Vulnerabilities > NULL Pointer Dereference
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-10-21 | CVE-2024-47743 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: KEYS: prevent NULL pointer dereference in find_asymmetric_key() In find_asymmetric_key(), if all NULLs are passed in the id_{0,1,2} arguments, the kernel will first emit WARN but then have an oops because id_2 gets dereferenced anyway. Add the missing id_2 check and move WARN_ON() to the final else branch to avoid duplicate NULL checks. Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool. | 5.5 |
| 2024-10-21 | CVE-2024-47749 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Added NULL check for lookup_atid The lookup_atid() function can return NULL if the ATID is invalid or does not exist in the identifier table, which could lead to dereferencing a null pointer without a check in the `act_establish()` and `act_open_rpl()` functions. Add a NULL check to prevent null pointer dereferencing. Found by Linux Verification Center (linuxtesting.org) with SVACE. | 5.5 |
| 2024-10-21 | CVE-2024-47752 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Fix H264 stateless decoder smatch warning Fix a smatch static checker warning on vdec_h264_req_if.c. Which leads to a kernel crash when fb is NULL. | 5.5 |
| 2024-10-21 | CVE-2024-47753 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Fix VP8 stateless decoder smatch warning Fix a smatch static checker warning on vdec_vp8_req_if.c. Which leads to a kernel crash when fb is NULL. | 5.5 |
| 2024-10-21 | CVE-2024-47754 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Fix H264 multi stateless decoder smatch warning Fix a smatch static checker warning on vdec_h264_req_multi_if.c. Which leads to a kernel crash when fb is NULL. | 5.5 |
| 2024-10-21 | CVE-2024-47756 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: PCI: keystone: Fix if-statement expression in ks_pcie_quirk() This code accidentally uses && where || was intended. | 5.5 |
| 2024-10-21 | CVE-2024-49850 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos In case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL referencing a non-existing BTF type, function bpf_core_calc_relo_insn would cause a null pointer deference. Fix this by adding a proper check upper in call stack, as malformed relocation records could be passed from user space. Simplest reproducer is a program: r0 = 0 exit With a single relocation record: .insn_off = 0, /* patch first instruction */ .type_id = 100500, /* this type id does not exist */ .access_str_off = 6, /* offset of string "0" */ .kind = BPF_CORE_TYPE_ID_LOCAL, See the link for original reproducer or next commit for a test case. | 5.5 |
| 2024-10-21 | CVE-2024-49857 | NULL Pointer Dereference vulnerability in Linux Kernel 6.11 In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: set the cipher for secured NDP ranging The cipher pointer is not set, but is derefereced trying to set its content, which leads to a NULL pointer dereference. Fix it by pointing to the cipher parameter before dereferencing. | 5.5 |
| 2024-10-21 | CVE-2024-47680 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: f2fs: check discard support for conventional zones As the helper function f2fs_bdev_support_discard() shows, f2fs checks if the target block devices support discard by calling bdev_max_discard_sectors() and bdev_is_zoned(). | 5.5 |
| 2024-10-21 | CVE-2024-47681 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: fix NULL pointer dereference in mt7996_mcu_sta_bfer_he Fix the NULL pointer dereference in mt7996_mcu_sta_bfer_he routine adding an sta interface to the mt7996 driver. Found by code review. | 5.5 |
