CVE-2023-52458 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Eus 2026-01-05 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: block: add check that partition length needs to be aligned with block size Before calling add partition or resize partition, there is no check on whether the length is aligned with the logical block size. If the logical block size of the disk is larger than 512 bytes, then the partition size maybe not the multiple of the logical block size, and when the last sector is read, bio_truncate() will adjust the bio size, resulting in an IO error if the size of the read command is smaller than the logical block size.If integrity data is supported, this will also result in a null pointer dereference when calling bio_integrity_free.

CVE-2025-38705 1 Linux 1 Linux Kernel 2026-01-02 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix null pointer access Writing a string without delimiters (' ', '\n', '\0') to the under gpu_od/fan_ctrl sysfs or pp_power_profile_mode for the CUSTOM profile will result in a null pointer dereference.
CVE-2025-38269 1 Linux 1 Linux Kernel 2026-01-02 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: btrfs: exit after state insertion failure at btrfs_convert_extent_bit() If insert_state() state failed it returns an error pointer and we call extent_io_tree_panic() which will trigger a BUG() call. However if CONFIG_BUG is disabled, which is an uncommon and exotic scenario, then we fallthrough and call cache_state() which will dereference the error pointer, resulting in an invalid memory access. So jump to the 'out' label after calling extent_io_tree_panic(), it also makes the code more clear besides dealing with the exotic scenario where CONFIG_BUG is disabled.
CVE-2025-38208 1 Linux 1 Linux Kernel 2026-01-02 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: smb: client: add NULL check in automount_fullpath page is checked for null in __build_path_from_dentry_optional_prefix when tcon->origin_fullpath is not set. However, the check is missing when it is set. Add a check to prevent a potential NULL pointer dereference.
CVE-2025-38034 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-01-02 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: btrfs: correct the order of prelim_ref arguments in btrfs__prelim_ref btrfs_prelim_ref() calls the old and new reference variables in the incorrect order. This causes a NULL pointer dereference because oldref is passed as NULL to trace_btrfs_prelim_ref_insert(). Note, trace_btrfs_prelim_ref_insert() is being called with newref as oldref (and oldref as NULL) on purpose in order to print out the values of newref. To reproduce: echo 1 > /sys/kernel/debug/tracing/events/btrfs/btrfs_prelim_ref_insert/enable Perform some writeback operations.

In the Linux kernel, the following vulnerability has been resolved: HID: pidff: Fix null pointer dereference in pidff_find_fields This function triggered a null pointer dereference if used to search for a report that isn't implemented on the device. This happened both for optional and required reports alike. The same logic was applied to pidff_find_special_field and although pidff_init_fields should return an error earlier if one of the required reports is missing, future modifications could change this logic and resurface this possible null pointer dereference again.

CVE-2025-37800 1 Linux 1 Linux Kernel 2026-01-02 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: driver core: fix potential NULL pointer dereference in dev_uevent() If userspace reads "uevent" device attribute at the same time as another threads unbinds the device from its driver, change to dev->driver from a valid pointer to NULL may result in crash. Fix this by using READ_ONCE() when fetching the pointer, and take bus' drivers klist lock to make sure driver instance will not disappear while we access it. Use WRITE_ONCE() when setting the driver pointer to ensure there is no tearing.

CVE-2025-21744 1 Linux 1 Linux Kernel 2026-01-02 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: fix NULL pointer dereference in brcmf_txfinalize() On removal of the device or unloading of the kernel module a potential NULL pointer dereference occurs. The following sequence deletes the interface: brcmf_detach() brcmf_remove_interface() brcmf_del_if() Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches. After brcmf_remove_interface() call the brcmf_proto_detach() function is called providing the following sequence: brcmf_detach() brcmf_proto_detach() brcmf_proto_msgbuf_detach() brcmf_flowring_detach() brcmf_msgbuf_delete_flowring() brcmf_msgbuf_remove_flowring() brcmf_flowring_delete() brcmf_get_ifp() brcmf_txfinalize() Since brcmf_get_ip() can and actually will return NULL in this case the call to brcmf_txfinalize() will result in a NULL pointer dereference inside brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors. This will only happen if a flowring still has an skb. Although the NULL pointer dereference has only been seen when trying to update the tx statistic, all other uses of the ifp pointer have been guarded as well with an early return if ifp is NULL.
CVE-2025-14957 1 Webassembly 1 Binaryen 2025-12-30 3.3 Low
A vulnerability was identified in WebAssembly Binaryen up to 125. This affects the function IRBuilder::makeLocalGet/IRBuilder::makeLocalSet/IRBuilder::makeLocalTee of the file src/wasm/wasm-ir-builder.cpp of the component IRBuilder. Such manipulation of the argument Index leads to null pointer dereference. Local access is required to approach this attack. The exploit is publicly available and might be used. The name of the patch is 6fb2b917a79578ab44cf3b900a6da4c27251e0d4. Applying a patch is advised to resolve this issue.
CVE-2025-15156 1 Omec-project 1 Upf 2025-12-29 4.3 Medium
A flaw has been found in omec-project UPF up to 2.1.3-dev. This affects the function handleSessionEstablishmentRequest of the file /pfcpiface/pfcpiface/messages_session.go of the component PFCP Session Establishment Request Handler. This manipulation causes null pointer dereference. The attack may be initiated remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
