一、漏洞信息
漏洞编号:CVE-2024-50270
漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0
CVSS V3.0分值:
BaseScore:5.5 Medium
Vector:CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:mm/damon/core: avoid overflow in damon_feed_loop_next_input()damon_feed_loop_next_input() is inefficient and fragile to overflows. Specifically, score_goal_diff_bp calculation can overflow when score is high. The calculation is actually unnecessary at all because goal isa constant of value 10,000. Calculation of compensation is againfragile to overflow. Final calculation of return value for under-achivingcase is again fragile to overflow when the current score isunder-achieving the target.Add two corner cases handling at the beginning of the function to make thebody easier to read, and rewrite the body of the function to avoidoverflows and the unnecessary bp value calcuation.

CVE-2024-50270

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

mm/damon/core: avoid overflow in damon_feed_loop_next_input()

damon_feed_loop_next_input() is inefficient and fragile to overflows.
Specifically, 'score_goal_diff_bp' calculation can overflow when 'score'
is high. The calculation is actually unnecessary at all because 'goal' is
a constant of value 10,000. Calculation of 'compensation' is again
fragile to overflow. Final calculation of return value for under-achiving
case is again fragile to overflow when the current score is
under-achieving the target.

Add two corner cases handling at the beginning of the function to make the
body easier to read, and rewrite the body of the function to avoid
overflows and the unnecessary bp value calcuation.

The Linux kernel CVE team has assigned CVE-2024-50270 to this issue.
