Also set dmc_fw_size only\nafter the payload allocation succeeds.\n\n(cherry picked from commit efde6601a1f1daedfe3dcc2816c934ddb44e3eef)","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/05f7a2f712f8b287a98ee61a7c2c6b72dad2fc6d","tags":[]},{"url":"https://git.kernel.org/stable/c/8bb1858db453cd4250e3b633f5d2d09206024ca6","tags":[]},{"url":"https://git.kernel.org/stable/c/dfcfe2874e7c16e8460dc86ac1eeb54ea0e7f8aa","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
