Frequently Asked Questions
1
What condition causes the size validation to fail?
The validation can pass incorrectly when a UMP message offset is larger than the buffer length. The fix refactors the check to handle invalid sizes more robustly.
2
How can I determine whether my kernel includes the fix?
Check whether your kernel source or vendor patch set includes either referenced stable commit: fe5c53a952970ba15be8f512babd922e273579de or 556d872e7c2a0b570c5b0974813847ef0d0cd637.
