## Description

In the Linux kernel, the following vulnerability has been resolved:  acct: fix potential integer overflow in encode_comp_t()  The integer overflow is descripted with following codes:   > 317 static comp_t encode_comp_t(u64 value)   > 318 {   > 319         int exp, rnd;     ......   > 341         exp <<= MANTSIZE;   > 342         exp += value;   > 343         return exp;   > 344 }  Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of 'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535.
