CVE-2023-53500

In the Linux kernel, the following vulnerability has been resolved: xfrm: fix slab-use-after-free in decode_session6 When the xfrm device is set to the qdisc of the sfb type, the cb field of the sent skb may be modified during enqueuing. Then, slab-use-after-free may occur when the xfrm device sends IPv6 packets.

Security Fix(es):

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

misc: tifm: fix possible memory leak in tifm_7xx1_switch_media()

If device_register() returns error in tifm_7xx1_switch_media(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked.

Never directly free @dev after calling device_register(), even if it returned an error! Always use put_device() to give up the reference initialized.(CVE-2022-50349)

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

net: hns: fix possible memory leak in hnae_ae_register()

Inject fault while probing module, if device_register() fails, but the refcount of kobject is not decreased to 0, the name allocated in dev_set_name() is leaked. Fix this by calling put_device(), so that name can be freed in callback function kobject_cleanup().

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

ext4: avoid crash when inline data creation follows DIO write

When inode is created and written to using direct IO, there is nothing to clear the EXT4_STATE_MAY_INLINE_DATA flag. Thus when inode gets truncated later to say 1 byte and written using normal write, we will try to store the data as inline data. This confuses the code later because the inode now has both normal block and inline data allocated and the confusion manifests for example as:
