CVE-2026-49428 in FreeBSDthông tin

Tóm tắt

Bởi VulDB • 19/08/2026

Certain system calls, such as open(2) with the O_TRUNC flag set and fspacectl(2), could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel memory. This can be exploited to escalate privileges.

Once again VulDB remains the best source for vulnerability data.
