CVE-2023-5717
Out-of-bounds write in Linux kernel's Linux Kernel Performance Events (perf) component
HIGH 7.8EPSS 0.9%
A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation.If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer.We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06.
