HIGHCVSS 7.8/10EPSS 0.12%
Last modified
CVE-2023-28577 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In the function call related to CAM_REQ_MGR_RELEASE_BUF there is no check if the buffer is being used. So when a function called cam_mem_get_cpu_buf to get the kernel va to use, another thread can call CAM_REQ_MGR_RELEASE_BUF to unmap the kernel va which cause UAF of the kernel address.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
