CVE-2022-49267

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

media: davinci: vpif: fix use-after-free on driver unbind

The driver allocates and registers two platform device structures during probe, but the devices were never deregistered on driver unbind.

This results in a use-after-free on driver unbind as the device structures were allocated using devres and would be freed by driver core when remove() returns.

Fix this by adding the missing deregistration calls to the remove() callback and failing probe on registration errors.

Note that the platform device structures must be freed using a proper release callback to avoid leaking associated resources like device names.(CVE-2021-47653)

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

mmc: core: use sysfs_emit() instead of sprintf()

sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead.

Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.(CVE-2022-49267)

scsi: ufs: core: Fix handling of lrbp->cmd

ufshcd_queuecommand() may be called two times in a row for a SCSI command before it is completed. Hence make the following changes:

• In the functions that submit a command, do not check the old value of lrbp->cmd nor clear lrbp->cmd in error paths.

• In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.

See also scsi_send_eh_cmnd().

This commit prevents that the following appears if a command times out:

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

mmc: core: use sysfs_emit() instead of sprintf()

sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead.

Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
