In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix memory leak in ath12k_pci_remove() Kmemleak reported this error: unreferenced object 0xffff1c165cec3060 (size 32): comm "insmod", pid 560, jiffies 4296964570 (age 235.596s) backtrace: [<000000005434db68>] __kmem_cache_alloc_node+0x1f4/0x2c0 [<000000001203b155>] kmalloc_trace+0x40/0x88 [<0000000028adc9c8>] _request_firmware+0xb8/0x608 [<00000000cad1aef7>] firmware_request_nowarn+0x50/0x80 [<000000005011a682>] local_pci_probe+0x48/0xd0 [<00000000077cd295>] pci_device_probe+0xb4/0x200 [<0000000087184c94>] really_probe+0x150/0x2c0 The firmware memory was allocated in ath12k_pci_probe(), but not freed in ath12k_pci_remove() in case ATH12K_FLAG_QMI_FAIL bit is set. So call ath12k_fw_unmap() to free the memory. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.2.0-02280-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1

Base score Version Severity Vector Exploitability Impact Score source
5.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
