CVE-2023-54275: wifi: ath11k: Fix memory leak in ath11k_peer_rx_frag_setup
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Fix memory leak in ath11k_peer_rx_frag_setup
crypto_alloc_shash() allocates resources, which should be released by
crypto_free_shash(). When ath11k_peer_find() fails, there has memory
leak. Add missing crypto_free_shash() to fix this.
Security readout for executives and security teams
Plain-English summary
CVE-2023-54275 is a Linux kernel memory leak in the ath11k Wi-Fi driver. If a peer lookup fails after a crypto object is allocated, the driver did not release that object. The source does not provide CVSS, impact scoring, or evidence of active exploitation.
Executive priority
Treat as a targeted kernel maintenance issue unless your environment relies heavily on ath11k wireless devices. Prioritize normal patch cycles, escalating where wireless Linux endpoints are exposed or stability is business-critical.
Technical view
The bug is in ath11k_peer_rx_frag_setup. crypto_alloc_shash() allocates resources that should be released with crypto_free_shash(). When ath11k_peer_find() fails, that release was missing. Kernel stable commits add the missing cleanup path.
Likely exposure
Exposure appears limited to Linux systems running affected kernel versions with the ath11k Wi-Fi driver code in use. The bundle does not map fixes to Linux distributions, packages, hardware models, or runtime configuration requirements.
Exploitation context
The provided sources do not state active exploitation, public exploit availability, or KEV listing. The issue is described as a memory leak fix, but the sources do not quantify denial-of-service feasibility or required attacker position.
Researcher notes
Evidence is limited to the CVE record and upstream stable commit references. There is no CVSS vector, CWE, exploit report, or distro-specific advisory in the bundle, so severity and practical exploitability remain unclear.
Mitigation direction
Check Linux distribution advisories for fixed kernel packages containing the stable commits.
Prioritize kernel updates on systems using the ath11k Wi-Fi driver.
Confirm whether affected fleet assets actually load or require ath11k.
If no vendor fix is available, follow vendor guidance rather than custom workarounds.
Validation and detection
Inventory Linux kernel versions across systems with wireless capability.
Identify systems where the ath11k driver is present or loaded.
Compare installed kernels against vendor advisories and referenced stable commits.
Track remediation through kernel package versions, not only upstream commit hashes.
