CVE-2022-49263

Status: AnalyzedMedium (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

brcmfmac: pcie: Release firmwares in the brcmf_pcie_setup error path

This avoids leaking memory if brcmf_chip_get_raminfo fails. Note that the CLM blob is released in the device remove path.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
