CVE-2026-90300 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
bpf: Clear buf on error in __bpf_get_task_stack
Both bpf_get_task_stack and bpf_get_task_stack_sleepable helpers that use __bpf_get_task_stack have buf defined as ARG_PTR_TO_UNINIT_MEM argument and we should initialize the buf on every return path.
Adding missing buf memset for __bpf_get_task_stack fail paths. This provides deterministic buffer contents, which is useful when the buffer is used directly as a map key.
