CVE-2026-53107
UnknownSummary
A vulnerability related to URB handling in interrupt context has been resolved in the Linux kernel. The issue was that URBs could not be killed in interrupt context, potentially leading to data transmission problems.
Risk Assessment
Organizations may face data transmission issues due to improper URB management, which could result in packet loss or communication disruptions.
Recommendation
It is recommended to update the Linux kernel to the latest version to benefit from the fixes related to URB handling in interrupt context.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: don't kill URBs in interrupt context Serialization for the TX path was enforced by calling usb_kill_urb()/usb_kill_anchored_urbs(), to prevent transmission before a previous URB was completed. usb_tx_block() can be called from interrupt context (e.g. in the HCD giveback path), so we can't always use it to kill in-flight URBs. Prevent sleeping during interrupt context by checking the tx_submitted anchor for existing URBs. We now return -EBUSY, to indicate there's a pending request.
