Title
bpf: Fix stackmap overflow check in __bpf_get_stackid()
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix stackmap overflow check in __bpf_get_stackid()
Syzkaller reported a KASAN slab-out-of-bounds write in __bpf_get_stackid()
when copying stack trace data. The issue occurs when the perf trace
contains more stack entries than the stack map bucket can hold,
leading to an out-of-bounds write in the bucket's data array.
Severity
No CVSS data available.
