Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 6.1.1 (Operating System). Affected by this issue is the function module_gzip_decompress of the file kernel/module/decompress.c. The manipulation of the argument module_get_next_page with an unknown input leads to a return value vulnerability. Using CWE to declare the problem leads to CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions. The impact remains unknown. CVE summarizes:

In the Linux kernel before 6.1.2, kernel/module/decompress.c misinterprets the module_get_next_page return value (expects it to be NULL in the error case, whereas it is actually an error pointer).
