srcu: Delegate work to the boot cpu if using SRCU_SIZE_SMALL
ソース: CVE Program / CVE List V5
脆弱性説明
In the Linux kernel, the following vulnerability has been resolved: srcu: Delegate work to the boot cpu if using SRCU_SIZE_SMALL Commit 994f706872e6 ("srcu: Make Tree SRCU able to operate without snp_node array") assumes that cpu 0 is always online. However, there really are situations when some other CPU is the boot CPU, for example, when booting a kdump kernel with the maxcpus=1 boot parameter. On PowerPC, the kdump kernel can hang as follows: ... [ 1.740036] systemd[1]: Hostname set to <xyz.com> [ 243.686240] INFO: task systemd:1 blocked for more than 122 seconds.
