| 2025-04-16 | CVE-2025-22066 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: imx-card: Add NULL check in imx_card_probe() devm_kasprintf() returns NULL when memory allocation fails. | 5.5 |
| 2025-04-16 | CVE-2025-22070 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: fs/9p: fix NULL pointer dereference on mkdir When a 9p tree was mounted with option 'posixacl', parent directory had a default ACL set for its subdirectories, e.g.: setfacl -m default:group:simpsons:rwx parentdir then creating a subdirectory crashed 9p client, as v9fs_fid_add() call in function v9fs_vfs_mkdir_dotl() sets the passed 'fid' pointer to NULL (since dafbe689736) even though the subsequent v9fs_set_create_acl() call expects a valid non-NULL 'fid' pointer: [ 37.273191] BUG: kernel NULL pointer dereference, address: 0000000000000000 ...

| 2025-04-16 | CVE-2025-23136 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: thermal: int340x: Add NULL check for adev Not all devices have an ACPI companion fwnode, so adev might be NULL. This is similar to the commit cd2fd6eab480 ("platform/x86: int3472: Check for adev == NULL"). Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in int3402_thermal_probe(). Note, under the same directory, int3400_thermal_probe() has such a check. [ rjw: Subject edit, added Fixes: ] | 5.5 |
| 2025-04-16 | CVE-2025-23137 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cpufreq/amd-pstate: Add missing NULL ptr check in amd_pstate_update Check if policy is NULL before dereferencing it in amd_pstate_update. | 5.5 |
| 2025-04-16 | CVE-2025-22027 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: streamzap: fix race between device disconnection and urb callback Syzkaller has reported a general protection fault at function ir_raw_event_store_with_filter(). | 4.7 |
| 2025-04-16 | CVE-2025-22031 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: PCI/bwctrl: Fix NULL pointer dereference on bus number exhaustion When BIOS neglects to assign bus numbers to PCI bridges, the kernel attempts to correct that during PCI device enumeration. | 5.5 |
| 2025-04-16 | CVE-2025-22032 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix kernel panic due to null pointer dereference Address a kernel panic caused by a null pointer dereference in the `mt792x_rx_get_wcid` function. | 5.5 |

| 2025-04-16 | CVE-2025-22037 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference in alloc_preauth_hash() The Client send malformed smb2 negotiate request. | 5.5 |
| 2025-04-16 | CVE-2025-22051 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: staging: gpib: Fix Oops after disconnect in agilent usb If the agilent usb dongle is disconnected subsequent calls to the driver cause a NULL dereference Oops as the bus_interface is set to NULL on disconnect. This problem was introduced by setting usb_dev from the bus_interface for dev_xxx messages. Previously bus_interface was checked for NULL only in the functions directly calling usb_fill_bulk_urb or usb_control_msg. Check for valid bus_interface on all interface entry points and return -ENODEV if it is NULL. | 5.5 |
