CVE Details

Release Date:

Description

In the Linux kernel, the following vulnerability has been resolved:\nfirmware: cs_dsp: Fix overflow checking of wmfw header\nFix the checking that firmware file buffer is large enough for the\nwmfw header, to prevent overrunning the buffer.\nThe original code tested that the firmware data buffer contained\nenough bytes for the sums of the size of the structs\nwmfw_header + wmfw_adsp1_sizes + wmfw_footer\nBut wmfw_adsp1_sizes is only used on ADSP1 firmware. For ADSP2 and\nHalo Core the equivalent struct is wmfw_adsp2_sizes, which is\n4 bytes longer. So the length check didn't guarantee that there\nare enough bytes in the firmware buffer for a header with\nwmfw_adsp2_sizes.\nThis patch splits the length check into three separate parts. Each\nof the wmfw_header, wmfw_adsp?_sizes and wmfw_footer are checked\nseparately before they are used.
