https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114837 Bug ID: 114837 Summary: [11/12/13/14] Fix to security weaknesses in PCS for CMSE Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: ricbal02 at gcc dot gnu.org Target Milestone: --- Security weaknesses exist in PCS for CMSE. To resolve this a patch will be upstreamed and backported which will: 1) When calling a secure function from non-secure code then any arguments smaller than 32-bits that are passed in registers are zero- or sign-extended. 2) After a non-secure function returns into secure code then any return value smaller than 32-bits that is passed in a register is zero- or sign-extended. This patch will fix the following: CVE-2024-0151.
