Summary
CVE-2021-46965 is a vulnerability affecting the Linux kernel's mtd (Mass-Storage Driver) subsystem, specifically the physmap-bt1-rom module. The issue involved unintended stack access, which occurred when the variable 'data' was incorrectly cast to a char pointer. Since 'data' is of type u32, any increment to its address would progress in 4-byte chunks, causing the issue. This out-of-bounds access was identified and addressed to prevent potential exploitation.
