Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： net: microchip: sparx5：在 flower 配置失败时清理 PSFP 资源 函数在添加 VCAP 动作之前，会预先分配 PSFP 流门控（stream gate）、流计量器（flow meter）和流过滤器（stream filter）资源。如果后续步骤失败，这些在函数早期已分配的资源将不会被释放（即未进行回滚）。 修复措施包括：在资源获取后若配置失败，新增错误处理路径以释放流过滤器、流计量器和流门控资源。 此外，修改 函数，使其在遇到“已存在流计量器”

Vulnerability Title
net: microchip: sparx5: clean up PSFP resources on flower setup failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: net: microchip: sparx5: clean up PSFP resources on flower setup failure sparx5_tc_flower_psfp_setup() allocates PSFP stream gate, flow meter and stream filter resources before adding VCAP actions. If a later step fails, the resources allocated earlier in the function are not unwound. Add error paths to release the stream filter, flow meter and stream gate when setup fails after they have been acquired. Also make sparx5_psfp_fm_add() return the acquired flow-meter id before the existing-flow-meter early return. When an existing flow meter is reused, sparx5_psfp_fm_get() increments its pool reference count, but the caller previously kept psfp_fmid as 0. If a later setup step failed, the error path could try to delete flow-meter id 0 instead of the reused flow meter, leaving the incremented reference behind.
