CVE-2023-52439

In the Linux kernel, the following vulnerability has been resolved: uio: Fix use-after-free in uio_open core-1 core-2 ------------------------------------------------------- uio_unregister_device uio_open idev = idr_find() device_unregister(&idev->dev) put_device(&idev->dev) uio_device_release get_device(&idev->dev) kfree(idev) uio_free_minor(minor) uio_release put_device(&idev->dev) kfree(idev) ------------------------------------------------------- In the core-1 uio_unregister_device(), the device_unregister will kfree idev when the idev->dev kobject ref is 1. But after core-1 device_unregister, put_device and before doing kfree, the core-2 may get_device. Then: 1. After core-1 kfree idev, the core-2 will do use-after-free for idev. 2. When core-2 do uio_release and put_device, the idev will be double freed. To address this issue, we can get idev atomic & inc idev reference with minor_lock.

To address this issue, we can get idev atomic & inc idev reference with minor_lock.(CVE-2023-52439)

A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues.(CVE-2024-1151)

NULL Pointer Dereference vulnerability in Linux Linux kernel kernel on Linux, x86, ARM (net, bluetooth modules) allows Overflow Buffers. This vulnerability is associated with program files /net/bluetooth/rfcomm/core.C.

This issue affects Linux kernel: v2.6.12-rc2.

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

f2fs: explicitly null-terminate the xattr list

When setting an xattr, explicitly null-terminate the xattr list. This eliminates the fragile assumption that the unused xattr space is always zeroed.(CVE-2023-52436)

In the Linux kernel, the following vulnerability has been resolved:

binder: fix use-after-free in shinker's callback

The mmap read lock is used during the shrinker's callback, which means that using alloc->vma pointer isn't safe as it can race with munmap(). As of commit dd2283f2605e ("mm: mmap: zap pages with read mmap_sem in munmap") the mmap lock is downgraded after the vma has been isolated.

I was able to reproduce this issue by manually adding some delays and triggering page reclaiming through the shrinker's debug sysfs. The following KASAN report confirms the UAF:

In btrfs_get_root_ref in fs/btrfs/disk-io.c in the Linux kernel through 6.7.1, there can be an assertion failure and crash because a subvolume can be read out too soon after its root item is inserted upon subvolume creation.(CVE-2024-23850)

In the Linux kernel, the following vulnerability has been resolved:

tls: fix race between async notify and socket close

The submitting thread (one which called recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete() so any code past that point risks touching already freed data.

Try to avoid the locking and extra flags altogether. Have the main thread hold an extra reference, this way we can depend solely on the atomic ref counter for synchronization.

Don't futz with reiniting the completion, either, we are now tightly controlling when completion fires.(CVE-2024-26583)

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:

• Block layer subsystem;
• Userspace I/O drivers;
• Ceph distributed file system;
• Ext4 file system;
• JFS file system;
• NILFS2 file system;
• Bluetooth subsystem;
• Networking core;
• IPv4 networking;
• IPv6 networking;
• Logical Link layer;
• MAC80211 subsystem;
• Netlink;
• NFC subsystem;
• Tomoyo security module; (CVE-2023-52524, CVE-2023-52530, CVE-2023-52601, CVE-2023-52439, CVE-2024-26635, CVE-2023-52602, CVE-2024-26614, CVE-2024-26704, CVE-2023-52604, CVE-2023-52566, CVE-2021-46981, CVE-2024-26622, CVE-2024-26735, CVE-2024-26805, CVE-2024-26801, CVE-2023-52583)
