Description
This security bulletin contains information about 1 vulnerability.
1) Information disclosure (CVE-ID: CVE-2014-8709)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The ieee80211_fragment function in net/mac80211/tx.c in the Linux kernel before 3.13.5 does not properly maintain a certain tail pointer, which allows remote attackers to obtain sensitive cleartext information by reading packets.
