CVE-2023-53397 [MEDIUM] CWE-125 kernel: modpost: fix off by one in is_executable_section()
kernel: modpost: fix off by one in is_executable_section()
In the Linux kernel, the following vulnerability has been resolved:
modpost: fix off by one in is_executable_section()
The > comparison should be >= to prevent an out of bounds array
access.
A flaw was exist's in the Linux kernel’s module-post processing component, in the function is_executable_section(). Due to an off-by-one error (using > instead of >=), the code may perform an out-of-bounds array access.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
