漏洞描述
中文描述:

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于qcs615 Coresight设备创建无限循环，可能导致栈溢出。

英文描述:

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: qcom: qcs615: fix a crash issue caused by infinite loop for Coresight An infinite loop has been created by the Coresight devices. When only a source device is enabled, the coresight_find_activated_sysfs_sink function is recursively invoked in an attempt to locate an active sink device, ultimately leading to a stack overflow and system crash. Therefore, disable the replicator1 to break the infinite loop and prevent a potential stack overflow. replicator1_out -> funnel_swao_in6 -> tmc_etf_swao_in -> tmc_etf_swao_out | | replicator1_in replicator_swao_in | | replicator0_out1 replicator_swao_out0 | | replicator0_in funnel_in1_in3 | | tmc_etf_out <- tmc_etf_in <- funnel_merg_out <- funnel_merg_in1 <- funnel_in1_out [call trace] dump_backtrace+0x9c/0x128 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 dump_stack+0x18/0x28 panic+0x340/0x3b0 nmi_panic+0x94/0xa0 panic_bad_stack+0x114/0x138 handle_bad_stack+0x34/0xb8 __bad_stack+0x78/0x80 coresight_find_activated_sysfs_sink+0x28/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] ... coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_enable_sysfs+0x80/0x2a0 [coresight] side effect after the change: Only trace data originating from AOSS can reach the ETF_SWAO and EUD sinks.
