| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The
vmw translate ptr functions within the vmwgfx module of the Linux kernel incorrectly returned values after a code change related to pointer lookups. A previous implementation used a lookup function returning a pointer, which was then changed to a function returning an error code with the pointer as an out parameter. The error handling path was not updated to reflect this change, leading to the functions potentially returning success when they actually failed. This could result in uninitialized and out-of-bounds accesses.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
