  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2022-49922
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfc: nfcmrvl: Se corrige una posible fuga de memoria en nfcmrvl_i2c_nci_send(). nfcmrvl_i2c_nci_send() será llamado por nfcmrvl_nci_send(), y skb debería liberarse en nfcmrvl_i2c_nci_send(). Sin embargo, nfcmrvl_nci_send() solo liberará skb cuando i2c_master_send() devuelva >=0, lo que significa que skb sufrirá fugas de memoria si i2c_master_send() falla. Skb se libera independientemente de si i2c_master_send() tiene éxito.
