Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s videobuf2 subsystem. The
vb2 ioctl remove bufs() function can manipulate the internal buffer list of a queue, potentially overwriting pointers used when legacy fileio access mode is active. This occurs when the ioctl is called while fileio is active, which can compromise the internal queue state during subsequent read or write operations.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
