Description Rohit Keshri 2023-05-15 11:36:02 UTC

Improper restriction of operations within the bounds of a memory buffer in some Intel(R) i915 Graphics drivers for linux before kernel version 6.2.10 may allow an authenticated user to potentially enable escalation of privilege via local access.

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2207644]

Comment 10 Justin M. Forbes 2023-05-30 17:05:31 UTC

While it looks as though the main flaw was fixed with kernel 5.16.19, Fedora is currently on the 6.3 series, and well past the intel recommended 6.2.10
