CVE-2022-50749: 
Linux Kernel vulnerability analysis and mitigation

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.
