Detailsinfo

A vulnerability was found in Linux Kernel up to 7.0.9. It has been classified as critical. This affects the function ath11k_mac_setup_bcn_tmpl_ema of the component wifi. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-53113 since 06/09/2026. Technical details are known, but no exploit is available.

Upgrading to version 7.0.10 eliminates this vulnerability. Applying the patch 5d63aa38d5ca85206d9699ffdd616b58780dba07/ff49eba595df500e4ddccc593088c8a4ab5f2c27 is able to eliminate this problem.
