CVE-2023-53711

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix a potential data corruption We must ensure that the subrequests are joined back into the head before we can retransmit a request. If the head was not on the commit lists, because the server wrote it synchronously, we still need to add it back to the retransmission list. Add a call that mirrors the effect of nfs_cancel_remove_inode() for O_DIRECT.

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

ext4: fix potential out of bound read in ext4_fc_replay_scan()

For scan loop must ensure that at least EXT4_FC_TAG_BASE_LEN space. If remain space less than EXT4_FC_TAG_BASE_LEN which will lead to out of bound read when mounting corrupt file system image. ADD_RANGE/HEAD/TAIL is needed to add extra check when do journal scan, as this three tags will read data during scan, tag length couldn't less than data length which will read.(CVE-2022-50306)

A use-after-free vulnerability in the Linux kernel s netfilter: nf_tables component can be exploited to achieve local privilege escalation.Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8.(CVE-2023-4244)

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

HID: multitouch: Correct devm device reference for hidinput input_dev name

Reference the HID device rather than the input device for the devm allocation of the input_dev name. Referencing the input_dev would lead to a use-after-free when the input_dev was unregistered and subsequently fires a uevent that depends on the name. At the point of firing the uevent, the name would be freed by devres management.

Use devm_kasprintf to simplify the logic for allocating memory and formatting the input_dev name string.(CVE-2023-53454)

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

scsi: qla2xxx: Fix deletion race condition

System crash when using debug kernel due to link list corruption. The cause of the link list corruption is due to session deletion was allowed to queue up twice. Here's the internal trace that show the same port was allowed to double queue for deletion on different cpu.

Move the clearing/setting of deleted flag lock.(CVE-2023-53615)

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

scsi: ses: Fix possible desc_ptr out-of-bounds accesses

Sanitize possible desc_ptr out-of-bounds accesses in ses_enclosure_data_process().(CVE-2023-53675)

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

NFS: Fix a potential data corruption

We must ensure that the subrequests are joined back into the head before we can retransmit a request. If the head was not on the commit lists, because the server wrote it synchronously, we still need to add it back to the retransmission list. Add a call that mirrors the effect of nfs_cancel_remove_inode() for O_DIRECT.(CVE-2023-53711)

In the Linux kernel, the following vulnerability has been resolved: md: raid1: fix potential OOB in raid1_remove_disk(). If rddev->raid_disk is greater than mddev->raid_disks, there will be an out-of-bounds in raid1_remove_disk(). We have already found similar reports as follows: 1) commit d17f744e883b ("md-raid10: fix KASAN warning") 2) commit 1ebc2cec0b7d ("dm raid: fix KASAN warning in raid5_remove_disk"). Fix this bug by checking whether the "number" variable is valid.(CVE-2023-53722)
