In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: prevent NULL pointer dereference in mt7925_tx_check_aggr() Move the NULL check for 'sta' before dereferencing it to prevent a possible crash.
AI Analysis
Technical Summary
The Linux kernel mt76 wifi driver for the mt7925 chipset contained a NULL pointer dereference vulnerability in the mt7925_tx_check_aggr() function. This occurred because the code dereferenced the 'sta' pointer without first verifying it was non-NULL, potentially causing a kernel crash. The fix involved adding a NULL check for 'sta' before dereferencing it to prevent this crash condition.
Potential Impact
This vulnerability can cause a denial of service via a kernel crash due to NULL pointer dereference. There is no impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to add the necessary NULL pointer check. Since no explicit patch links or vendor advisories are provided, check the Linux kernel source or distribution updates for the official fix. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
