Published Oct 14, 2023
·
Updated

An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker can trigger a race condition that results in a fillkobjpath out-of-bounds write.

Other sources

Linux Kernel could allow a local authenticated attacker to execute arbitrary code on the system, caused by a race condition that results in a fillkobjpath out-of-bounds write in lib/kobject.c. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition.
