CVE-2026-99210— accel/rocket: clear rdev on device init failure

Quick assessment

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，以下漏洞已得到修复： accel/rocket：在设备初始化失败时清除 rdev rocket_probe() 函数将 rocket_device_init() 的返回值存储到文件作用域的 rdev 指针中，但尚未检查该指针是否为错误指针。若 rocket_device_init() 失败，rdev 会被设置为一个 ERR_PTR（错误指针）。 此外，rdev 指针还被用作标记，以判断共享的 rocket 设备是否已经初始化。因此，后续的核心探测（core probe）可能会看到非 NULL

Vulnerability Title
accel/rocket: clear rdev on device init failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: accel/rocket: clear rdev on device init failure rocket_probe() stores the return value from rocket_device_init() in the file-scoped rdev pointer before checking whether it is an error pointer. If rocket_device_init() fails, rdev is left as an ERR_PTR. The rdev pointer is also used as the marker for whether the shared rocket device has already been initialized. A later core probe can therefore see a non-NULL rdev, skip rocket_device_init(), and dereference the error pointer when reading rdev->num_cores. Save the error code and clear rdev before returning from the rocket_device_init() failure path.
