| CVE-2025-68820 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ext4: xattr: fix null pointer deref in ext4_raw_inode() If ext4_get_inode_loc() fails (e.g. if it returns -EFSCORRUPTED), iloc.bh will remain set to NULL. Since ext4_xattr_inode_dec_ref_all() lacks error checking, this will lead to a null pointer dereference in ext4_raw_inode(), called right after ext4_get_inode_loc().

| In the Linux kernel, the following vulnerability has been resolved: spi: fsl-cpm: Check length parity before switching to 16 bit mode Commit fc96ec826bce ("spi: fsl-cpm: Use 16 bit mode for large transfers with even size") failed to make sure that the size is really even before switching to 16 bit mode. Until recently the problem went unnoticed because kernfs uses a pre-allocated bounce buffer of size PAGE_SIZE for reading EEPROM. But commit 8ad6249c51d0 ("eeprom: at25: convert to spi-mem API") introduced an additional dynamically allocated bounce buffer whose size is exactly the size of the transfer, leading to a buffer overrun in the fsl-cpm driver when that size is odd. Add the missing length parity verification and remain in 8 bit mode when the length is not even. | ||||
| CVE-2025-68378 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix stackmap overflow check in __bpf_get_stackid() Syzkaller reported a KASAN slab-out-of-bounds write in __bpf_get_stackid() when copying stack trace data. The issue occurs when the perf trace contains more stack entries than the stack map bucket can hold, leading to an out-of-bounds write in the bucket's data array. | ||||
| CVE-2025-68376 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: coresight: ETR: Fix ETR buffer use-after-free issue When ETR is enabled as CS_MODE_SYSFS, if the buffer size is changed and enabled again, currently sysfs_buf will point to the newly allocated memory(buf_new) and free the old memory(buf_old). But the etr_buf that is being used by the ETR remains pointed to buf_old, not updated to buf_new. In this case, it will result in a memory use-after-free issue. Fix this by checking ETR's mode before updating and releasing buf_old, if the mode is CS_MODE_SYSFS, then skip updating and releasing it. | ||||
| CVE-2025-68369 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ntfs3: init run lock for extend inode After setting the inode mode of $Extend to a regular file, executing the truncate system call will enter the do_truncate() routine, causing the run_lock uninitialized error reported by syzbot. Prior to patch 4e8011ffec79, if the inode mode of $Extend was not set to a regular file, the do_truncate() routine would not be entered. Add the run_lock initialization when loading $Extend. syzbot reported: INFO: trying to register non-static key.

| CVE-2025-68312 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: usbnet: Prevents free active kevent The root cause of this issue are: 1. When probing the usbnet device, executing usbnet_link_change(dev, 0, 0); put the kevent work in global workqueue. However, the kevent has not yet been scheduled when the usbnet device is unregistered. Therefore, executing free_netdev() results in the "free active object (kevent)" error reported here. 2. Another factor is that when calling usbnet_disconnect()->unregister_netdev(), if the usbnet device is up, ndo_stop() is executed to cancel the kevent. However, because the device is not up, ndo_stop() is not executed. The solution to this problem is to cancel the kevent before executing free_netdev(). | ||||

To prevent this the code now tries to iterate over the list backwards to ensure the links are cleanup before its parents, also it no longer relies on a cursor, instead it always uses the last element since hci_abort_conn_sync is guaranteed to call hci_conn_del.

| In the Linux kernel, the following vulnerability has been resolved: net: deal with integer overflows in kmalloc_reserve() Blamed commit changed: ptr = kmalloc(size); if (ptr) size = ksize(ptr); size = kmalloc_size_roundup(size); ptr = kmalloc(size); This allowed various crash as reported by syzbot [1] and Kyle Zeng. Problem is that if @size is bigger than 0x80000001, kmalloc_size_roundup(size) returns 2^32. kmalloc_reserve() uses a 32bit variable (obj_size), so 2^32 is truncated to 0. kmalloc(0) returns ZERO_SIZE_PTR which is not handled by skb allocations. Following trace can be triggered if a netdev->mtu is set close to 0x7fffffff We might in the future limit netdev->mtu to more sensible limit (like KMALLOC_MAX_SIZE). This patch is based on a syzbot report, and also a report and tentative fix from Kyle Zeng.

| In the Linux kernel, the following vulnerability has been resolved: caif: fix integer underflow in cffrml_receive() The cffrml_receive() function extracts a length field from the packet header and, when FCS is disabled, subtracts 2 from this length without validating that len >= 2. If an attacker sends a malicious packet with a length field of 0 or 1 to an interface with FCS disabled, the subtraction causes an integer underflow. This can lead to memory exhaustion and kernel instability, potential information disclosure if padding contains uninitialized kernel memory. Fix this by validating that len >= 2 before performing the subtraction. | ||||

| In the Linux kernel, the following vulnerability has been resolved: udf: Detect system inodes linked into directory hierarchy When UDF filesystem is corrupted, hidden system inodes can be linked into directory hierarchy which is an avenue for further serious corruption of the filesystem and kernel confusion as noticed by syzbot fuzzed images. Refuse to access system inodes linked into directory hierarchy and vice versa. | ||||
