CVE-2024-36935
Last modified
CVE-2024-36935 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ice: ensure the copied buf is NUL terminated Currently, we allocate a count-sized kernel buffer and copy count bytes from userspace to that buffer. Later, we use sscanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using sscanf. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
Description
In the Linux kernel, the following vulnerability has been resolved: ice: ensure the copied buf is NUL terminated Currently, we allocate a count-sized kernel buffer and copy count bytes from userspace to that buffer. Later, we use sscanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using sscanf. Fix this issue by using memdup_user_nul instead of memdup_user.
