||
| CVE-2024-49890 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: ensure the fw_info is not null before using it This resolves the dereference null return value warning reported by Coverity. | ||||
| CVE-2024-46807 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-21 | 5.5 Medium |

| CVE-2024-46803 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check debug trap enable before write dbg_ev_file In interrupt context, write dbg_ev_file will be run by work queue. It will cause write dbg_ev_file execution after debug_trap_disable, which will cause NULL pointer access. v2: cancel work "debug_event_workarea" before set dbg_ev_file as NULL. | ||||
| CVE-2024-43909 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/pm: Fix the null pointer dereference for smu7 optimize the code to avoid pass a null pointer (hwmgr->backend) to function smu7_update_edc_leakage_table. | ||||

| CVE-2024-42224 | 1 Linux | 1 Linux Kernel | 2025-05-21 | 6.1 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: Correct check for empty list Since commit a3c53be55c95 ("net: dsa: mv88e6xxx: Support multiple MDIO busses") mv88e6xxx_default_mdio_bus() has checked that the return value of list_first_entry() is non-NULL. This appears to be intended to guard against the list chip->mdios being empty. However, it is not the correct check as the implementation of list_first_entry is not designed to return NULL for empty lists. Instead, use list_first_entry_or_null() which does return NULL if the list is empty. Flagged by Smatch. Compile tested only. | ||||
