CWE-787

Description

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.

Affected configurations

• linux linux kernel (>= 3.2.95 < 3.3) • linux linux kernel (>= 3.16.50 < 3.17) • linux linux kernel (>= 4.4 < 4.14.328) • linux linux kernel (>= 4.15 < 4.19.297) • linux linux kernel (>= 4.20 < 5.4.259) • linux linux kernel (>= 5.5 < 5.10.199) • linux linux kernel (>= 5.11 < 5.15.137) • linux linux kernel (>= 5.16 < 6.1.60) • linux linux kernel (>= 6.2 < 6.5.9) • linux linux kernel 6.6
