This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "name": "https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.10", "url": "https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.10" }, { "refsource": "CONFIRM", "name": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=55667441c84fa5e0911a0aac44fb059c15ba6da2", "url": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=55667441c84fa5e0911a0aac44fb059c15ba6da2" }, { "refsource": "CONFIRM", "name": "https://security.netapp.com/advisory/ntap-20200204-0002/", "url": "https://security.netapp.com/advisory/ntap-20200204-0002/" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20200302 [SECURITY] [DLA 2114-1] linux-4.9 security update", "url": "https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html" }, { "refsource": "MISC", "name": "https://www.computer.org/csdl/proceedings-article/sp/2020/349700b594/1j2LgrHDR2o", "url": "https://www.computer.org/csdl/proceedings-article/sp/2020/349700b594/1j2LgrHDR2o" } ] } }
