CVE-2024-53191

| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix warning when unbinding
If there is an error during some initialization related to firmware,
the buffers dp->tx_ring[i].tx_status are released.
However this is released again when the device is unbinded (ath12k_pci),
and we get:
WARNING: CPU: 0 PID: 2098 at mm/slub.c:4689 free_large_kmalloc+0x4d/0x80
Call Trace:
free_large_kmalloc
ath12k_dp_free
ath12k_core_deinit
ath12k_pci_remove
...
The issue is always reproducible from a VM because the MSI addressing
initialization is failing.
In order to fix the issue, just set the buffers to NULL after releasing in
order to avoid the double free. |
