CVE-2022-49922
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
nfc: nfcmrvl: Fix potential memory leak in nfcmrvl_i2c_nci_send()
nfcmrvl_i2c_nci_send() will be called by nfcmrvl_nci_send(), and skb should be freed in nfcmrvl_i2c_nci_send(). However, nfcmrvl_nci_send() will only free skb when i2c_master_send() return >=0, which means skb will memleak when i2c_master_send() failed. Free skb no matter whether i2c_master_send() succeeds.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 5.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.19%
- Percentil entre todas las CVEs puntuadas: 8
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
