Description Pedro Sampaio 2023-04-03 16:45:45 UTC
SELinux Project SELinux Userspace is vulnerable to a denial of service, caused by a toHeap-use-after-free flaw in the cil_reset_classperms_set
function in libsepol/cil/src/cil_reset_ast.c. By sending a specially-crafted request, a local attacker could exploit this vulnerability to cause a denial of service condition or obtain sensitive information.
