CVE-2022-49638 Details
Description
In the Linux kernel, the following vulnerability has been resolved: icmp: Fix data-races around sysctl. While reading icmp sysctl variables, they can be changed concurrently. So, we need to add READ_ONCE() to avoid data-races.
A data-race vulnerability has been identified in the Linux kernel's ICMP implementation, specifically related to sysctl variables. When these variables are read, they can be concurrently modified, leading to potential inconsistencies. To address this issue, the kernel has been updated to include a READ_ONCE() directive, which helps prevent such data-races.
