CVE-2026-53113
UnknownSummary
A vulnerability has been identified in the Linux kernel related to memory leaks in beacon template setup in the ath11k module. Functions responsible for memory allocation do not free it on error, leading to memory leaks.
Risk Assessment
Memory leaks can lead to increased resource consumption, which may affect system stability and performance in the long run.
Recommendation
It is recommended to update the Linux kernel to the latest version to mitigate this vulnerability and to monitor the system for potential memory leaks.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix memory leaks in beacon template setup The functions ath11k_mac_setup_bcn_tmpl_ema() and ath11k_mac_setup_bcn_tmpl_mbssid() allocate memory for beacon templates but fail to free it when parameter setup returns an error. Since beacon templates must be released during normal execution, they must also be released in the error handling paths to prevent memory leaks. Fix this by using unified exit paths with proper cleanup in the respective error paths. Compile tested only. Issue found using a prototype static analysis tool and code review.
